摘要： A method includes receiving (506) a radio frequency (RF) input signal (108) using at least one non-reciprocal circulator (102, 402). The method also includes generating (510) an RF output signal (110) using at least one of multiple reflective filter elements (104a-104n, 404a-404b). Each reflective filter element is configured to receive an RF signal from the at least one non-reciprocal circulator and to provide a filtered RF signal to the at least one non-reciprocal circulator. The reflective filter elements include amplitude change reflectors configured to modify amplitudes of the RF signal at different frequencies. The RF output signal represents the RF input signal as modified (508) by the at least one of the reflective filter elements.

摘要： A circuit comprising a differential transmission line and eight switches provides non- reciprocal signal flow. In some embodiments, the circuit can be driven by four local oscillator signals using a boosting circuit. The circuit can be used to form a gyrator. The circuit can be used to form a circulator. The circuit can be used to form three-port circulator than can provide direction signal flow between a transmitter and an antenna and from the antenna to a receiver. The three-port circulator can be used to implement a full duplex transceiver that uses a single antenna for transmitting and receiving.
