Abstract
A power splitter for use in an amplifier (e.g., a Doherty amplifier) includes an input terminal, and first and second output terminals. The input terminal is configured to receive an input RF signal, the first output terminal is configured to produce a first RF output signal, and the second output terminal is configured to produce a second RF output signal. The power splitter also includes a first capacitance electrically coupled between the input terminal and the first output terminal, a second capacitance electrically coupled between the input terminal and the second output terminal, a first inductance electrically coupled between the input terminal and a ground reference node, a second inductance electrically coupled between the first output terminal and the ground reference node, a third inductance electrically coupled between the second output terminal and the ground reference node, and a resistance electrically coupled between the first and second output terminals.
