Hybrid Split Signal Load Pull System / 14/564,396

Tuesday, December 9, 2014

A split signal hybrid, fundamental and harmonic frequency, active injection load pull setup includes a harmonic receiver, impedance tuners and operates using only a single power source at the fundamental frequency Fo and a single power amplifier. Wideband and harmonic impedance tuners serve for pre-matching the DUT and reducing the injection power requirement, as well as building programmable both wideband and harmonic adjustable attenuators and phase shifters in the power injection (feedback) loop.
