摘要

本文描述了第一个用于移动卫星业务的单芯片收发器，它不需要外部混频器，LNA或中频滤波器。该集成电路支持低轨道卫星星座，包括使用L波段小卫星的星座，最高可达每秒240k个符号(ksps)。RFIC允许在新应用中实现全球数据连接，并使远程设备和传感器能够连接到物联网。该芯片集成了从数字到射频的TX和双RX路径，并包括用于PA线性化的DPD算法和反馈路径。

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

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.
