Low noise broadband MMIC amplifier concept

Zbigniew Nosal

Abstract

Technique of the broadband, low-noise matching of the amplifier input by means of a lossless capacitive feedback is proposed. Bandwidth exceeding one decade with the noise figure on the order 1-1.5 dB and good input matching may be achieved with existing MMIC technologies, which is one of the best noise characteristics reported to date. Prototype 0.5-5 GHz amplifier achieves NF below 1.4 dB and good input matching
