在这封信中，六端口收发器频分双工（FDD）系统的建议和实验证明。该收发器由一个六端口相关器和四个肖特基二极管组成，可以在不同的频率下同时实现调制和解调。为了验证所提出的架构，六端口收发器系统原型的开发，和调制和解调性能进行了评估，分别使用正交幅度调制信号在2.9和2.68 GHz。此外，提出了一种用于六端口收发器的外差解调，以减轻基带调制信号的干扰。基于该收发器的FDD系统的误差矢量幅度低于2%。
In this letter, a six-port transceiver for frequency-division duplex (FDD) systems is proposed and experimentally demonstrated. The proposed transceiver that consists of a single six-port correlator and four Schottky diodes can realize both modulation and demodulation simultaneously at different frequencies. To verify the proposed architecture, the six-port transceiver system prototypes are developed, and modulation and demodulation performances are evaluated by using quadrature amplitude modulation signals at 2.9 and 2.68 GHz, respectively. Moreover, the heterodyne demodulation for a six-port transceiver is proposed to mitigate the interferences from baseband modulation signals. The error vector magnitudes of FDD systems based on the proposed transceiver are found below 2%.
