Abstract
Official abstract text for this publication.
Various embodiments implement apparatuses and methods for conversion of radio frequency (RF) signals to intermediate frequency (IF) signals. More particularly, some embodiments are directed toward down conversion of RF signals to IF signals in a multi-band radio receiver, such as a satellite receiver, using a single oscillator for different frequency bands. For example, some of the apparatuses and methods presented are suitable for integration into monolithic RF integrated circuits in low-cost satellite receivers for home entertainment use.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for conversion of radio frequency (RF) signals in a plurality of frequency bands to intermediate frequency (IF) signals, comprising: an oscillator capable of generating an oscillator frequency LO; a first down conversion chain configured to down convert signals in a first received radio frequency band RF 1 , comprising: a first first-stage mixer coupled to the oscillator and configured to down convert RF 1 using the oscillator frequenc…
