摘要：
An RF front end device called the Transmit Isolating Receiver (TIRx) takes the place of both a circulator and low noise amplifier in a conventional RF front end, enabling full-duplex wireless communication by transmitting and receiving simultaneously on the same frequency through a single antenna. The TIRx RF front end enables single channel full duplex communications by providing a high degree of T/R isolation, exceeding 40 dB over four decades of bandwidth. When combined with appropriate digital interference cancellation, systems delivered with the TIRx RF front end have achieved >80 dB of T/R isolation over multiple frequency bands even when connected to an antenna with poor return loss.
