A single-chip K-band receiver

A high-complexity, single-chip K-band receiver, implemented in a GaAs MESFET IC, is demonstrated. This chip contains an RF amplifier, a dual-gate mixer, a rat-race hybrid, a balanced FET doubler, an L-band IF amplifier, and an on-chip filter. The chip size is 110*160 square mils. The chip shows an RF to IF conversion gain of 30 dB, and the spurious response at least 50 dB lower than the signal. The DC power consumption for this single-chip receiver is 580 mW.<
