发明名称 Wireless transceiver with circulator-based quadrature duplexer and methods for use therewith
摘要 A wireless transceiver includes a transmit path configured to generate a radio frequency (RF) transmit signal for transmission via an antenna. A receive path is configured to receive an RF receive signal via the antenna. A circulator-based quadrature duplexer includes an in-phase circulator and a quadrature-phase circulator configured to couple the transmit signal from the transmit path to the antenna while generating a residual transmit signal on the receive path, and to couple the receive signal from the antenna to the receive path. The circulator-based quadrature duplexer promotes cancellation of the residual transmit signal on the receive path.

主权项 1. A wireless transceiver comprising: a transmit path configured to generate a radio frequency (RF) transmit signal for transmission via an antenna; a receive path configured to receive an RF receive signal via the antenna; and a circulator-based quadrature duplexer including an in-phase circulator and a quadrature-phase circulator configured to couple the RF transmit signal from the transmit path to the antenna while generating a residual transmit signal on the receive path, and to couple the RF receive signal from the antenna to the receive path, wherein the circulator-based quadrature duplexer provides cancellation of the residual transmit signal on the receive path.
