Abstract: PROBLEM TO BE SOLVED: To provide a transmission circuit capable of operating in low distortion and high efficiency even in a modulation system using a wide band. SOLUTION: A signal generation section 11 generates an amplitude signal M and an angle-modulated signal Sθ. An adaptive compensation filter 12 performs waveform shaping processing for the amplitude signal M in accordance with a magnitude of the amplitude signal M. An amplitude amplification section 14 outputs a signal proportional to a magnitude of the signal subjected to waveform shaping in the adaptive compensation filter 12. An amplitude modulation section 15 amplitude-modulates the angle-modulated signal by the signal outputted from the amplitude amplification section 14 and outputs the resulting signal as a modulated signal. The characteristics of the adaptive compensation filter 12 are inverse characteristics of transfer characteristics between the input of the amplitude amplification section 14 and the output of the amplitude modulation section 15.

Abstract: PROBLEM TO BE SOLVED: To provide a transmission circuit operating with high linearity and with low noise.
SOLUTION: An AM variable fc filter 102 uses an AM cutoff frequency to remove a high frequency component from an amplitude signal. An amplifier 105 supplies a power amplifier 107 with a voltage which is a result of amplifying the amplitude signal output from the AM variable fc filter 102. A PM variable fc filter 103 uses a PM cutoff frequency to remove a high frequency component from a phase signal. A phase modulator 104 phase-modulates the phase signal output from the PM variable fc filter 103 to output a high-frequency phase-modulated signal. The power amplifier 107 amplifies the high-frequency phase-modulated signal by using the voltage supplied from the amplifier 105, and outputs a resultant signal as a transmission signal. The AM variable fc filter 102 and the PM variable fc filter 103 respectively control the AM cutoff frequency and the PM cutoff frequency such that the AM cutoff frequency and the PM cutoff frequency each have an opposite characteristic to that of an output power of the transmission signal.
