Abstract

An ideal Software Defined Radio (SDR) requires a reconfigurable, intergrated, widely-frequency-tunable transceiver able to support different RX/TX duplex schemes. Here we present an integrated transceiver capable of supporting both TDD and FDD operation with >25dB integrated RX-TX isolation from 0.3-1.6GHz without any off-chip switches or filters. The transceiver uses an artificial transmission line (TL) and distributed PA to separate TX and RX. TX noise in the RX band is further suppressed by >13dB an RX-tracking PA degeneration circuit.

一个完全集成的软件定义FDD收发器，可在0.3至1.6 GHz范围内调谐

理想的软件定义无线电(SDR)需要一个可重构的、集成的、宽频率可调的收发器，能够支持不同的RX/TX双工方案。在这里，我们提出了一种集成收发器，能够支持TDD和FDD操作，在0.3-1.6GHz范围内具有>25dB集成RX-TX隔离，无需任何片外开关或滤波器。收发器使用人工传输线(TL)和分布式PA来分离TX和RX。RX波段的TX噪声被>13dB的RX跟踪PA退化电路进一步抑制。
