IPC: H03F3/193
Filed: 1989-12-27
Abstract: PURPOSE:To equivalently short-circuit a double wave without fail by taking-out one part of a fundamental wave signal to be inputted to a semiconductor amplifier, converting this signal to a double wave signal, inverting the phase of the signal to that of the double wave signal to be outputted from the semiconductor amplifier and impressing the signal to the output side of the semiconductor amplifier. CONSTITUTION:One part of the fundamental wave input signal is supplied to an amplifier 7. The fundamental wave signal amplified by the amplifier 7 is changed to the double wave signal by a multiplier 8. The double wave signal generated by the multiplier 8 is adjusted by a band pass filter 9 and a phase shifter 10 so as to obtain the inverse phase and the same amplitude as the double wave signal generated in a drain terminal 5 of an FET 3, and supplied to the drain terminal 5. In the drain terminal 5, the double wave signal generated in this drain terminal 5 is canceled by the double wave signal with the inverse phase and the same amplitude and the double wave is equivalently short-cirucited. Accordingly, operation is executed with high efficiency.
