ABSTRACT:
The present invention discloses a harmonic rejection tuner system consisting of a radio-frequency (RF) or microwave transmission line having a longitudinal axis, containing at least one harmonic resonator sliding on the central conductor, said harmonic resonator is a pair of shorted-stubs, said shorts are adjustable, making the electromagnetic length of the shunt shorted-stubs variable, therefore making the resonant frequency of the harmonic resonator variable. The harmonic resonator will reflect a harmonic frequency nF0of a base frequency F0. The harmonic rejection tuner of this invention has an input and output, and is connected in series between the DUT and the large band fundamental tuner.
