摘要： Provided is a transmission circuit 1 which precisely compensates for an offset characteristic of an amplitude modulation section 15 and which operates with low distortion and high efficiency over a wide output power range. A signal generation section 11 outputs an amplitude signal and an angle-modulated signal. An amplitude amplifying section 14 supplies, to the amplitude modulation section 15, a voltage corresponding to a magnitude of an inputted amplitude signal. The amplitude modulation section 15 amplitude-modulates the angle-modulated signal by the voltage supplied from the amplitude amplifying section 14, thereby outputting a resultant signal as a modulation signal. A temperature measuring section measures a temperature of the amplitude modulation section 15. An offset compensation section 12 calculates an offset compensation value in accordance with a change, in temperature of the amplitude modulation section 15, from the temperature of the amplitude modulation section 15 in an initial state, and adds the calculated offset compensation value to the amplitude signal.

摘要： A small-size transmission circuit is provided which outputs a transmission signal having high linearity independently of a magnitude of an output power, and operates with high efficiency. A signal generating section generates quadrature data based on input data. A computation section compares an amplitude component of the quadrature data with a predetermined amplitude threshold value, and outputs an amplitude signal, a first phase signal, and a second phase signal. A regulator outputs a voltage controlled depending on the amplitude signal. An angle modulation section and an angle modulation section angle-modulate the phase signal to output first and second angle-modulated signals. An amplitude modulation section and an amplitude modulation section amplitude-modulate the first and second angle-modulated signals using a voltage controlled depending on the amplitude signal to output the angle-modulated and amplitude-modulated signals as a first modulated signal and a second modulated signal. A combining section combines the first and second modulated signals to output a transmission signal.

摘要： An amplitude frequency characteristic adjustment circuit 106 is provided downstream of and connected to a distortion generation circuit 105. An amplitude difference between low-frequency-side and high-frequency-side distortion voltages is adjusted by the amplitude frequency characteristic adjustment circuit 106, and then their amplitudes and phases are adjusted by a vector adjustment circuit 107. This configuration makes it possible to suppress simultaneously both of low-frequency-side and high-frequency-side distortion voltages of a distortion generated by a wide-band class-AB power amplifier even if they are different in amplitude and phase.

摘要： A delay circuit in which amplitude characteristic and delay time characteristic of the output signals do not have any ripple relative to the length of the transmission line is provided. The delay circuit includes a circuit that makes a part of signals distributed into two parts by the power divider (103) to be identical in amplitude and inverse in phase relative to the component of signals outputted from the terminal-a directly to the terminal-c of the circulator (104). By composing with the power combiner (107) both signals are offset each other at the output terminal. As a result, only the signals that are inputted from the input terminal (101) and transmitted through the circulator (104) and the open-ended transmission line (105) are outputted to the output terminal (102).
