摘要： The present invention provides a transmitter which performs matching between parts, corresponding to switching between bands for transmission signals and performs more suitable matching in response to unintended changes in device characteristics inside the parts due to secular changes or the like, and etc. The transmitter includes matching circuits coupled to the input and output sides of each amplifier, and level detectors each of which inputs therein the amplified transmission signal via the matching circuit and detects the level of the transmission signal. When one is selected from a plurality of transmission bands to generate a transmission signal, the transmitter sets the value of impedance corresponding to the transmission band to the corresponding matching circuit and fine-adjusts the set value of impedance, based on the result of detection by the corresponding level detector after the setting of the value of the impedance thereto.

摘要： A high frequency circuit and a high frequency module are provided, in which the accuracy of compensation operation is improved in compensating by digital control. The amplification gain of an amplification element of an amplifier unit is controlled by a bias current of a bias control unit. A process monitoring circuit of a calibration circuit includes a first and a second element characteristic detector and a voltage comparator. The detectors convert the current of replica elements into a first and a second detection voltage. The voltage comparator compares a first and a second detection voltage and supplies a comparison output signal to a search control unit. Responding to the comparison output signal of the comparator and a clock signal of a clock generating unit, the controller generates a multi-bit digital compensation value according to a predetermined search algorithm, and the bias control unit of the second detector is feedback-controlled.
