The invention relates to a method for detecting and processing the amplitude and phase of signal waves. A Modulated signal source generates the signal waves which are modified by transmission medium or by reflection and scattering by at least one object. The modified signal waves are received and demodulated using a modulation signal. The amplitude of the modulated signal waves and their phase relationship to the modulation signal are measured and evaluated. The demodulated signal wave is converted into an electrical charge or charge displacement in the receiving medium and is distributed in accordance with a modulation signal to at least two readout outputs and fed to an evaluation unit. The evaluation unit produces the sum and difference of the output signals thus applying the value of the intensity and the phase position of the signal wave that has been scattered, reflected or delayed by the object.

A low-noise amplifier in a receiver has a differential mode of operation and at least one single-ended mode of operation. A control signal is used to select between or among the modes and the switching between differential and single-ended operations may be performed on the fly.

To provide a microwave / milliwave UWB pulse wireless communication device that enables realization of structural simplification, high performance, compact integration, easy design, low power consumption, and low cost. A radiation type oscillator is configured by a radiation type oscillator substrate S1 equipped with a microwave transistor 1 for generating negative resistance by short-duration operation and a resonant cavity structure, a high-frequency pulse signal of an oscillation frequency / frequency bandwidth determined based on negative resistance produced by the short-duration operation of the microwave transistor 1 and the resonant cavity structure is generated as a transmitted RF signal and simultaneously radiated into space, and the radiation type oscillator is caused to perform oscillating operation when a received RF signal arriving from an external wireless communication device enters the radiation type oscillator, whereby a received data signal is established based on acquisition of an IF signal owing to mixing by the radiation type oscillator itself.

The invention relates to a method for detecting and / or processing signal waves that produce charge carriers in an article sensitive to the signal waves, said charge carriers inducing a signal current in at least one readout electrode. At least two modulation electrodes are provided, at least one of which is disposed in the proximity of the at least one readout electrode or to another readout electrode in such a manner that, depending on the polarity sign of the modulation volatage of the respective modulation electrode, the current flowing across the associated readout electrode is positive or negative. The invention further relates to a device for detecting and processing signal waves. Said device comprises an OEP article that is sensitive to the signal waves, in which article the signal waves produce charge carriers, and at least one readout electrode (AK) that is linked with the charge carrier range of the article. At least two modulation electrodes (MKa, MKb) are provided, at least one of which is disposed in the proximity of the at least one readout electrode (AK) and the other in the proximity either of the same readout electrode (AK) or of another readout electrode (AK2). The aim of the invention is to provide a method and a device that is capable of interlinking various optical and / or electronic signals in a logically digital or analogous manner or to detect the course of optical signals by scanning (time interval measurements). For this purpose, the modulation electrodes are modulated with relatively freely selectable voltage amplitude and / or phase relation, whereby the readout currents produced by the modulation voltages of the two modulation electrode are additively coupled. The inventive device is characterized in that the modulation electrodes are disposed relative to the readout electrode(s) in such a manner that, depending on the polarity sign of the modulation voltages of the respective modulation electrode, the current flowing across the associated readout electrode is positive or negative and that at least one device is provided by which the relative phase relation and / or the voltage amplitude of the two modulation voltages can be freely adjusted.
