A Highly Integrated Transceiver for Mobile Satellite Services User Terminals Incorporating Dual Receivers for Satellite Handover and Digital Pre-Distortion for PA Linearization on 0.18μm CMOS

Abstract

This paper describes the first single chip transceiver for Mobile Satellite Services that does not require external mixers, LNA or IF filter. The IC supports LEO satellite constellations including those using small satellites in L band up to 240k symbols per second (ksps). The RFIC allows data connectivity globally in new applications and enables remote devices and sensors to be connected to the Internet of Things. The chip integrates TX and dual RX paths from digital to RF and includes a DPD algorithm for PA linearization with a feedback path.
