摘要

软件定义无线电(SDR)能够支持广泛的传统和未来系统，必须与频分双工(FDD)操作兼容。我们最近展示了一种具有FDD功能的集成SDR (SD-FDD)，该SDR在宽带上实现了>25dB的TX和RX隔离，同时支持高TX功率。该收发器采用人工传输线和频率选择性TX退化来满足FDD-SDR的各种要求。本文对该结构进行了分析，并给出了选择和校准发射机复杂输入权重的方法。描述了关键的退化参数及其对噪声的影响。

Broadly tunable frequency division duplex transceiver: Theory and operation

Software defined radios (SDR) capable of supporting a wide range of legacy and future systems must be compatible with frequency division duplex (FDD) operation. We have recently demonstrated an FDD capable, integrated SDR (SD-FDD) that achieves >25dB isolation of TX and RX across a wide band while supporting high TX power. This transceiver employs an artificial transmission line and frequency selective TX degeneration to meet the various requirements of FDD-SDR. In this paper, this architecture is analyzed and methods to choose and calibrate the complex input weights of the transmitter are derived. The key degeneration parameters are characterized and how they affect noise is described.
