Abstract
There are disclosed impedance matching networks and technique for impedance matching to microwave power transistors. Distributed capacitor inductor networks are used so as to provide a high degree of control and accuracy, especially in terms of inductance values, in comparison to existing lumped capacitor arrangements. The use of bond wires is reduced, with inductance being provided primarily by microstrip transmission lines on the capacitors.
