摘要： A feedforward amplifier includes a power divider for dividing the input signal into first and second signals. The first signal is processed in a first path that includes, in sequence, a first vector adjuster, a main amplifier, a directional coupler and a delay circuit. The second signal is delayed in a second path that includes, in sequence, another delay circuit, a first power combiner and an auxiliary amplifier block. The first power combiner combines the first signal, by way of a coupling port from the directional coupler, with the second signal to provide a combined signal into the auxiliary amplifier block. The auxiliary amplifier block further divides the second signal into two divided signals, each having a respective non-overlapping frequency band. The two divided signals are respectively vector adjusted, amplified, and then recombined. The recombined signal is then recombined with the processed signal in the first path to provide the desired output signal.

摘要： In the receiver using a PLL synthesizer, there is a limit in reducing boot-up time or frequency switching time, which shortens battery life. A first local frequency L01 from a multiplier 22 and a receiving signal are input to a first frequency converter 10 to convert it to a first intermediate frequency IF1. The first intermediate frequency IF1 is converted in a second frequency converter 12 by a frequency L02 of an N1 frequency divider 24 to a second intermediate frequency IF2. Also, the outputs of the N1 frequency divider 24 and N2 frequency divider 26 are mixed in the frequency converter for transmission 34, and L04 and the local frequency L01 are added to a lower-side-band cancel mixer 50 to extract the upper side band of the transmission frequency. With the configuration in which a frequency may be varied by one channel interval by varying the frequency division number of the N1 frequency divider 24 by one, switching of frequency division number permits channel switching for both transmission and reception.

摘要： A method and apparatus for controlling a feedforward amplifier, wherein a superior distortion compensation characteristic is maintained over a wide frequency range, with the influence due to temperature variation and weathering minimized. A pilot signal generated by a pilot signal generator circuit is injected into the output of the main amplifier of a feedforward amplifier, and then the signal is sampled at the output of a first circuit and a second circuit, which is then low-range converted by a frequency converter and demodulated into I and Q components by a quadrature demodulator, and amplified and shaped into a pilot monitor signal; and a control circuit controls the vector adjusters within the distortion suppression circuit of the first and the second circuits using the I and Q signal components as the error signal so that as the amplitude level of pilot monitor signal is mininized the control value is maintained.

摘要： A fraction part control circuit of a frequency synthesizer apparatus including a PLL circuit is of a plural-n-th-order delta-sigma modulator circuit for controlling a fraction part of a number of frequency division to a variable frequency divider of the PLL circuit. An adder adds data of the fraction part to an output data from a multiplier and outputs the resultant data to a quantizer through a second-order integrator. The quantizer quantizes input data with a quantization step and outputs the quantized data to the multiplier through a feedback circuit. The quantized data is used as data of the controlled fraction part. The multiplier multiplies data from the feedback circuit by the quantization step and outputs the resultant data to the adder. The fraction part control circuit periodically changes the data of the fraction part, thereby setting a frequency of an output signal from a VCO according to an average value of the period.
