Patent ID: 7363014

Claim:
A transmitting apparatus comprising: a transmission power amplification section that has a high-frequency power amplifier that performs power amplification of a transmit signal to output that signal; and a compensation section that performs compensation of average output power of said high-frequency power amplifier; wherein: said transmission power amplification section has a first mode in which said high-frequency power amplifier is operated as a nonlinear amplifier and amplitude modulation of said transmit signal and control of an average output level of said transmit signal are performed based on a power supply voltage of said high-frequency power amplifier, and a second mode in which said high-frequency power amplifier is operated as a linear amplifier and amplitude modulation of said transmit signal and control of said average output level of said transmit signal are performed in a stage prior to said high-frequency power amplifier; and said compensation section has a compensation table that stores compensation value information for compensating said average output level, and compensates said average output level based on said compensation value information stored in said compensation table.
