Abstract: A transmission circuit switches a bias circuit without allowing a power amplifier to enter a non-bias state. A first bias circuit supplies a first bias signal to a power amplifier, and a second bias circuit supplies a second bias signal to the power amplifier. A first delay circuit delays the switching of an operation of the first bias circuit using a first delay time, and a second delay circuit delays the switching of an operation of the second bias circuit using a second delay time. The first bias circuit and the second bias circuit are both simultaneously operated for a predefined time period, in order to prevent a transistor for amplification from entering a non-bias state when switching an operation mode of the power amplifier.

Abstract: A transmission modulation apparatus capable of dealing with characteristic variations of a high-frequency power amplifier without always forming an amplitude loop. Transmission modulation apparatus 100 is configured with level detector 140 that receives input of a level detection control signal and detects the output signal of high-frequency power amplifier 130, and offset voltage correcting section 150 that corrects an offset voltage using collinear approximation including a first point where the relationship between the power supply voltage value and the output voltage starts to shift from linear to non-linear based on an output signal of level detector 140 and a second point where output voltage is a minimum. Offset voltage correction is adaptively executed, and linearity between the voltage value of the baseband amplitude signal and the output voltage of high-frequency power amplifier 130 when the voltage value of the baseband amplitude signal is low is compensated.

Abstract: A transmission circuit is provided which can quickly and accurately control an output power of a transmission signal even when the transmission signal is output at a high modulation rate and in a wide dynamic range. A switching control section controls a modulation method changing section to change a modulation method of a modulated signal generating section to a modulation method having a narrow dynamic range before controlling a switching section to switch amplification sections. An output adjustment control section controls output adjusting sections so that a difference in level between a transmission signal which is smoothed by a smoothing circuit and is before the amplification sections are switched, and a transmission signal which is after the amplification sections are switched, is caused to be smaller than a predetermined difference threshold value, when the modulated signal generating section operates in the modulation method having the narrow dynamic range.
