摘要

In this article we demonstrate that the HEMT technology can be applied to MESFET based microwave monolithic integrated circuits to yield improved per­formance margins. Typical performance for the low-noise (LNA) and wideband (TWA) amplifiers studied are: for the HEMT-LNA » 2.2 dB noise figure and » 26 dB gain at 12 GHz in comparison with » 2.8 dB noise figure and »20 dB gain for the MESFET-LNA; for the HEMT-TWA » 8 dB. gain in the frequency range 0.2 to 18 GHz as composed to » 6 dB gain for the MESFET-TWA.
