2-18 GHz GaAs Monolithic Ultra-Broadband Amplifier

摘要

The design principle and research process of 2 to 18 GHz GaAs microwave low noise ultrabroadband monolithic amplifier is described in this paper. Its final results are presented in 2-18 GHz freuqency range, the noise figure is 4.2-6.2 dB, the gain is 13.5-18.3 dB, input VSWR is less than 2.0, output VSWR is less than 2.5 for a packaged two stage amplifier.
