摘要： A transmission circuit is capable of precisely compensating for an offset characteristic of an amplitude modulation section, and operating with low distortion and high efficiency over a wide output electric power range. A signal generation section outputs an amplitude signal and an angle modulation signal. An amplitude amplifying section inputs, to the amplitude modulation section, a signal corresponding to a magnitude of the amplitude signal having been inputted. The amplitude modulation section amplitude-modulates the angle modulation signal with the signal inputted from the amplitude amplifying section, and outputs a resultant signal as a modulation signal. The power measuring section measures an output power of the amplitude modulation section. An offset compensation section reads an offset compensation value from a memory in accordance with the output power of the amplitude modulation section, and adds the read offset compensation value to the amplitude signal.

摘要： 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.

摘要： A power amplifier capable of compensating for distortion by pre-distortion and achieving a large distortion suppressing effect even if IM3L components and IM3U components occurring at the power amplifier have a large level difference. A power amplifying circuit 117 amplifies an original signal. An envelope detector 119 generates an envelope signal having components identical to envelope components included in the original signal. Based on the original signal a distortion signal generating circuit 112 generates a distortion signal for canceling distortion components occurring while the original signal is amplified by the power amplifying circuit 117. In a power combiner 116, the envelope signal is injected to the original signal, thereby eliminating the asymmetric characteristic of the distortion components. In the power amplifying circuit 117, the distortion signal is injected to the original signal, thereby suppressing the distortion components.

摘要： A semiconductor device includes: a semiconductor substrate in which a semiconductor element is formed; a multilayer structured wiring layer that is provided on the semiconductor substrate, the wiring layer forming a structure connected with the semiconductor element; a spiral inductor that is formed in at least one layer of the wiring layer; and a connection terminal formed in an uppermost layer of the wiring layer for establishing connection from the wiring layer to an outside such as a printed board. A shielding wiring pattern is disposed between the spiral inductor and the connection terminal, the shielding wiring pattern functioning as an electromagnetic shield for the uppermost layer of the wiring layer. The shielding wiring pattern absorbs a change in electrical field caused by a potential change in the connection terminal, providing a shielding structure which suppresses the superposing of noise and an unnecessary signal onto the spiral inductor from the connection terminal.

摘要： A multicarrier transmitting method that includes inputting n input signals, generating carriers corresponding to the n input signals, modulating the carriers into n modulated signals and generating at least one additional signal having a frequency outside band of the n modulated signals. The method also includes adjusting a level and a phase of the generated additional signal, outputting a multiplexed signal by adding up the n modulated signals and the adjusted additional signal, amplifying the multiplexed signal, and then removing the additional signal. The level and the phase of the additional signal are adjusted such that, after predicting a change of a composite vector of the n modulated signals based on an amplitude and a phase of the n carriers, a composite vector obtained after an adding operation can be lower than that before the adding operation when an absolute value of a prediction result exceeds a predetermined level.
