Robust AlGaN/GaN MMIC Receiver Components

Abstract

Apart from deliveringvery high output powers, GaN can also be used to realize robust receiver components, such as Low Noise Amplifiersand Switches. This paper presents the designand measurement results of two GaN X-band switch and LNA MMICs, designed for integration in aradar front end. The switch design shows a1dB compression point of 43 dBm and can withstand input powers of over46dBm. The LNA design shows an input power handling capability of 41 dBm. These results demonstrate the capability of realizing robust receivers with GaN, farbeyond what is currently possible using GaAs.
