Abstract:
The present disclosure is directed to an apparatus and method for cancelling self-interference caused by full-duplex communication. In a full-duplex communication device, the receiver will generally experience significant self-interference from the full-duplex communication device's own transmitter transmitting a strong outbound signal over the same channel that the receiver is to receive a weak inbound signal. The apparatus and method are configured to adjust a phase and gain of the outbound signal provided at the output of a power amplifier (PA) and inject the phase and gain adjusted outbound signal at the input of a low-noise amplifier (LNA) to cancel the interference from the outbound signal in the inbound signal.

Claim (Index 1):
An apparatus comprising:\n a power amplifier (PA) configured to provide an outbound signal at a differential output of the PA; a low-noise amplifier (LNA) configured to receive an inbound signal at an input of the LNA; and a self-interference cancellation module configured to generate a phase and gain adjusted outbound signal and inject the phase and gain adjusted outbound signal at the input of the LNA, wherein the self-interference cancellation module is configured to adjust the phase of the outbound signal by controllably coupling, using switches, passive elements between the input of the LNA and the differential output of the PA.
