RF switch is a key component of the wireless communication system, and its performance determines the key performance of electronic products, which is a direct factor affecting the stability and reliability of the system.In this paper,the frequency range of the matrix switch assembly is 30~3 000 MHz,and the matrix switch assembly includes a total of 10 inputs and two outputs.Input ports are divided into five groups,receiving signals from the five pairs of antennas,and power to the antenna through the input interface. The switching module uses the structure of two parts on the plug,by switching the output between the five input packets. and the pathway is controlled by complex programmable logic device(CPLD) program. Test results show that the matrix switching module has excellent performance of good opening phase, amplitude uniformity, high isolation, low VSWR,high switching speed. It is easy to the test and optimization of each part.
