Abstract
A double-antenna radio frequency power detection circuit comprises a radio frequency transceiver, a switching module, a first power detection module, a second power detection module, a first antenna, and a second antenna. The switching module outputs a radio frequency signal received from the radio frequency transceiver, to the first power detection module or the second power detection module according to a switching signal. The first power detection module or the second power detection module respectively detects the transmit power of the radio frequency signal passing through the first antenna or the second antenna, and gives a feedback to the radio frequency transceiver.
