摘要

本文提出了一种支持包括5G频率范围(FR) 1在内的所有蜂窝协议的RF CMOS收发器，该收发器具有18个接收管道和两个发送链。为了有效地将载波聚合(CA)和双频四gnss系统的所有组合的数据传输到调制解调器，实现了全数字接口而不是传统的模拟接口，从而增强了信号完整性并减小了PCB面积。这项工作的数字密集型设计，在14nm CMOS工艺中实现，通过各种数字辅助校准提高了RF/模拟电路的性能。

An RF Transceiver with Full Digital Interface Supporting 5G New Radio FR1 with 3.84Gbps DL/1.92Gbps UL and Dual-Band GNSS in 14nm FinFET CMOS

This paper presents an RF CMOS transceiver supporting all cellular protocols including 5G Frequency Range (FR) 1 with eighteen receiver pipelines and two chains of transmitters. To transfer data for all combinations of carrier aggregation (CA) and a dual-band quad-GNSS system efficiently to a modem, a fully-digital interface is implemented instead of a conventional analog interface, resulting in enhanced signal integrity and smaller PCB area. The digitally-intensive design of this work, implemented in 14nm CMOS process, boosts the performance of RF/analog circuits with various digital-aid calibrations.
