Single-chip RF Front-end with T/R Switch on Standard Silicon Technology for 5-GHz WLANs

Abstract

A fully integrated RF front-end on standard silicon technology for 5-GHz indoor WLAN applications is presented. It includes an innovative T/R antenna switch which does not require any additional technological steps and provides better performance (the measured insertion losses are 0.2 and 0.9 dB, in R and T modes respectively) with respect to those obtained by using PIN diodes as switching elements
