W-Band Subharmonically Pumped Mixer

SFS-75311416-10VFSF-S1Model SFS-75311416-10VFSF-S1 is a W-Band, subharmonically pumped mixer. The mixer employs high performance GaAs Schottky beamlead diodes, balanced configuration to produce superior RF performance. The subharmonically pumped mixer is capable for full RF waveguide band operation for RF frequencies from 75 to 110 GHz with half of the LO frequency: 37.5 to 55.0 GHz. The conversion loss measured was 12 to 16 dB at +13 dBm LO pumping level typically.
