INSTALLATIONBOARD PREPARATION Inspect the TR board mounting surface for contamination and any obvious surface obstructions,bumps, or imperfections.
 Inspect the surface for solder and solder flux contaminants, surface should be solder free.
 Use lint free cleaning cloth to wipe the board mounting surface clean of dust and contaminants.
 Apply a few drops of uncontaminated isopropyl ≥70% alcohol to a cleaning cloth to remove
particles that are not easily removed.
 Ensure most alcohol is removed from the PCB surface by wiping the surface with a dry lint freecleaning cloth.


After the board footprint surface has been inspected and cleaned, avoid contact with the board
surface with fingers or other contaminating objects.

 CAUTION: The TR must rest evenly on the board surface to work correctly.
 NOTE: An alternative solution to remove dust is to use a filtered compressed dust can.
 CAUTION: Do not apply large bursts of air pressure to avoid static shock to circuit components.

INSTALLING the STIFFENER BLOCK
For boards thinner than 60 mils (1.5 mm) it is recommended to use a PCB Stiffener Block (Example Part
number SB12X1-2.54-1M) under the PCB to aid in PCB planarity.
 Carefully remove the shipping cover and Stiffener Block from the TR Assembly by loosening theM2 Captive Screws at the top of the Strain Relief Block until they are easy to slide out of thestiffener and PCB (See Figures 1 and 2).
 NOTE: These screws will not completely remove from the TR Assembly in normal use. If thescrews are damaged and need to be replaced, see section Care and Maintenance.

Figure 1: TR Assembly

Figure 2: Protective Bottom Cover and Stiffener Block Removed
from the TR Assembly Once all the M2 mounting screws are removed from the Stiffener Block, the protective Shipping
Cover and the Stiffener Block will fall away from the assembly (See Figure 2).
 Carefully locate the TR board footprint and align the press bosses of the Stiffener Block to theback of the TR footprint on the PCB (See Figures 3 and 4).
 NOTE: The Stiffener Block is symetrical in design so attention to left/right orientation is not
required. The press bosses will hold the Stiffener Block to the PCB backside. At this point, anarbor press MAY be used if necessary to fully seat the bosses on the Stiffener Block.
 With the press bosses aligned and holding the Stiffener Block in place, carefully apply handpressure to press the bosses into the PCB.

AM-031 Rev 6 4-21-16

 NOTE: It is not necessary to fully compress the Stiffener Block to the PCB at this stage. During
further installation of the the TR Assembly, the M2 Captive Screws will fully seat the stiffener
before being fully torqued.

Figure 3: Mounting the Stiffener Block

Figure 4: Mounting the Stiffener Block with Retention

 NOTE: At this stage, optional 0-80 screws may be used to secure the stiffener to the PCB. If
these screws are used, it is vitally important that the screw heads be recessed or below the top
metal mounting plane (See Figure 4).
 NOTE: For boards greater than 60 mils (1.5 mm) M2 pem nuts may be used in place of the
Stiffener Block.
 NOTE: For Boards less than 25 mils thick (flex circuits) consult Ardent.

MOUNTING TR

Diagram 2: Exploded CAD image of TR12X1 assembly mounting on a PCB
 Locate the alignment dowels on the bottom of the TR Assembly and reference them foralignment (See Figure 5).
 CAUTION: Avoid contact with the interface springs to prevent damage.
 Carefully align the two dowel pins with their corresponding holes being sure to align the 1.5mm
dowel pin with the 1.5mm hole and the 1mm dowel slot pin with the 1mm slot hole (See Figure
6).
 NOTE: The 1.5mm dowel will always align near Channel 1.

Figure 5: Aligning the TR Assembly

Figure 6: Holding the TR Assembly in Place Carefully push down on the block and hold it in place (See Figure 6).
 To ensure that the Stiffener Block is aligned with the TR Assembly, push the hex screws in androtate to verify contact.
 If the TR assembly has 3 M2 screws as in a X12 or X24 assemblies, tighten the middle screw
before tightening the side screws (See Figure 7).
 While holding the TR Assembly in place, tighten the M2 hex screws located on top of the Strain
Relief Block until a torqueing resistance is observed (See Figure 8).

Figure 7: Verifying M2 Screw Contact

Figure 8: Tightening the Middle M2 Screw After all the screws have been tightened snuggly into place, go back over the M2 screws withthe driver to be sure they are all torqued evenly to 1.5 in-lbs (0.169Nm).
 NOTE: There will be a noticeably large resistance to turning the screws when they are fullytightened (See Figure 9).

PROCEDURE for CONNECTING the TR COAX CONNECTOR to
INSTRUMENTATIONCAUTION: Care must be considered when assembling connections. Misalignment will significantly
damage the fingers or plug of the coax connector. Time must be taken for proper alignment to ensure
correct measurements. It is best to tighten the connectors as far as possible by hand before using tools.
 Minimize the variable parameters of the cable geometry assembly by supporting and handling itwith care. Do not pull, rotate, or place the cable assembly under tension.
 Verify that calibration ports are gauged, concentric, and set to the right pin depth.
 Carefully align the coax connector to the calibration reference port.
 While holding the cable assembly and adapter port stationary, rotate the coupling nut by hand.
 Hand tighten the connection first.
 Do not force the connection if the coupling nut is not threading smoothly.
 To couple the connection to a repeatable pin depth, grip the base of the female coax connector
by hand or with an open ended wrench.
 Insert the Torque Wrench onto the coupling nut such that it forms an angle less than 90° withthe hand grip or the stationary wrench.
 While holding the coax cables and connectors stationary, apply a moment force with the torquewrench at the coupling nut into the decreasing angle direction. Hold the torque wrench fromthe end (See Figure 11).
 Keep the coax cables and connectors stationary while gently applying the moment force at the
coupling nut just until the torque wrench begins to yield slightly.
 CAUTION: Ensure the coax cables and connectors remain stationary at all times during theconnection to prevent connector wear and measurement error.
 CAUTION: Do not exceed a moment force of 8 in-lb (0.90 Nm) at the coupling nut to avoid
damage and measurement error.
 CAUTION: Inspect the connector coax metal surface for scratches that may contain metal
particles due to open ended wrench wear. Clean to prevent measurement error contamination.

 NOTE: The applied moment force is only at the coupling nut.
 NOTE: The function of the coupling nut is to bring and hold the center conductors to arepeatable depth.

DISCONNECTING TR FROM INSTRUMENTATION
 Carefully hold the device under test and instrument cables stationary by hand or with thecorresponding permissible open ended wrenches: 5/32”, 5/16”, or 7mm.
 Repeat the connection procedure with an opposite moment force for disconnection.
 Place the torque wrench on the coupling nut and apply a steady moment force to loosen theconnection with the torque wrench.
 When the moment force resistance feels released, continue to uncouple the connection by
hand.

EXPECTED RESULTS
EVALUATION KIT
The scattering parameter performance of the TR Assembly can be observed by an Evaluation Kit offered.
The Evaluation Kit contains a TR Assembly, PCB mounting board with microstrip traces, and two
movable end launch connectors.
EVALUATION KIT BOARD
There is an 8 channel evaluation kit available with 2.92 mm (K- Connector) 6” cables.
The board is 62 mils thick with Rogers 3003 (10 mils thick) substrate ENIG laminated onto FR4.
Each metal layer is 1.7 mils thick with ENIG plating.
The board has two line standards to de-embed board loss.
The L2 / M line standard is 0.50” long and can also be used as an open to move the reference
plane just before the narrow microstrip transition.
The L1 / M line standard is 0.75” long.
A load adapter may be connected to one end of the line standards.
With the L2 / M line open standard, the reference plane extension determines a characterized
attenuation with the end launch and microstrip. The loss characterization is determined by the
PNA when measuring the open standard.
PLEASE NOTE: The loss of the microstrip trace under the interface still remains and therefore
further characterization would be implemented to completely remove the microstrip trace up to
the signal landing pads.
PLEASE NOTE: To ensure a correct de-embedded return loss measurement, ideally part of the
microstrip trace would be included just before entering under the interface.
END LAUNCH CONNECTOR
Each Evaluation Kit contains two Signal Microwave Edge Launch Connectors: 2.92 mm Female.

DETERMINING PHASE LENGTH
 To determine the phase length of each cable: Remove the interface from the TR Assembly.
 Note: Phase length measurements will not be accurate with the interface on the TR assembly
because the contacts are not compressed.
 In the time domain, select a step response in real format mode.
 Connect a TR coax channel to the calibrated port.
 Allow time for a steady state response.
 Determine and mark the middle of the step response rise and record the time value.
 This chosen middle value will be used as a reference.
 Average for what time the chosen middle rise value would fall on.
 Disconnect the channel and connect a new channel.
 Allow time for a steady state step response.
 Determine and mark the middle of the step response rise and record the time value.
 Average for what time the chosen middle rise value would fall on.
 Repeat this process and when completed, the different time values for when the chosen middle
value of the step response rise occurred can be compared.

TR BOARD OPTIMIZATIONOPTIMIZATION PROCEDURE
 The optimization checklist provides the input parameters for simulating the unique information
stack up of every board. This must be filled out prior to beginning any optimization work.
 For the TR assembly there is an optional optimization report that determines footprint
specification parameters for improved impedance matching.
 The default optimization return loss performance for the TR assembly at the connector is -20 dB
for up to 20 GHz and -12 dB from 20 GHz to 40 GHz.
 The current footprint for the connector has tolerance limitations for modifications.

HFSS SIMULATIONThe simulation determines the optimal board footprint parameters for TR. The simulation models
the performance of a signal as it transitions under the connector, thru the interface, and up to a few
inches of coax cable.
 A complete model of the connector is simulated with the corresponding board stack up,
optimization goals, references, and desired performance specifications requested.
 Simulations are available for a microstrip and a stripline.

The parameters kept constant for simulation optimizations are the following: Gap width under the connector.
 Anti-pad ground diameter and microstrip top metal return channel width (guard
channel).
 Via diameter Return via bolt circle diameter Return via location on the bolt circle

NOTE: The current footprint for the connector has tolerance limitations for modifications.
The Time Domain Reflection graph provides a high resolution image of impedance values with a risetime of 25 ps for a frequency span bandwidth of 40 GHz.
NOTE: The graphs provide a forward and reverse pathway thru the connector (legend indicated by coax
and microstrip), (See Figures 19-21).

NARROW TRACE TRANSITION UNDER TR ASSEMBLY
Since there is a grounded metal air gap channel under the connector, a capacitive
reaction will occur and a narrower inductive trace is required under the connector.
A model of the interface is included in the simulation and the channel height is 4.5 mils.
The HFSS simulation models the narrow trace transition with approximately 0.5 inches of the incident
board trace.

FINAL BOARD REVIEW
After the board optimization parameters have been verified and implemented, a new board file is sent
to Ardent Engineering to verify that TR will be compatible with your board.
Procedure Includes:
Verification of Footprint Specification Tolerances with Cadence Board File Viewer
NOTE: The final board review does not contain HFSS model, only simulation results. A model may beattainable. Please consult factory here.
After the board file has been reviewed, specifications or configurations measured out of tolerance are
noted and corrections are recommended.
Approval of a board footprint is awarded when specifications are determined within tolerance.
The final board review will also communicate reminders of important parameters to consider.
IMPORTANT NOTE
Verify Board Integration:
 Filled Contact Vias No Soldermask Area under Connector
 No Narrow Trace Width Tapers
