Description
The SHF 603 A is a 2:1 Multiplexer operating at data rates up to 120 Gbps for use in broadband test
setups and telecom transmission systems. Two single ended serial data streams of up to 60 Gbps are
accepted by the multiplexer and converted into one differential data signal of up to 120 Gbps. A single
ended clock signal with a frequency half of the output data rate drives the SHF 603 A. All RF in- andoutput ports are AC-coupled and internally terminated with 50 Ohm to GND. Unused in- or output ports
should be terminated with 50 Ohm.

FeaturesBroadband operation up to 120 Gbps

Bias Board
At delivery, the bias board is mounted on a common base plate, together with the SHF 603 A MUX. Whenusing the bias board only one supply voltage of +12V needs to be applied. All operating voltages will be
provided by the bias board.
It is recommended to use the Bias Board only with the delivered power supply. Using other power
supplies can damage the Bias Board.
With the factory settings all bias voltages are set to optimum / maximum output voltage. However, if
required the customer can adjust the output level “VEE3/4” and the clock bias voltage “CLB” with theappropriate trim potentiometers on the bias board.
For system applications it is possible to remove the bias board. In that case the operating voltages haveto be supplied by the customer’s circuitry.
Output Level Control “VEE4”
Output Level Control “VEE3”
Clock Bias Adjust “CLB”+12V

Output Level Adjustment
Output signal amplitude can be reduced by adjusting VEE3 and VEE4 as shown below.
