A 5 GHz wide band input and output matched low noise amplifier

Published: 11 March 2007 Publication History

Abstract

In this paper the design of a 5 GHz wide band matched low noise amplifier (LNA) is presented. The LNA uses a conventional cascode architecture and was implemented in IBM SiGe5AM technology. Powered by a 1.8-V supply the LNA features 11.5 dB of gain and a 1.2 dBm noise figure. The LNA has a bandwidth of 3 GHz which makes is suitable for wide band applications. The LNA draws only 8mA current and is stable over a wide frequency range. Input and output return losses of -10dB and -13dB have been achieved.
