Abstract
(EN)
Provided are a radio-frequency apparatus and a terminal device. The radio-frequency apparatus comprises: a radio-frequency transceiver; a first switch; an antenna, with the antenna being connected to the first switch; a channel connection device, with the channel connection device being connected to the first switch; a transmit and receive channel located between the radio-frequency transceiver and the first switch; and a diversity receive channel and a power detection channel, located between the radio-frequency transceiver and the channel connection device, wherein a first radio-frequency transmission signal sent by the radio-frequency transceiver is transmitted, via the transmit and receive channel, to the antenna by means of the first switch; and second radio-frequency transmission signals in the first radio-frequency transmission signal are transmitted back to the radio-frequency transceiver via the channel connection device and the power detection channel in sequence.
