摘要： A radio system includes a radio frequency (RF) integrated circuit (IC) and a baseband digital signal processing (DSP) IC. A serial digital interface couples data between the RF IC and the DSP IC to provide a high data rate and low noise. In one embodiment, the RF IC has a single bit sigma delta modulator to convert an analog signal into a serial digital bit stream, and a differential output driver to drive the serial digital bit stream as a differential data signal. In one embodiment, the DSP IC has a differential input receiver to receive the differential data signal and generate the serial digital bit stream therein, a decimator to lower the data rate of the serial digital bit stream and convert it into parallel digital data samples, and a demodulator to digitally demodulate the parallel digital data samples into data words for digital signal processing.

摘要： A system, apparatus and method for providing filtering functionality and impedance transformation within a BAW resonator network are disclosed. In particular, a BAW resonator network is designed to provide bandpass capability and a transformation between its input impedance and output impedance. By effectively integrating impedance matching functionality within the BAW resonator network, discrete impedance matching elements previously required within a system may be removed or reduced in size. As a result, matching networks and their associated component costs, insertion losses, and board size contributions may be reduced. Harmonic termination may be provided within the BAW resonator network or a prematch stage to improve efficiency of a power amplifier.

摘要： The invention relates to a drive for adjusting motor vehicle seats comprising a spindle (5) fixed to a first (4) of two rails (3, 4) which are adjustable with respect to each other with the aid of holding devices (60) arranged on the end of the spindle (5). A transmission (9) actuated by a motor (2) is placed on the second rail (3), According to id invention, the holding devices (60) comprise an external bowl-shaped supporting surface (66) in which each end of the spindle (5) is fixedly mounted, respectively. Said solution is more advantageous in comparison with conventional holding devices which are embodied in the form of flexible stamped parts, in particular the inventive holding devices exhibit a high resistance in the case of crash.
