摘要： A power amplification apparatus generates a code for controlling the number of class D power amplifiers that are in operation among a plurality of class D power amplifiers, changes the duty ratio of a carrier wave signal in accordance with output voltage, and amplifies a transmission signal. A code for decreasing the number of class D power amplifiers in operation is generated when the duty ratio of the carrier wave signal is increased, while a code for increasing the number of class D power amplifiers in operation is generated when the duty ratio of the carrier wave signal is decreased.

摘要： A transmitting apparatus and transmission method are capable of easily and correctly mixing an in-phase component and a quadrature-phase component in a quadrature modulator. A local signal with a duty ratio of 25% or smaller is generated without using frequency which is a multiple of frequency of the local signal. Without providing switches in series to the outputs of I and Q amplifiers, a duty ratio of 25% or less is obtained. for the local signal, and class-D unit amplifiers are operated such that one of the I amplifier and the Q amplifier is connected to the output side in any state regardless of whether an output power control signal is at an on-level or an off-level. In producing the 25% duty ratio, a local signal with a 50% duty ratio is converted so as to have a duty ratio of 25% by I and Q duty converters.
