摘要： An internal operation of RF IC is adjusted so that the level of an RF transmitter signal is substantially stopped from rising, or made to descend in course of ramp-up of the RF transmitter signal. This adjustment is enabled by ramp-up adjustment data Last 4 symbols contained in preamble data precedent to real transmission data transmitted after completion of ramp-up. The ramp-up adjustment data and real transmission data are supplied from a baseband LSI. The RF transmitter signal contains phase and amplitude modulation components according to the EDGE system. RF IC includes phase and amplitude modulation control loops PM LP and AM LP. Ramp-up of RF power amplifiers PA1 and PA2 is performed by controlling the gain of the first variable amplifier MVGA included in the AM LP according to ramp information. Thus, unwanted radiation's level is reduced during ramp-up of the RF transmitter signal of the RF power amplifiers.

摘要： A transmitter that can reduce noise without using an SAW filter whose IC integration is hard, and copes with two modulation formats of constant envelope modulation and non-constant envelope modulation, and a downsized and low-cost wireless communication apparatus that uses the transmitter are provided. The transmitter includes a quadrature modulator that modulates an input signal by quadrature modulation, a first amplifier that amplifies a modulation signal outputted by the quadrature modulator, and a second amplifier that amplifies an output signal of the first amplifier. The first amplifier operates as a limiter when the modulation format is the constant envelope modulation, and performs linear operation when the modulation format is the non-constant envelope modulation.
