DOI: 10.1109/tcsi.2019.2905877
Abstract: 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… read more here.
