Abstract

This application relates to the field of power amplifier circuit structure technology, and discloses a Kicker-based power amplifier circuit structure, including a signal source, an amplifier, a coaxial 1-to-2 splitter, a Kicker load, and a 50Ω resistor. The signal source is used to provide the original signal. This Kicker-based power amplifier circuit structure, by setting a coaxial 1-to-2 splitter, a 50Ω resistor, and a Kicker load, uses a coaxial 1-to-2 splitter to replace the traditional rheostat, eliminating the need for a complex impedance matching network (such as a 1:9 rheostat), reducing the number of components by more than 50% (quantifiable in specific embodiments). The output terminal of the coaxial 1-to-2 splitter is connected to the Kicker load via a coaxial cable, avoiding the complex wiring in traditional circuits. The 50Ω resistor is connected in parallel at the amplifier output terminal. Through equivalent impedance matching, the power amplifier output power requirement is reduced by 30%-40%, and the overall system energy consumption is reduced by more than 25%. The power capacity of the 50Ω resistor is not less than the maximum output power of the amplifier, ensuring matching stability.
