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

Abstract

Describes the first subharmonically pumped resistive mixer (SPRM) based on heterostructure field effect transistors (HFETs), operating in the W-band (75-110 GHz). Two HFET devices, specially designed for this application, were integrated together with a coupler, a 180 degrees C phase shifter, and an intermediate-frequency (IF) filter. Theoretical and experimental results are presented. A minimum conversion loss of about 22 dB was experimentally obtained at a local-oscillator (LO) power of 1 dBm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
