    摘要： The invention specifies a circuit arrangement with a radio-frequency mixer (4) in which a plurality of preamplifiers (1, 2, 3) in a receiver have a common output node (6). This node is connected to a common, broadband radio-frequency mixer (4) via common coupling capacitances (41, 42). Switching means (17, 18; 27, 28; 37, 38) can be used to connect and disconnect the preamplifiers (1 to 3), which can be associated with various frequency bands, independently of one another. The present principle can be applied in multiband receivers in mobile radio and allows integration using little chip area with good radio-frequency characteristics.

    摘要： The invention relates to a preamplifier circuit with at least one transistor that couples a signal input to a signal output. The signal input is supplied with a radio-frequency signal. In addition, the preamplifier circuit includes a switch that switchably couples the input to a reference potential and which, when the preamplifier is inactive, is closed. Hence, when the preamplifier is inactive, the input is put into a low-impedance state and the amplifier and downstream assemblies are protected from unwanted high-power interference signals. It is thus also possible to use other, fully integratable filter types in a transceiver's reception signal processing chain instead of external surface acoustic wave filters with a low level of complexity and without drawbacks.

    摘要： A fastening arrangement of a sensor element, in particular a camera, on a fastening element of a motor vehicle involves holding the sensor element on a holding element of the fastening element by means of a force generated by a spring region of a spring element and orientated in one direction. The spring element has a second spring region connected at least indirectly to the first spring region and running at angle to the first spring region, which the sensor element adjoins in a second direction that runs at an angle to the first direction.
