Abstract :
The monolithic microwave IC (MMIC) approach for the front end of an RF spectrum analyzer improves interconnection problems due to direct access to a device-under-test (DUT). This paper proposes and demonstrates novel MMIC´s for a probe-type, 1-32 GHz spectrum analyzer (SPA) front end. The MMIC´s are an up-converter, a variable attenuator, a switch, and a down-converter. This MMIC set utilizes novel FET cells for impedance matching, signal combinations, isolation, and impedance translation to achieve an ultra-wideband performance as well as a remarkable size reduction in an SPA front end
