Abstract
Pre-matching of distributed push-pull and power transistors enabling the effective use of high-power and high-frequency transistor arrays. In accordance with the invention, a pre-matching element is connected between stages of multi-transistor arrays. The pre-matching element serves to transform the impedance at a connecting point between stages toward an impedance level that is less sensitive to transmission line losses. In one embodiment of the invention the pre-matching element is a shunt inductor.
