Microwave probe comparison using an interface inductance benchmark

In this work we compare the performance of a number of microwave Ground-Signal-Ground probe designs for the case of a test device that causes asymmetric ground currents. An interface inductance benchmark first proposed in [1] is used to quantify the different behavior of three different probe designs. A simple one-port inductor measurement shows the impact on measurement accuracy for the various probe designs and serves to demonstrate the accuracy of the interface inductance model proposed in [1].
