ABSTRACT:
An impedance matching network for coupling a microwave transmission line to a field effect transistor (FET). The impedance matching network includes a resistor coupled in shunt with the FET and an inductor connected between the microwave transmission line and the resistor. The inductor is formed by wrapping a conductive wire around a post inserted into a hole formed in a support for the FET.
