Abstract

This application discloses a radio frequency circuit debugging method and related products, which are applied to debugging radio frequency circuits. The radio frequency circuit includes radio frequency transceivers, PAs, duplexers, filters, main set switches and main set antennas. PA, duplexer, main set switch and main set antenna transmit radio frequency signals, and the radio frequency transceiver receives radio frequency signals through the main set antenna, main set switch, duplexer and filter in turn, the method includes: extracting through the printed circuit board PCB The circuit parameters between the main set switch and the main set antenna; through the simulation software and circuit parameters, the target scattering parameters of the output end of the main set switch are obtained; through the simulation software and the target scattering parameters, the main set switch and the main set are obtained A first matching parameter of a matching circuit between antennas. The simulation efficiency can be improved by adopting the embodiment of the present application.

Description

technical field [0001] The present application relates to the field of simulation technology, in particular to a radio frequency circuit debugging method and related products. Background technique [0002] The third-generation mobile communication technology (3rd-Generation, 3G) communication and the fourth-generation mobile communication technology (the 4th Generation, 4G) communication of electronic devices (such as smart phones, etc.) are mainly divided into frequency division duplexing (frequency division duplexing, FDD) ) and time division duplexing (time division duplexing, TDD) two communication modes, in which the FDD transceiver channel mainly realizes the simultaneous operation of the transceiver through the duplexer without interfering with each other. During the debugging process, it is often necessary to optimize the matching of the common end of the duplexer to optimize the RF performance of the corresponding FDD frequency band. The conventional method is to u...
