An ISM-915 MHz RF transceiver IC

Abstract

A high-performance RF transceiver IC for use in ISM-915 MHz application has been designed. It integrates T/R switch, LNA, mixer, and PA into a TSSOP-20/E package. By using this transceiver IC, it is easy to construct a small size and high performance RF module. In Rx-mode, the overall (including filters and T/R switch) noise figure and conversion gain are 3.5 dB and 25 dB, respectively, at 3 V supply voltage. In Tx-mode, it could transmit 21 dBm output power at 3.3 V voltage supply.
