Description
Summary:This letter describes a single RF channel using a fully integrated multiplex LNA (Low Noise Amplifier) with four input channels and a double-balanced mixer in a 0.35 mum CMOS technology for SMILE (Spatial MultIplexing of Local Elements) applications. This technique is a front-end architecture which uses only one RF channel, carrying multiplexed information from multiple antennas. The performance characteristics of this single RF channel like gain, isolation, noise figure, IIP3, and matching are shown in this work. The specifications and performance are in close agreement, validating the proposed compact design.
