Abstract

A S-Band MMIC LNA for satellite communication system is designed with cascade feedback structure and fabricated using 0.15-um GaAs pHEMT process. The small signal gain of the LNA is 22dB at room temperature. The gain flatness is less than 2dB among the whole bandwidth. The typical noise figure is less than 1.4dB at room temperature. The chip area is 1.5mm². The return loss shows good performance while maintains noise impedance matching by applying RC feedback to traditional structure.
