ABSTRACT:
A customizable impedance matching network for coupling a microwave transmission line to an FET. The network includes a plurality of conductive pads formed on the first surface of a dielectric substrate each pad providing in combination with the substrate and a conductor formed on an opposite surface of the substrate, a predetermined capacitance. Selective ones of such conductive pads are interconnected in parallel to form a capacitor having a capacitance related to the total surface area of such interconnected conductive pads, to provide the requisite capacitive reactance for the network. The network further includes a strip conductor formed on such first surface having a predetermined inductance per unit length and having a first end electrically connected to the network. A first end of a selected length of bonding wire is attached to such strip conductor at a bonding point between the ends of such strip conductor to provide an inductor having an inductance related to the sum of the lengths of the bonding wire and the length of the strip conductor between the bonding point and the first end of such strip conductor. Such inductor provides the requisite inductive reactance for the network. Alternatively, the requisite inductive reactance may be provided by a second plurality of conductive pads formed on such first surface selectively interconnected together with selected lengths of bonding wire. The inductance of such inductor is related to the total length of such bonding wire.
