CURRENT-EFFICIENT LOW NOISE AMPLIFIER (LNA)

摘要

A device includes a multi-mode low noise amplifier (LNA) having a first amplifier stage, and a second amplifier stage coupled to the first amplifier stage, the second amplifier stage having a plurality of amplification paths configured to amplify a plurality of carrier frequencies, the first amplifier stage configured to bypass the second amplifier stage when the first amplifier stage is configured to amplify a single carrier frequency.
