Abstract

A novel Q-band monolithic harmonic mixer has been designed and fabricated using the 0.15 /spl mu/m pseudomorphic InGaAs-GaAs HEMT process for the first time. This high performance mixer is capable of downconverting a Q-band RF signal with the 12th, 14th or 16th harmonic of a S-band LO signal to produce a signal suitable for a phase locked loop. This compact mixer consists of antiparallel HEMT Schottky diodes with a lumped element IF and LO diplexer and a RF band-pass filter. Measured data shows agreement between simulations and measurements. Total chip size is 1.0 mm/spl times/2.5 mm.<>
