摘要： A method of controlling a feedforward distortion compensation amplifier has steps of
detecting a distortion component generated in a main amplifier by coupling a signal branched from a signal input to the main amplifier and containing a plurality of carriers of different frequencies to a signal branched from an output signal from the main amplifier so that the coupling causes the carrier components to cancel each other,
recoupling the signal resulting from the coupling to the output signal from the main amplifier,
and adjusting an amplitude and phase of at least one of the signals to be recoupled so that distortion components cancel each other upon recoupling,
wherein a first and second pilot signals obtained from a first and second pilot signal sources are inserted into the input signal to or output signal from the main amplifier, parts of the signal resulting from the recoupling are taken out through branching, and the signals taken out through branching are mixed with the first and second pilot signals, respectively, and thus down-converted to generate down convert signals so that control signals to adjust the amplitude and phase are generated according to the down convert signals.摘要翻译： 控制前馈失真补偿放大器的方法具有以下步骤：通过将从信号输入分支到主放大器并且包含多个不同频率的载波的信号耦合来检测在主放大器中产生的失真分量， 从主放大器的输出信号分支的信号，使得耦合使载体分量彼此抵消，将从耦合到由主放大器的输出信号产生的信号重新耦合，€ƒ€ 并且调整待重新耦合的至少一个信号的振幅和相位，使得失真分量在重新耦合时彼此抵消，其中从第一和第二导频信号源获得的第一和第二导频信号 被插入到主放大器的输入信号或输出信号，通过分支取出由重新耦合产生的信号的部分，并且s 通过分支取出的点火分别与第一和第二导频信号混合，并因此下变频以产生下变频信号，从而根据降频转换信号产生调节幅度和相位的控制信号。

摘要： A receiving device includes a receiver circuit for outputting a received signal as a reception electric field intensity signal, an operation control circuit for controlling an operation of the receiver circuit, and an intermittent reception control circuit for outputting a periodic signal. A comparator circuit holds a first threshold indicating that the receiving device has entered a communication area and a second threshold indicating a start of a continuous electric field intensity measurement. If the reception electric field intensity signal is lower than the second threshold, the operation control circuit makes the receiver circuit perform intermittent operation. If the reception electric field intensity signal is equal to or higher than the second threshold, the operation control circuit makes the receiver circuit perform a continuous operation. If the reception electric field intensity signal is equal to or higher than the first threshold, the operation control circuit makes the demodulation circuit perform an operation.

摘要： A multicarrier transmitting method has the steps of: inputting n (n is an integer equal to or larger than 2) input signals; generating carriers respectively corresponding to the n input signals; modulating the carriers into n modulated signals by the input signals; generating at least one additional signal having a frequency outside a band of the n modulated signals; 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; and amplifying the multiplexed signal, and then removing the additional signal, wherein the level and phase of the additional signal are adjusted such that, after predicting in advance 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.

摘要： Disclosed is a transmitter for switching and transmitting signals of plural frequency bands. For example, the signals of two frequency bands are switched and transmitted. For the transmission in a first frequency band, both of transistors 104, 105 are turned off, whereby a power amplifying transistor 102 is matched by an input wide band matching circuit 101 and an output main matching circuit 103, so that the high efficiency linear amplification is accomplished. For the transmission in a second frequency band, the transistor 104 is turned on while the transistor 105 is turned off, whereby the power amplifying transistor 102 is matched by a capacitance 108 as well as the input wide band matching circuit 101 and the output main matching circuit 103, so that the high efficiency linear amplification is accomplished. An external switch for switching the matching circuits is thus unnecessary.

摘要： According to the configuration of the present power splitter, it is possible to reduce the characteristic impedance of a transmission line constituting a directional coupler by setting the impedance of a first terminal pair constituted of an input port 7a and a second output port 7d of a 6-dB branch-line-shaped directional coupler 7 to a value smaller than a reference impedance Z0 (50 Ω in general) and setting the impedance of a second terminal pair constituted of an isolation port 7b and a first output port 7c of the directional coupler 7 to Z0. Therefore, it is possible to increase the number of split s and reduce loss, as compared with conventional cases.
