ABSTRACT:
An input signal specified by an input frequency is divided by an out-of-phase type input hybrid coupler, into two divided signals with regard to the power of the input signal, where the divided signals have different phases. The input frequency of each of the divided signals is multiplied by a frequency multiplier connected with the input hybrid coupler, producing frequency multiplied signals each specified by the multiplied frequency. The frequency multiplied signals are composed by an out-of-phase type output hybrid coupler with regard to power, producing an output signal specified by the multiplied frequency. A phase shifter is provided between the input and the output hybrid coupler for varying the phase difference between the frequency multiplied signals, so that the frequency multiplied signals are composed in in-phase.
