摘要： An outdoor satellite receiving unit (ODU) receives several independent satellite signals, selects two signals with a switch matrix, downconverts the two signals to a bandstacked signal with a high and a low band signal, and outputs the bandstacked signal on the same cable to receiver units. Several satellite signals can be selected in groups of two or more and output to independent receiver units. Signal selecting is performed at the received radio frequency (RF) and bandstacking is performed with a single downconversion step to an intermediate frequency (IF). Channel stacking on the same cable of more than two channels from several satellites can be achieved by using frequency agile downconverters and bandpass filters prior to combining at the IF output. A slow transitioning switch minimizes signal disturbances when switching and maintains input impedance at a constant value.

摘要： A method and an apparatus from such method for designing an integrated circuit (IC) that mitigates the effects of process, voltage, and temperature dependent characteristics on the fabrication of advanced IC's but provides high die yields, lower power usage, and faster circuits. Conventional design process takes into account power supply voltage Vdd as a variable that must be considered in a skewed corner analysis. The disclosure teaches that the IC design process can be substantially simplified by essentially factoring out voltage based variations in corner lot analysis for IC designs that include dynamic voltage scaling circuitry, because each fabricated IC die of an IC design having dynamic voltage scaling can individually adjust the applied supply voltage Vdd within a range to offset local process-induced variations in the performance of that specific IC die.

摘要： A method and apparatus in which a Tap-Weight Computer (TWC) calculates a Tap-Weight Vector (TWV). The TWV is coupled to a register in each of a plurality of adaptive filter modules. Each such adaptive filter module includes several adaptive filters that each include a tapped delay line. The input to the tapped delay line of each such adaptive filter is one of a plurality of potential interfering signals. The TWV controls the weighting of the outputs from the taps off the delay line. The weighted outputs from each tapped delay line are then subtracted from a received signal which potentially includes interference from the potential interfering signals. The TWC is multiplexed to each of the plurality of adaptive filters so that each adaptive filter is loaded with a TWV calculated by the TWC to reduce the amount of interference contributed by a particular potential interfering signal coupled to an input to that particular adaptive filter. In one embodiment, a plurality of such adaptive filter modules share the same TWC.
