  • Patent number: 9118403
    Abstract: A compact automatic gain control module for an RF amplifier includes a microchip Tuner for detection of pilot signals in an incoming RF signal. By selectively tuning into pilot signals in response to command from an on-board microprocessor, the module is frequency agile in the selection of pilot signals, selecting specifically advantageous signals for use as a pilot. Use of a microprocessor also enables specific advantages in receiving firmware upgrades to incorporate algorithms for operation parameter monitoring and adjustment of response in accord with monitored parameters. Such monitoring also enables the recording of on-module events that enable storage of a log to enable maintenance and performance enhancement within the module.

  • Patent number: 8174441
    Abstract: A configurable calculating circuit includes a multiplexer, a mixer and an accumulator. The multiplexer is for receiving input signals including at least a first and a second input signals, and selectively outputting at least one of the input signals. The mixer is for mixing a selected input signal outputted from the multiplexer with a local oscillation signal to generate a mixed signal. The accumulator is for accumulating the mixed signal to generate an accumulated signal. When the configurable calculating circuit is operated under a first mode, the multiplexer selects the first input signal, and the accumulator performs a first accumulating operation upon the mixed signal; and when the configurable calculating circuit is operated under a second mode, the multiplexer selects the second input signal, and the accumulator performs a second accumulating operation, different from the first accumulating operation, upon the mixed signal.
