Abstract

The embodiment of the invention provides a radio frequency front end circuit of a mobile terminal and a whole machine coupling testing method. The radio frequency front end circuit comprises a master antenna, a diversity antenna, a diversity antenna switch and a first power detection circuit, wherein the diversity antenna uses coupling effects between the master antenna and the diversity antenna and receives testing signals transmitted by the master antenna; the input end of the diversity antenna switch is connected with the diversity antenna for receiving the testing signals from the diversity antenna; the output end of the diversity antenna switch is used for outputting the testing signals to the first power detection circuit; and the first power detection circuit is used for carrying out power detection on the testing signals to realize whole machine coupling test on the mobile terminal. Thus, dependence on an integrated test instrument can be eliminated, and the hardware cost in the case of whole machine coupling test is reduced.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly to a radio frequency front-end circuit of a mobile terminal in the field of communication and a coupling test method for the whole machine. Background technique [0002] After the production and assembly of mobile terminals such as mobile phones, network cards, and data cards, the coupling test of the whole machine must be carried out to verify whether the wireless communication function of the mobile terminal is normal. Specifically, it is to verify whether the radio frequency function of the mobile terminal is normal and whether there is a good match between the antenna and the main board. During the whole machine coupling test, the mobile terminal under test establishes a connection with the comprehensive tester through signaling or non-signaling, and judges the wireless communication of the mobile terminal under test by judging the transmitting power of the main ante...
