Abstract

The invention provides a radio frequency PA Mid device, a radio frequency system and a communication device. The radio frequency PA Mid device is configured with a coupling output port, a coupling input port and an antenna port, and the radio frequency PA Mid device comprises a transmit-receive circuit used for supporting transmit-receive control of radio frequency signals; a coupling unit which comprises an input port, an output port and a first coupling port, and is used for coupling the radio frequency signal and outputting a forward coupling signal; a second coupling port which is used for coupling reflection signals of the radio frequency signals and outputting reverse coupling signals; and a coupling switch which is used for selectively outputting the forward coupling signal, the backward coupling signal or the external coupling signal received by the coupling input port through the coupling output port, so that a plug-in switch can be prevented from being additionally arranged between the radio frequency PA Mid device and the radio frequency transceiver, the space is saved, and the cost is reduced.

Description

technical field [0001] The present application relates to the field of radio frequency technology, in particular to a radio frequency PA Mid device, radio frequency system and communication equipment. Background technique [0002] With the development and progress of technology, 5G mobile communication technology has gradually begun to be applied to electronic devices. The communication frequency of 5G mobile communication technology is higher than that of 4G mobile communication technology. Generally, multiple switches can be set in the feedback detection channel in the radio frequency system to support the coupling switching control before multiple radio frequency signals, so as to realize the power detection of multiple different coupling signals, which is costly and occupies a large area. Contents of the invention [0003] Embodiments of the present application provide a radio frequency PA Mid device, a radio frequency system and communication equipment, which can sav...
