ABSTRACT:
An amplifier includes: an input stage for receiving an input signal to generate a first signal corresponding to a first band; a first modulator coupled to the input stage for modulating the first signal to generate a second signal corresponding to a second band; an amplifier stage coupled to the first modulator for processing the second signal to generate a third signal, wherein the third signal includes a fourth signal corresponding to the second band and a first interference signal corresponding to the first band; and a second modulator coupled to the amplifier stage for modulating the third signal to generate a fifth signal corresponding to the first band and to generate a second interference signal corresponding to the second band.
