Abstract :
A fully integrated MMIC (microwave monolithic integrated circuit) receiver was designed and fabricated using the ion-implanted GaAs MESFET 0.5 mu m process. This MMIC receiver incorporates a two-stage RF amplifier, a two-stage LO (local oscillator) amplifier, an IF (intermediate frequency) amplifier, and a singly balanced diode mixer. Better than 10 dB conversion gain is achieved from 9 to 20 GHz. The LO to IF isolation is better than 30 dB. This chip operates from a single +5 VDC and draws 175 mA. Total chip size is 3.5 mm*3.0 mm.<>
