While todays MMIC chips suffer from lack of tuning ability, millimeter and microwave communication applications face a demand for very high MMIC performance.  At the chip level this calls for wide band, high overall gain, return loss, output power, and low noise.  The proposed concept of re-configurable MMIC (RMMIC) will reduce cost/performance of highly integrated circuits by providing tuning ability to the chip components.  RMMIC is a traditional MMIC upgraded with special elements that allow adjusting the essential circuit parameters after the wafer manufacturing is finished.  The circuit adjustment is realized at the wafer level and “survives” through the rest of the circuit lifetime with no additional power consumption.
