Abstract

A self-testing transceiver comprises a receiver, and a transmitter including a power amplifier (PA) and a plurality of transmitter pre-PA stages. The plurality of transmitter pre-PA stages are configured to generate a communication signal at a receive frequency of the transceiver and the receiver is configured to process another communication signal at a transmit frequency of the transceiver, thereby enabling transceiver self-testing. A method for use by a transceiver for self-testing comprises generating a first communication signal at a transmit frequency of the transceiver by a transmitter of the transceiver, processing the first communication signal by a receiver of the transceiver, generating a second communication signal at a receive frequency of the transceiver by the transmitter, and processing the second communication signal by the receiver. The described generating and processing of the first and second communication signals resulting in self-testing by the transceiver.
