  • Load variation tolerant radio frequency (RF) amplifier
    Patent number: 6954623
    Abstract: A power amplifier having a phase shift and impedance transformation element is disclosed. The power amplifier comprises a plurality of amplification paths, a first phase shift element at an input of each amplification path and a second phase shift element at an output of each amplification path. The amplifier also comprises an impedance transformation element associated with the second phase shift element and a power combiner configured to combine an output of each amplification path into a single output.
    Type: Grant
