とするリニアライザ。 A branching 3dB coupler that equally divides the input signal into two, a variable attenuator that attenuates the divided signal to a specified level, and a distortion generating amplifier that receives the signal from the variable attenuator and amplifies it to generate distortion. an attenuator that changes only the level without changing the amount of distortion of the distortion generating amplifier; a phase shifter that adjusts the phase of one of the signals distributed by the branch 3bB coupler; and a signal on the side of the distortion generating amplifier. Synthesis 3 to combine the signals on the phase shifter side above
A linearizer comprising a dB coupler and an attenuator that attenuates the signal from the composite 3 dB coupler to the input level of a high-output amplifier provided afterwards.
