    摘要： A wafer probe station is provided with a wafer chuck, a wafer fastened on the chuck by vacuum suction, and a probe needle arrangement above the wafer to test the wafer at high frequencies by contacting selected pads on the wafer and alternately pads on a calibration substrate also fastened on the wafer chuck. A procedure for reproduction of a calibration position of an aligned and afterwards displaced calibration substrate uses first and second measurement systems to calculate a new offset position of the calibration substrate after a second wafer is loaded on the wafer chuck. In a last step, the wafer chuck is driven by a 4axis manipulator stage to the new calibration position from the recent position.

    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.
