Abstract :
An LO-rejecting millimeterwave balanced resistive HFET-upconverter based on a dual FET configuration is investigated. Theoretical and experimental results for a 50-60 GHz upconverter as a function of local oscillator power and gate bias voltage, Vgb, is presented. A conversion loss and LO-rejection of 10 dB and 35 dB is experimentally obtained at an LO-power of 5 dBm.
