在本文中，我们提出了频分双工（FDD）集成收发器的挑战的概述，并提出了新的架构概念，可以满足苛刻的FDD性能要求，并完全集成在芯片上。使用台积电的65 nm体CMOS技术的系统级仿真证实，所提出的架构可以在FDD模式下工作，TX功率高于20 dBm，在天线失配和高TX本底噪声的情况下，TX和RX插入损耗在大于1 GHz的频率范围内的衰减低于1 dB。
In this paper, we present an overview of the challenges in frequency division duplex (FDD) integrated transceivers and propose new architectural concepts that can meet demanding FDD performance requirements and be fully integrated on-chip. System-level simulations using TSMC's 65 nm bulk CMOS technology confirm that the proposed architectures can operate in FDD mode for TX powers higher than 20 dBm with lower than 1 dB degradation in TX and RX insertion losses over a frequency range wider than 1 GHz under antenna mismatches and high TX noise floor.
