Abstract
A microwave signal amplifier comprising transistor having input and output terminals further includes input and output matching circuits connected to the input and output terminals, respectively, and corresponding bias supply circuits connected in parallel between said transistor and said input and output matching circuits, respectively. The input and output matching circuits are each implemented by high pass filters, and the bias supply circuits are each implemented by low pass filters. Furthermore, said high pass and low pass filters respectively have capacitors and inductors connected to the transistor, and said low pass filters have termination resistors.
