POWER AMPLIFICATION CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18446542 titled 'POWER AMPLIFICATION CIRCUIT

Simplified Explanation

The patent application describes a power amplification circuit that adjusts the amplification based on the input signal.

• The circuit includes a splitter with variable inductance and capacitance elements to divide the signal into two power levels.
• A carrier amplifier amplifies the signal, while a peaking amplifier only outputs a signal if the second power level meets a certain threshold.
• The two signals from the amplifiers are then combined using a combiner.

Original Abstract Submitted

A power amplification circuit performs power amplification appropriate for the condition of an input signal. The power amplification circuit includes a splitter that includes a variable inductance element and a variable capacitance element and that splits a signal into a signal having a first power level and a signal having a second power level based on a value of inductance of the variable inductance element and a value of capacitance of the variable capacitance element. A carrier amplifier is connected to the splitter and amplifies the signal and output a signal. A peaking amplifier is connected to the splitter and outputs a signal when the second power level is greater than or equal to a predetermined power level, and a combiner (combines the two signals from the respective amplifiers.
