Abstract
The present invention discloses a harmonic reflective tuner system consisting of a radio-frequency (RF) or microwave transmission line having a longitudinal axis, containing two harmonic resonators sliding on the central conductor, where the harmonic resonators are comprising a pair of identical RF slugs, mechanically attached together. The two harmonic resonators will reflect two harmonic frequencies of a base frequency F0. The harmonic reflective tuner of this invention has an input and output, said input being connected to the DUT trough a diplexer in parallel with the fundamental tuner.
Claims4
An electromechanical harmonic reflective tuner having an input and an output, comprising a transmission line with longitudinal axis, in which two harmonic resonators are sliding along said transmission line by means of electrical remote control, each of said harmonic resonators are comprising 2 identical wide band RF slugs longitudinally spaced apart win a fixed longitudinal distance identical to said wide band RF slugs longitudinal lengths, first harmonic resonator being transparent to the maximum VSWR resonant frequency of the second harmonic resonator.
