✦ Synopsis

For design and characterization of packaged RF-band transistor amplifiers, test fixtures consisting of coaxial connectors and planar-type transmission lines are frequently used. We present a method of extracting 3D field simulation parameters of these test fixtures and demonstrate that a circuit model of the test fixtures can be constructed by pure 3D field simulation using the extracted material constants. The developed circuit model predicts measurement results within 0.5 dB.
