Patent ID: 8903343

Claim:
An apparatus comprising: a first amplifier circuit configured to receive an input radio frequency (RF) signal and to amplify the input RF signal based on a first variable gain to provide a first amplified RF signal, the input RF signal comprising a plurality of signals received by a wireless device; a second amplifier circuit configured to receive the input RF signal and to amplify the input RF signal based on a second variable gain to provide a second amplified RF signal; and a third amplifier circuit configured to receive the input RF signal and to amplify the input RF signal based on the first variable gain to provide a third amplified RF signal, wherein the first amplifier circuit, the second amplifier circuit, and the third amplifier circuit are included in a low noise amplifier (LNA) configured to receive the input RF signal, to output a first amplified output signal based on the first amplified RF signal during a first operating mode and during a second operating mode, to output a second amplified output signal based on the second amplified RF signal during the first operating mode, and to output the second amplified output signal based on the third amplified RF signal during the second operating mode.
