A Fully-Integrated, 0.5 Watt, 2 to 6 GHz MMIC Amplifier

Abstract

A fully integrated 2-6 GHz, two-stage, 0.5 watt MMIC amplifier has been designed, fabricated and tested. This single-chip amplifier features a gain of 14.5 +/- 0.9 dB, an input VSWR better than 2:1 and an output power greater than 0.5 watt. Chip size is only 1.0 by 2.0 mm. Both small and large signal FET models used in the design are software generated, with measured data used for comparison. We believe this to be the first published paper reporting such a single-ended MMIC power amplifier with high gain and output power over such bandwidths within a chip area of 2 square mm.
