Title
(EN) Radio frequency device and terminal equipment
(ZH) 一种射频装置及终端设备
Abstract
(EN)
The invention provides a radio frequency device and terminal equipment, and the radio frequency device comprises a radio frequency transceiver; a first switch; an antenna which is connected with the first switch; a access connecting device which is connected with the first switch; a transmitting and receiving path which is positioned between the radio frequency transceiver and the first switch; adiversity receiving channel and a power detection channel which are positioned between the radio frequency transceiver and the channel connecting device, wherein a first radio frequency transmitting signal sent by the radio frequency transceiver is transmitted to the antenna through the transmitting and receiving channel and the first switch, and a second radio frequency transmitting signal in thefirst radio frequency transmitting signal is transmitted back to the radio frequency transceiver through the channel connecting device and the power detection path in sequence. According to the invention, the insertion loss of a directional coupler in a transmitting and receiving path in the prior art is cancelled, so that the power consumption of a device in the transmitting and receiving path can be reduced under the condition of the same transmitting power, the receiving sensitivity of main set receiving is not influenced, and the radio frequency receiving performance can be improved.
