Abstract
A wireless transceiver apparatus includes a power detector, an analog signal receiving circuit at wireless signal reception side, and a processing circuit. The power detector is configured at wireless signal transmission side and used for detecting power of a power amplifier on a transmitting path of wireless signal transmission side. The analog signal receiving circuit is couple to the power detector and used for receiving a wireless signal form an antenna. Under signal reception mode, the analog signal receiving circuit transmits the received wireless signal to the processing circuit. Under interference detection mode, the analog signal receiving circuit transfers the received wireless signal (as interference) to the power detector, and the power detector is used for detecting the power of wireless signal to measure an interference power value and transmit the value to the processing circuit.
