摘要： In an output-controlled power amplifier of a closed loop type, an input signal is inputted to a main path in which the input signal is power-attenuated by a variable attenuator and power-amplified by a power amplifier. A power divider distributes the amplified input signal between the main path and a feedback path diverging from the main path so that the signal distributed to the main path is outputted from the main path to the exterior while the input signal is controlled on the basis of the signal distributed to the feedback path. The feedback path includes a hold circuit for extracting the signal distributed to the feedback path and holding the value of the power of the extracted signal when the power reaches a predetermined value. A control signal for attenuating the power of the input signal inputted to the main path is generated by the hold circuit and is applied through the feedback path to the variable attenuator on the main path to control the power of the input signal. A transfer function of the closed loop has a Gaussian characteristic.

摘要： Improving the reliability of digital radio communication affected by multi-path interference under an environment where there are multiple objects that scatter electromagnetic waves is accomplished. A wireless transmitter transmits a first transmission wave having a first carrier frequency (f0+Δf), modulated by a modulator with an information signal having a frequency band f1 which is predetermined, from a transmitting antenna, and transmits a second transmission wave having a second carrier frequency (f0−Δf), modulated by a modulator with such information signal. An average frequency f0 between the first carrier frequency (f0+Δf) and the second carrier frequency (f0−Δf) is kept constant, whereas the first carrier frequency (f0+Δf) and the second carrier frequency (f0−Δf) are varied by controlling a frequency difference Δf to vary.
