Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0035] In the process of R&D, debugging and production line testing of mobile phones, it is necessary to collect data on the performance of mobile phone sending and receiving signals, and make certain adjustments to the performance of mobile phone sending and receiving signals according to the data. In the traditional technology, when the mobile phone uses the antenna to send and receive signals and the radio frequency cable to send and receive signals, the same performance configuration is intelligently arranged, and there is no way to automatically identify the use status of the mobile phone antenna, that is, whether the mobile phone is in the conduction mode or the radiation mode . If the use status of the mobile phone antenna can be known during the test phase, that is, whether the mobile ph...

Abstract

The invention discloses a mobile phone antenna use state detection circuit and belongs to the technical field of mobile phone testing. The detection circuit comprises a switch arranged between an antenna and a power amplifier module. The switch is associated with an insertion action or a pull-out action of a radio frequency cable. An access point is arranged between the switch and the antenna. A positive voltage is connected to the access point. A first load and a voltage detection point further are connected to the access point. A detection system comprising the detection circuit comprises the detection circuit, a performance detection device and an adjusting component. The detection method in which the detection circuit is included comprises the steps of judging whether the switch is switched on or switched off according to level signals output by a voltage detection device, and accordingly judging whether the mobile phone antenna is in use or not. According to the technical scheme, the mobile phone antenna use state detection circuit has the advantages that whether the switch is switched on or switched off is detected through the radio frequency cable, and the voltage detection device detects that the level signals are output, so the use state of the mobile phone antenna can be known, and two modes of performance parameters are obtained when a mobile phone transmits signals.

Description

technical field [0001] The invention relates to the technical field of mobile phone testing, in particular to a mobile phone antenna use state detection circuit. Background technique [0002] In the process of R&D, debugging and production line testing of mobile phones, it is necessary to test and evaluate the performance of sending and receiving signals of mobile phones. In the prior art, the testing of mobile phone sending and receiving signal performance adopts the wired test method of connecting the mobile phone with a radio frequency cable through a connector, rather than through the antenna of the mobile phone itself. The mobile phone test mode under this connection mode is usually called The conduction mode of the mobile phone. In the conduction mode, no matter how many sets of data are obtained from the performance test of sending and receiving signals, it is only related to the wired connection method, and the performance data when the mobile phone uses its own ant...
