ABSTRACT:
The present amplifier has a pair of semiconductor amplifiers, and the input signal is divided to said amplifiers, the outputs of which are combined together by the power combiner. At least one of the power divider and the power combiner has a plurality of circulators which have three terminals. The characteristic impedance of one terminal is 2Z.sub.O and that of another terminals is Z.sub.O. Thus, by connecting the terminals of the characteristic impedance 2Z.sub.O of two circulators, the resultant characteristic impedance Z.sub.O is obtained and can be connected to an external circuit directly.
The present amplifier can be utilized in particular in VHF or higher frequency band.
