Thermal resistance of heatsink approx 1.5 K/W
For permanent mounting, remove the heatsink from the amplifier. In thatcase, ensure that adequate cooling of the amplifier is guaranteed.
To remove the heatsink from the amplifier, unscrew the four screws on theheatsink.
The view of the amplifier without heatsink is shown on the following page.

The SHF 115 BP is a three stage
amplifier design using specialmonolithic microwave integrated
circuits (MMICs) inside hermetic
carriers to achieve ultra wide
bandwidthandlownoise
performance. The custom made
MMIC carrier is optimized for good
input return loss between its
interior and the 50 Ω outside hybridtechnology.
Thecomputer
optimized broadband circuit isindividually tuned for minimum
passbandripple.
Avoltage
regulator IC makes the amplifier
insensitive to overvoltage and line
ripple.

User Instructions
ATTENTION!
ELECTROSTATIC SENSITIVE GaAs FET AMPLIFIER
1. To prevent damage through static charge build up, cables should be always
discharged before connecting them to the amplifier!
2. Attach a 50 Ohm output load BEFORE supplying DC power to the amplifier!
3. The supply voltage can be taken from any regular 11 to 15 V, 0.8 A DC
power supply and can be connected to the supply feed-through filter via an
ON / OFF switch.
4. The minimum supply voltage is 11 V. A higher one increases the power
dissipation of the internal voltage stabilizer.
5. Using a 3 dB or 6 dB input attenuator will result in a 6 dB or 12 dB increaseof the input return loss. For minimal degradation of amplifier rise time,these attenuators should have a bandwidth specification of greater 50 GHz(V/ 1.85mm or 2.4mm attenuators)!
6. An input signal of about 0.56 Vpp, equivalent to –1 dBm, will produce thefull swing output of 10 Vpp .
7. Higher input voltages will drive the amplifier’s output stage into saturation,
leading to waveform peak clipping.
8. Saturated output voltages can only be used within the operating frequency
range without damage while the amplifier is connected to a 50 Ohm
precision load with a VSWR of less than 1.2 or better than 20 dB return loss
up to the highest operating frequency (i.e, that limited by the K- or Vattenuator).
9. While using a reflective load, the output voltage has to be reduced to a safe
operating level below 10 Vpp according to the magnitudes of the reflections.
ATTENTION: At frequencies up to 20 GHz, a capacitive load can betransformed to an inductive one through transmission lines! With an output
stage driven into saturation this will lead to the immediate destruction ofthe amplifier (within a few ps)!
10. The input voltage should never be greater than 1 Vpp, equivalent to 4 dBm
input power.
11. Hint: Pulse shape tuning of the amplifier has been performed after warm up
at about 40 °C case temperature. Considerably more over- and undershootwill be present at low temperature!
