Simplified radio frequency switch matrix circuit system

The invention relates to the technical field of radio frequency microwaves, in particular to a simplified radio frequency switch matrix circuit system which comprises a first radio frequency switch and a second radio frequency switch which are single-pole multi-throw switches, and the output end of each of the first radio frequency switch and the second radio frequency switch comprises a first port and more than two second ports. When the system is not electrified, the input ends of the first radio frequency switch and the second radio frequency switch are respectively communicated with the respective first ports and are not communicated with the second ports; and when the system is powered on, the input ends of the first radio frequency switch and the second radio frequency switch are respectively gated with the respective second ports and are disconnected from the first port. Only two radio frequency switches and a corresponding number of cable assemblies are needed, a channel selection function which can b
