Abstract

High density MCM(Multi Chip Module) design is the direction of microwave circuit and system. In the study of frequency transformation module,when both signals are input simultaneously, the off-band signal affects the in-band gain.The possible causes of the gain subsidence at individual frequencies were comprehensively analyzed and verified.The mixer’s output signal has multiple frequencies. The test proves that adding a low-pass filter after the mixer is effective. It and the subsequent circuit amplification and band pass filter constitute an effective frequency selection and amplification network.The problem is solved, and the performance specification of the module is improved to meet the design requirements. The influence of these characteristics should be concerned in advance in the practice of broadband chip amplifier, and similar corresponding measures should be added in the design of MCM module.
