Abstract：The paper addresses the recurrent issue offrequent changes in RFcables during the debugging process ofcomplex electronic equipment.To tackle this challnge，a multi-channel programmable radio frequency routing matrix （hereafterreferredtoas theRFmatrix）has been designed.This innovative solutionaims toofferahighlevel of programmability，enabling flexible path configurations，therebymarkedlyenhancingboth debugging eficiency and userconvenience when utilizing the device.This paper outlines the comprehensive design strategy forthe multichannel programmable radio frequency routing matrix meticulously，elucidating itsoperational mechanism，circuit architecture，and delving into specific designapproaches for pivotal components suchas the digitalcontrol module， radio frequency routing unit，and thermal management systems.

Keywords：multi-channel; digital programming;radio frequency unit
