An 18Ghz LNA Ga FET high gain amplifier for WLAN

Abstract

In this article we design a novel ka band low noise amplifier with high stability. in this design Ga FET used to high gain and low noise figure and conditional and unconditional stability. We applied a low noise cost solution for various Ka band receivers such as P-to-P radio, WLAN and UWB sensors. Finally circuit layout with ADS software is presented and very low noise figure about 1.3dB and about 16dB gain was taken.
