POWER AMPLIFIER CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18403741 titled 'POWER AMPLIFIER CIRCUIT
The patent application describes a power amplifier circuit consisting of three amplifiers and a harmonic suppression circuit. The first amplifier amplifies a signal in a specific frequency band, the second amplifier amplifies a signal in a different frequency band, and the third amplifier amplifies a receive signal in the second frequency band.
- The first amplifier operates on power from a first supply line.
- The second amplifier operates on power from a second supply line connected to the first supply line.
- The third amplifier shares an antenna with the second amplifier to amplify the receive signal.
- The harmonic suppression circuit generates a suppression signal based on a harmonic of the first transmit signal to prevent the transfer of unwanted harmonics to the power supply lines.
Potential Applications: - Wireless communication systems - Radio frequency transmitters - Signal amplification in electronic devices
Problems Solved: - Minimizing harmonic interference in power amplifiers - Enhancing signal quality in different frequency bands

Original Abstract Submitted
A power amplifier circuit includes a first amplifier, a second amplifier, a third amplifier, and a harmonic suppression circuit. The first amplifier operates on power supplied through a first supply line, and amplifies a first transmit signal in a first frequency band. The second amplifier operates on power supplied through a second supply line connected to the first supply line, and amplifies a second transmit signal in a second frequency band different from the first frequency band. The third amplifier shares an antenna with the second amplifier, and amplifies a receive signal in the second frequency band received from the antenna. The harmonic suppression circuit generates, based on a harmonic of the first transmit signal, a suppression signal to suppress the harmonic to be transferred to the first supply line, and outputs the suppression signal to the first supply line or the second supply line.
