Description
Technical field
This utility model belongs to communication equipment field, particularly to a kind of radio frequency front-end device.
Background technology
In conventional communication device, power amplifier/LNA is independent from switch, and the circuit relationships between them is as follows:In this circuit, power amplifier/LNA switchs by two discrete module compositions, and both need to link together; Wherein switch module also needs to be connected with antenna oscillator, and power amplifier module also needs to be connected with transceiver channel (TRX). So, whole layout volume is big, and installation is complicated, circuit level is not high.
Utility model content
This utility model is big for conventional radio frequency fore device layout volume, install the defects such as complicated, integrated level is low, devises a radio frequency front-end device that layout volume is little, easy for installation, integrated level is high.
Solution of the present utility model is as follows:
Radio frequency front-end device, mainly includes power amplifier switch module and generally annular mounting structure, and the power amplifier in described power amplifier switch module is integrated on a printed circuit board with on-off circuit, and printed circuit board is fixed in the annular space of mounting structure; Annular outboard in mounting structure is fixedly installed antennal interface, transceiver channel (TRX) port it is fixedly installed in printed circuit board surface, on-off circuit in power amplifier switch module is connected with antennal interface by cable, and the power amplifier in power amplifier switch module is connected with transceiver channel (TRX) port by cable.
On the basis of above solution, this utility model also makees following optimization further:
Power amplifier switch module is also integrated with LNA device.
This radio frequency front-end device also includes cover plate, and cover plate covers and is fixed in mounting structure; Described transceiver channel (TRX) port stretches out lid surface.
Above-mentioned mounting structure is divided into multiple independent structural member, and these independent structural members are on the whole ringwise.
Above-mentioned mounting structure is provided above radiating fin.
This utility model has the advantages that
Modular, easy for installation, volume is little, circuit level is high.
