Patent abstract
A transmission line transformer is disclosed. The transformer improves efficiency and a dynamic range of a power amplifier. The transformer is formed to have a plurality of load impedances as the primary side of the transmission line transformer is separated to form a plurality of primary transmission lines with parasitic components which are different from each other. The transformer is used as an impedance matching circuit of the power amplifier requiring a plurality of load impedances.
