    Abstract: A broadband tuner includes a tracking filter with calibration to compensate for component errors and drift. The filters use off-die inductors that are preferably within a system-in-package (SIP) with other critical tuner components, which produces a highly integrated tuner front end with high Q filters within a single package. High voltage varactors with a large tuning range can be used for variable capacitors. The integration of the tuner into a SIP allows the tuner design to be optimized for cost and performance while keeping the critical RF layout requirements within the tuner. A configurable tuner front end enables modes for low noise, high linearity, good input return loss (S11) across the entire RF band, and applying a test tone in the calibration mode. The switchable mode enables the tuner to be effective during weak terrestrial reception, strong terrestrial reception, and connection to a cable plant.

    Abstract: A cascadable AGC amplifier in a signal distribution system includes a low noise cascadable amplifier having a through path and a cascadable output. The cascadable amplifier is also configured to provide AGC over a predetermined input power range. The cascadable AGC amplifier can be configured to provide gain or attenuation. When the cascadable AGC amplifier is implemented in a signal distribution system, typically as part of a signal distribution device, an input signal can be gain controlled and supplied to multiple signal paths without distortion due to degradation of signal to noise ratio or distortion due to higher order amplifier products. The distributed signal is not significantly degraded by distortion regardless of the number of cascadable AGC amplifiers connected in series or the position of the cascadable AGC amplifier in the signal distribution system.
