Abstract:
A device includes at least one first amplifier circuit configurable to receive and amplify an input radio frequency (RF) signal having a first carrier at a first input signal level and provide a first amplified RF signal, and at least one second amplifier circuit configurable to receive and amplify the input RF signal having a second carrier at a second input signal level and provide a second amplified RF signal, the at least one first amplifier circuit having a first input impedance, the at least one second amplifier circuit having a second input impedance.
