TECHNIQUES FOR THE INTEGRATION OF HIGH-Q MILLIMETER-WAVE FILTERS IN MULTI-FUNCTION MMIC MODULES

摘要

There has been a widespread trend toward higher levels of integration in microwave and millimeter-wave system design, motivated by a desire to reduce cost, size and complexity, particularly as many old applications are being re-invented in array architectures. The most commonly used format for achieving high levels of integration in millimeter-wave systems is the MMIC-based multi-function module (MFM). High performance MMIC circuits of all kinds up to about 50 GHz are already readily available at low cost from many commercial suppliers. The selection of commercial MMICs above 50 GHz is more limited, however, although new ones are introduced regularly, and foundry services for Ⅲ-Ⅴ semiconductors are provided by many companies that enable users to design their own custom chips for applications well over 100 GHz.
