Embodiment Construction

[0021] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0022] At present, the radio frequency test of the terminal mainly uses the conduction test, and uses the radio frequency feeder to connect the device under test and the test instrument. However, with the use of large-scale antenna arrays on the millimeter-wave terminal side, the wireless transceiver of the terminal is integrated into the antenna to form an antenna module. The millimeter-wave terminal no longer has a radio frequency...

Abstract

The invention discloses a radio frequency test method, which be executed in a mobile terminal. The mobile terminal comprises a transceiver, a radio frequency front end and an antenna; and the radio frequency front end comprises a transmitting channel and a receiving channel. The method comprises the following steps: detecting the return loss received by the transceiver and a power difference returned by a feedback network; and in the case where the return loss exceeds a predetermined threshold and / or the power difference is not equal to the predetermined power, determining that the radio frequency transmitting channel is abnormal. According to the scheme of the invention, a millimeter wave radio frequency channel can be detected and debugged, so that impedance between the antenna and the transceiver can be matched by adjusting parameters of the radio frequency front end.

Description

technical field [0001] The invention relates to the technical field of radio frequency testing, in particular to a radio frequency testing method, a mobile terminal and a storage medium. Background technique [0002] With the rapid development of mobile communications, millimeter wave technology, one of the key technologies of 5G, has become the focus of research. Millimeter waves refer to electromagnetic waves with a frequency of 30GHZ-300GHZ. Due to their high frequency and large bandwidth, the impact of millimeter waves on terminals mainly lies in antennas and RF front-end devices. The traditional radio frequency test method judges the path of the radio frequency through the conduction test, and usually directly uses the spot test line to connect the comprehensive tester to the spot test hole of the mobile terminal and then test. Since the millimeter wave is an antenna array plus multi-channel transceiver signals, the traditional conduction test cannot be applied. [00...
