Z Deng, HJ Qian, X Luo - IEEE Transactions on Circuits and Systems I: Regular …, 2019

In this paper, a tunable quasi-circulator (QC) is proposed, which consists of a compact fully-reconfigurable 180° hybrid and two amplifier stages in the transmitter (TX)-and receiver (RX)-paths, respectively. Such hybrid is implemented by six …
