MAGNETIC-FREE NON-RECIPROCAL CIRCUITS BASED ON SUB-HARMONIC SPATIO-TEMPORAL CONDUCTANCE MODULATION

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.
