The ecad radio frequency amplifier which has low the loss, asymmetric combiner, and asymmetric combiner for the phase difference system

摘要

Combiner did not have the output resistor, the output joining consent was arranged asymmetrically vis-a-vis two input edges of combiner, one for the phase difference system loss combiner is offered low. It is the kind of place where combiner has the input impedance which is suited for the input signal of the combiner which of the concretely, as for the position, accompanies the mutual phase difference wide range. This input impedance, profitably, has very small reactive component. Furthermore, as phase difference between the input signals of combiner increases, the real part of input impedance increases. Furthermore, in the form which responds to the amplitude of the input signal, the input signal being expanded by the active divider, it is divided into the 1st and 2nd signal which accompanies mutual phase difference, (ecad) the RP amplifier is disclosed desirably. Two signals are combined after the further expanding, for the second time low by loss combiner.
