Providing Multiple Inductors For A Radio Tuner

摘要

A method includes receiving a desired channel indication in a radio tuner, determining a band of operation in which the channel is located, and if the channel is within a first band coupling multiple inductors into a resonant tank, and if the desired channel is within a second band coupling a single inductor into the resonant tank.

主权项

1. An apparatus comprising:
a receiver formed on a single semiconductor die adapted in an integrated circuit (IC), the receiver having a single radio frequency (RF) front end including a low noise amplifier (LNA) coupled to a first pin of the IC to receive and process RF signals of a first frequency band and a second frequency band via a single signal path, the single RF front end including a varactor to provide a selected capacitance level to resonate with an inductance coupled to the IC, the receiver further including a controller to cause a capacitor to be coupled with the inductance if the RF signal is of the first frequency band.
