Abstract

A monolithic chip with a single 80-μm HEMT device, 1.25 × 3.0 mm2 in size, has been tested as both a fundamental and a subharmonic mixer. With input filter networks for K- and Q-bands providing two separate radio frequency/local oscillator (RF/LO) channels to the gate, the chip produces an IF signal from dc to 4 GHz at the drain. The mixer operates in three independent modes with the highest conversion gain of 6.9 dB in K-band fundamental mode, the best DSB noise figure of 4.4 dB in Q-band fundamental mode, and better than 20 dB of on-chip LO-to-RF isolation in Q-band subharmonic mode. In all three modes, the active mixer has shown positive conversion gain.
