Design of Broadband T/R Module Based on LTCC Multi-layer Substrate Technology

This paper introduces the design of a broadband transmitting/receiving(T/R) module based on low temperature co-fire ceramic(LTCC) multi-layer substrate technics,discusses the circuit layout and assembly technics of the module,presents specific test data.The volume of T/R module is 65 mm×29 mm×9 mm,the output power of continuous wave is more than 25 W,the phase shift error of root mean square is less than 3°,which satisfies the requirement of engineering application.
