Low power 3 similar to 8-GHz UWB tunable LNA design using SiP technology

Abstract

In this paper we present a tunable ultra-wideband LNA using system-in-package solution to enhance gain and noise performance. Several high-Q MEMS inductors are employed at the input matching network and the tunable resonator load. SiP integration is realized by Au-Au thermal compression bond of low electrical parasitic effects. It is found those inductors improve noise figure by 2dB and help achieve gain flatness in a broad frequency range of 3- to 8-GRz.
