Active Harmonic 5G Tuners

Harmonic multi‐probe tuners control independently two (MPT‐Lite) and three (MPT) harmonic frequencies. However insertion loss between the tuner and the DUT, especially at 5G (28‐36GHz) frequencies, limit the tuning range and the capacity of the tuners to test some devices.

This shortcoming is reversed using the Hybrid Harmonic Tuner concept* (MPT+). A feed‐forward active loop is added to the multi‐carriage tuner and allows reflection factor at DUT reference plane |Γ DUT| =1.
