0.4 watt X-band quasimonolithic amplifier-design, results, comparative analysis of simulating methods

Abstract

The development of the new X-band electronics systems needs amplifiers with output power of 0.3-0.4 W, reliable, not so costly, with small weight and dimensions. This paper concerns design and measured characteristics of experimental quasimonolithic amplifier (QMAMP) with the output power of 0.4 W and the power gain of 12-16 dB in the frequency band 9-12 GHz, and gives comparative analysis of the results of using the small signal S-parameters and the time domain large signal approaches in the design of GaAs power amplifiers.
