Abstract :
A proper analysis of the assembly influence on small-signal parameters of packaged transistor has been done. The S-parameters differences caused by assembly change are computed using the standard method and three new proposed methods that exploit 3-D model of the transistor package. The differences, accuracy and suitability of these methods are discussed. The results were verified experimentally for particular packaged transistor in frequency range 45 MHz-18 GHz.
