Abstract :
This paper presents the design of Monolithic Six-Port Module MSPM with resistive bridges. It shows how these simple structures may act as directional resistive couplers. Final MMIC circuit includes six-port junction and matched MESFET detectors covering an area of 1.2 mm2 in the frequency range 100 MHz to 3 GHz. The MSPM was bonded in a MIC structure with output coaxial connectors or inside the tips of a probe station. In this last case, the MSPM acts as an active probe. Experimental results obtained using a commercial network analyzer and our measurement system are in good agreement.
