W-band subharmonically pumped resistive mixer based on pseudomorphic heterostructure field effect transistor technology

Paper in proceeding, 1993

This paper describes the first subharmonically pumped resistive mixer (SPRM) based on HFETs, operating in the W-band (75-110 GHz). Two HFET devices, specially designed for this application, were integrated together with a coupler, 180° phase shifter, and an IF-filter. Both theoretical and experimental results are presented in this paper. A minimum conversion loss of about 22 dB was experimentally obtained at an LO-power of 10 dBm.
