Application: Radio frequency circuit, communication device, and antenna module (Patent ID: US20240146248A1)
The patent filed by Murata Manufacturing Co Ltd describes a radio frequency circuit that includes a power amplifier capable of selectively amplifying radio frequency signals with different bandwidths. The circuit applies different bias signals to the power amplifier depending on whether a first or second radio frequency signal is being input. The bias voltage of the signal tracks changes in power amplitude of the amplified signal, with the degree of tracking corresponding to the bandwidth of the radio frequency signal being amplified.
Furthermore, the circuit includes features such as a bias power supply circuit to output the bias signal, different bias power supply circuits for adjusting bias signals at varying degrees, and a filter connected to the amplifier's output terminal to accommodate different frequency ranges. The patent also extends to communication devices incorporating the radio frequency circuit and antenna modules utilizing the circuit to radiate amplified radio frequency signals. Overall, the invention aims to optimize the performance of the power amplifier based on the characteristics of the input radio frequency signals, ensuring efficient amplification tailored to different modulation schemes and communication systems.
