Abstract:
A method of manufacturing a power transistor circuit, comprising carrying out the following steps in the enumerated order:(1) providing a substrate, said substrate comprising a pre-assembled power transistor circuit including a die secured to said substrate comprising a transistor having an input terminal, at least one input matching element and at least one input signal lead; (2) measuring a performance characteristic of the transistor before connecting the transistor with the input matching element and input signal lead by means of a test network comprising connections with known inductances; (3) using one or more wires to electrically couple the transistor input terminal to an input matching element, an input signal lead, or both; and (4) setting the impedance of the one or more wires based at least in part on the measured transistor performance characteristic from step (2).
