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

Paper i 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.
