Abstract

This paper discusses the design and performance of a multi-stage wideband GaAs MESFET amplifier. The amplifier had a small signal gain of 12 to 20 dB in the frequency range of 2 to 18 GHz. The l-dB gain-compression point of the amplifier was 13 dBm and the saturated power output exceeded 16 dBm. The wideband matching techniques used and the trade-offs involved are discussed. Also discussed are the device parameters and their relationships to the performance of the amplifier.
