Abstract: 

This invention relates to the reduction of insertion losses and by consequence maximization of reflection factors for on-wafer load pull testing of high power or low noise transistor chips, using as much a direct integration as possible between the slotted airline of the tuners and low loss probes, said probes being either modified commercial probes or probes made as an extension of the tuner slotted airline itself.
