STC-75311405-10-C1

Rev 1.0

Description:
Model STC-75311405-10-C1 is a W-Band downconverter that converts millimeterwave signals from thefrequency range of 75 to 110 GHz to the baseband at 6to 41 GHz. The down-converter has a built-in phaselocked oscillator (PLO), which is externally referenced at
10 MHz. The down converter also integrates a PIN diodebased SPDT switch at the RF input for bypassing in orderto monitor the receiving signal level. The switch iscontrolled by TTL signal and the bypassing “on” is at TTL“high.” The bypassing loss is 4 dB typical and 6 dB maximum. The RF ports for the downconverter is WR10 waveguides with UG-387/U-M flange. The IF output is a K(F) connector and PLO reference signal
input connector is an SMA (F) connector. A wall mount AC adapter is included for AC powering.
