Abstract

The invention discloses a system for realizing radio frequency switch spurious testing, including a duplexer, a radio frequency switch, a signal source and a spectrum analyzer, wherein the duplexer transmits the transmission signal output by the signal source to the radio frequency switch, and the radio frequency switch When the switch state is switched, a reflected signal is generated according to the transmitted signal, and the reflected signal is transmitted to the spectrum analyzer by the duplexer. The spectrum analyzer tests the spur generated by the RF switch when the switch state is switched according to the reflected signal. By using a duplexer with a spectrum analyzer and a signal source to test the spurs generated by the RF switch when the switch state is switched, there is no need to use other special equipment for testing spurs. The system structure is simple and easy to build, which is convenient for technicians to test the RF switch. stray.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a system for realizing spurious testing of radio frequency switches. Background technique [0002] In the mobile communication base station system, the duplexer is an indispensable functional module. The ANT port (antenna end) of the duplexer will be connected to the antenna feed system (including TMA, current injector and antenna) that radiates electromagnetic waves to the surrounding space. Wait). In the connection between the antenna feeder system and the duplexer, the two microwave modules, the impedance between the two modules cannot be completely matched, and there are more or less energy reflections at the interface. When the antenna system is seriously mismatched, that is, the effective transmission power is too little and the reflection power is too much, many modules in the base station system, especially the power amplifier, are easily damaged, affecting the nor...
