Patent ID: 8260215

Claim:
A communications device, comprising: a first radio frequency (RF) element coupled to an antenna and comprising a low side injection path for transforming an input RF signal received by said communications device into a first conditioned RF input signal limited to a first frequency range and a high side injection path for transforming said input RF to a second conditioned RF input signal limited to a second frequency range higher than said first frequency range; at least one injection switch for selecting one of said first and said second conditioned RF input signals; a first local oscillator (LO) circuit for generating at least a first LO signal, said first LO circuit having an operating frequency range spanning at least a portion of a first inclusive frequency range defined by a lowest frequency of said first frequency range and a highest frequency of said second frequency range; a first mixer coupled to said at least one injection switch for generating a first intermediate frequency (IF) signal based on a selected one of said first and said second conditioned RF input signals communicated to said first mixer by said injection switch, and exclusively said first LO signal; and a first IF element for conditioning said first IF signal.
