Patent ID: 8570103

Claim:
A power amplification (PA) module having an interchangeable-output function, comprising: a pre-processing unit having a first input, a second input, a first output containing information from said first and second inputs and a second output containing information from said first and second inputs; a phase-and-amplitude compensation circuit downstream of said pre-processing unit; a first power amplification unit downstream of said phase-and-amplitude compensation circuit; a second power amplification unit downstream of said phase-and-amplitude compensation circuit, wherein said first and second power amplification units are arranged in parallel; a post-processing unit downstream of said first and second power amplification units, wherein said post-processing unit has a third input, a fourth input, a third output containing information from said third and fourth inputs and a fourth output containing information from said third and fourth inputs, wherein said third output is associated with an amplification of said first input, wherein said fourth output is associated with an amplification of said second input, wherein said post-processing unit comprises a first output port for said third output interchangeable with said fourth output and a second output port for said fourth output interchangeable with said third output; and an optimizer in a signal path between said phase-and-amplitude compensation circuit and said post-processing unit, wherein said optimizer is configured to generate a parameter for said phase-and-amplitude compensation circuit.
