Abstract
A satellite receiver having first and second stages that are serially coupled so that an output of the first stage feeds into an input of the second stage is provided. Each of the first and second stages includes a tunable oscillator for providing a reference frequency, a means coupled to the input and the tunable oscillator for mixing a frequency modulated (FM) signal on that stage's input with the reference frequency to provide an intermediate frequency (IF) FM signal, and a bandpass filter for filtering the IF FM signal and providing the filtered IF FM signal to that stage's output.
