COMPENSATION FOR PARASITIC COUPLING BETWEEN RF OR MICROWAVE TRANSISTORS IN THE SAME PACKAGE

摘要

Parasitic coupling effects between RF or microwave transistors provided in a common package are compensated by connecting one or more capacitors between the transistors. By connecting the capacitor(s) at a location that corresponds to the site of the coupling, the compensation is effective over a wide frequency band. This coupling-compensation makes it feasible to provide, in a common package, RF or microwave transistors intended to operate in quadrature, thereby improving performance matching and operating efficiency of the overall device.
