RADAR Millimeter Wave Source top

creates mmW signal

ATF-36xxx 150 GHz fmax, 100 GHz ft PHEMTs
ATF-13xxx 100 GHz fmax 40 GHz ft GaAs FETs will work well for the 10.5 GHz systems

RADAR Millimeter Wave Mixer top

downconverts signal from mmW to RF

HSCH-9201 Schottky diode series pair for balanced mixers
HSCH-9251 Schottky diode anti-parallel pair for subharmonic LO mixers

HSMS-820x will work well as the mixer for the 10.5 GHz systems


Amplifies intermediate frequency signal for further processing
