Efficient receiver frequency plan for covering multiple frequency bands

摘要

A communications system includes a radio frequency (RF) element (104) for transforming an input RF signal into at least one of a first conditioned RF input signal associated with a first frequency range and a second conditioned RF input signal associated with a second frequency range higher than the first frequency range. The system also includes a local oscillator (LO) circuit (106) for generating at least a first LO signal, the LO circuit having an operating frequency range spanning at least a portion of a first inclusive frequency range defined by a lowest frequency of the first frequency range and a highest frequency of the second frequency range. The system further includes a mixer (108) for generating a first intermediate frequency (IF) signal based on one of the first and the second RF input signals and the first LO signal, and an IF element (110) for conditioning the first IF signal.
