Abstract

An amplifier includes first, second, and third inputs to receive an RF signal, first and second amplifiers, and an input phase adjustment circuit coupling the first, second, and third inputs to the first and second amplifiers, the input phase adjustment circuit having first and second outputs coupled to the first and second amplifiers, respectively. The input phase adjustment circuit includes a pair of inputs, where the pair of inputs includes the first and second inputs, for the first output and a pair of phase adjustment paths coupling the pair of inputs to the first output, respectively. The pair of phase adjustment paths are configured to adjust a phase of the RF signal differently for the first output.
