Abstract

There is provided a transmission circuit capable of obtaining an output signal having less distortion with high power efficiency while assuring a dynamic range of the transmission power control. In the transmission circuit (100), when a “low output mode” cycle in which the output level (transmission power) of a signal output from a synthesizer (160) is a small, two power amplifiers (140, 150) are operated as orthogonal modulation amplifiers that linearly amplify an orthogonal modulation signal output from an orthogonal modulation unit (112). When a “high output mode” cycle in which the transmission power is large, the two power amplifiers (140, 150) are operated as LINC amplifiers that non-linearly amplify a constant envelope signal output from a constant envelope signal generation unit (111) by using an LINC method. This makes it possible to obtain the output signal having less distortion with high power efficiency while assuring a dynamic range of the transmission power control, thereby obtaining the transmission circuit having a low power consumption, a high efficiency, a small size, and a high dynamic range at a low cost.
