ABSTRACT:
A multi-mode, multi-band mobile station for use in wireless networks operating under different air interface standards. The present invention, the mobile station comprises a plurality of low-noise amplifiers. Each of the plurality of low-noise amplifiers is optimized for use in a selected frequency band. The mobile station also comprises a near-zero intermediate frequency (NZIF) broadband image rejection mixer for receiving an amplified RF signal from a selected one of the plurality of low-noise amplifiers and down-converting the amplified RF signal to produce a first analog intermediate frequency (IF) signal.
