Estimating the term…
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.
A tuner front end (170) for use with a tuner for tuning a channel from an RF input signal, with calibration to eliminate the need for manual adjustment of the tuner front end, comprising:
A tuner for tuning a channel constructed as a system-in-package (SIP) comprising:
A tuner with selectable front end comprising:
