A Test Scheme for Broadband T/R Module Based on SiP

This paper puts forward and verifies a scheme to repeatedly and efficiently test wideband T/R module based on system-in-package(SiP) with a non-coaxial package. The proposed test fixture consists of a test socket and test printed circuit board (PCB). The test socket with coaxial elastic probes plays an important role in realizing the interconnection between T/R module and test PCB, which fabricated on Rogers 4350 substrate. A broadband T/R module based on SiP is selected for verification and the test result shows the feasibility of the test scheme. All in all, this paper successfully proposes, characterizes, and verifies a test scheme for the wideband T/R module based on SiP.
