摘要： A directional coupler that can be produced entirely in integrated technology (MIC or MMIC), particularly for the X-band. The directional coupler can be designed for a high coupling attenuation (>30 dB) and a high directivity (>30 dB) with a large relative bandwidth (approximately 20%). This is achieved with a stepped arrangement comprising a plurality of .lambda./4 waveguide sections and coupling capacitors disposed between the respective paths of the coupler.

摘要： A lock-in amplifier with an additional phase-sensitive detector is provided. A measurement signal is mixed in a multiplicative fashion with a reference signal, which is phase-shifted by 90 degrees, for a modulation frequency. In order to reliably filter out interference signal portions in a widest possible dynamic range and, at the same time, minimize unavoidable influence on the useful signal portion, a control device is connected downstream of the additional phase-sensitive detector. The control device determines a control variable corresponding to the strength of the interference signal from the measurement signal mixed with the reference signal phase shifted by 90 degrees and uses the control variable to change the integration duration of the integrator proportionally to the control variable, a corresponding cut-off frequency of an equivalent low pass being coordinated automatically.

摘要： The invention relates to a NDIR two beam gas analyser in which infrared radiation is guided by modulation in an alternating manner through a measuring chamber and a reference chamber and is subsequently detected, a measurement signal being produced due to the analysis which determines the concentration of a measurement gas component present in the measurement chamber. The detection and compensation of error effects, in particular modifications on the infrared radiation source or detector arrangement, is simplified as a phase imbalance is produced in the switching of the radiation between the chambers, and the measurement signal is detected in a phase-sensitive manner for modulating the radiation, a measurement signal vector (SF) comprising amplitude information and phase information (ΦF) is obtained such that during calibration of the gas analyser for different known concentrations (K1, K2, K3, K4, K5) of the measurement gas components, measurement signal vectors (S1, S2, S3, S4, S5) having different amplitudes and phases are determined, vectors define a characteristic line (43), and when an unknown concentration of the gas component is measured, the unknown concentration of the measurement gas component is determined from the intersection point (45) of an obtained measurement signal vector (SF) or the extension thereof with the characteristic line (43).

摘要： The invention relates to a NDIR-gas analyser comprising an infrared radiation source (1), a measuring vessel (3) containing a gas mixture (4) having a measuring gas component (5) that is to be detected, and a detector device (7) that is arranged behind the measuring vessel that can detect the influence of ageing of the radiation source (1) and optionally dirt deposits in the optical radiation path without interrupting measuring. According to the invention, at least one optopneumatic detector (15) is arranged in the beam path of the radiation source (1), said detector being filled with any gas (16) when arranged between the radiation source (1) and the measuring vessel (3). The concentration of measuring gas components is lower in the detector (15) than in the measuring vessel (3) if filled with the measuring gas components, and said detector is filled with a gas when arranged between the measuring vessel (3) and the detector device (7), the absorption spectrum of the detector being outside of the spectrum of the measuring gas components (5) and other transversal gases in the gas mixture (4). The measuring signal (12) of the detector device (7) is corrected by the detector signal (21) generated by the detector (15).

摘要： A controlled, saturated high frequency power amplifier, which can be used especially as a transmitting amplifier in a T/R module for a phase-controlled (radar) antenna for the X-band (8 GHz to 12 GHz). In this case, a portion of the HF output signal is utilized to generate a control signal, with which the output power is controlled nearly without loss via at least one gate connection for the HF power amplifier components, preferably, field effect transistors, that are components of the power amplifier. The power amplifier thus has a high degree of transmitting effectiveness, even with a pulsed transmitting operation.
