Reflective Match, Lossy Match, Feedback and Distributed Amplifiers: A Comparison of Multi-Octave Performance Characteristics

The performance of multi-stage single-ended GaAs MESFET amplifiers are compared when employing one and the same transistor type. Supporting experimental results include those of a 3-17.5 GHz reflective match module, a two-stage 2-18 GHz feedback amplifier, a two-stage 2-20 GHz, as well as a four-stage 2-18 GHz distributed amplifier.
