摘要： To provide a multiband-support radio-frequency module in which the occurrence of a harmonic signal in an amplifier circuit is suppressed and the output of a radio-frequency signal containing unwanted harmonic components is prevented. A first signal path SL1 and a second signal path SL2 are provided such that they intersect each other at least once in a multilayer substrate 2, as viewed from above. With this configuration, high-output radio-frequency signals output from a first amplifier circuit 31 and a second amplifier circuit 32 can be prevented from interfering with other elements disposed in the multilayer substrate 2. It is thus possible to provide a multiband-support radio-frequency module 1 exhibiting excellent RF characteristics by suppressing the occurrence of harmonic signals in each of the first and second amplifier circuits 31 and 32 and by preventing the output of radio-frequency signals containing unwanted harmonic components.

摘要： A transmitter in a wireless communication system is provided. The transmitter includes a baseband signal processor for detecting an envelope signal, a supply modulator (SM) for producing power to be supplied to a power amplifier using the detected envelope signal, and the power amplifier for receiving voltage from the SM and for amplifying power of a transmit signal. The SM generates a compensation signal corresponding to switching noise generated via switching amplification, and adds the compensation signal and the switching noise. The amplifier of the wireless communication system can produce low switching noise, and the envelope tracking power amplifier can prevent reception degradation due to the noise of the supply modulator.

摘要： The invention provides a semiconductor integrated circuit device and a high-frequency power amplifier module capable of reducing variations in the transmission power characteristics. The semiconductor integrated circuit device and the high-frequency power amplifier module each include, for example, a bandgap reference circuit, a regulator circuit, and a reference-voltage correction circuit which is provided between the bandgap reference circuit and the regulator circuit and which includes a unity gain buffer. The reference-voltage correction circuit corrects variations in a bandgap voltage from the bandgap reference circuit. The reference-voltage correction circuit includes first to third resistance paths having mutually different resistance values, and corrects the variations by selectively supplying a current which reflects an output voltage of the unity gain buffer to any one of the first to third resistance paths. The selection in this case is performed by connecting a bonding wire to any one of the terminals REF1 to REF3.

摘要： A first signal path has one or a plurality of coils arranged in series, the coils being connected to the output of a first amplifier. A second signal path has the same number of coils as the coils of the first signal path, the coils being arranged in series and connected to the output of a second amplifier. Coupling paths have capacitors and couple the first signal path and the second signal path at both ends of the corresponding coils on the first signal path and the second signal path. A SW controlling unit switches a switch to a contact when a signal is input from the first amplifier and switches the switch to a contact when a signal is input from the second amplifier.

摘要： An amplification transistor has a collector to which a voltage converted by a DC/DC converter is supplied. An output voltage of the DC/DC converter is determined based on an input impedance of a rear-stage circuit block. For example, a voltage of the DC/DC converter is set such that an output waveform of an amplifier circuit becomes appropriate for the input impedance of the rear-stage circuit block (generally 50 [Ω]) in a targeted modulation scheme (mode) or frequency (band) to be used, without having to use an output matching circuit.
