Abstract
This application provides a radio frequency (RF) low-noise amplifier and chip. The RF low-noise amplifier includes: a first capacitor, an RF amplification module, a first bias module, a second bias module, and a reconstruction module. A first terminal of the first capacitor is electrically connected to an RF signal input terminal. A second terminal of the first capacitor is electrically connected to the output terminal of the first bias module and the first terminal of the RF amplification module. The output terminal of the second bias module is electrically connected to the second terminal of the RF amplification module. A third terminal of the RF amplification module is electrically connected to the first terminal of the reconstruction module. The second terminal of the reconstruction module is electrically connected to a power supply. This solution, by setting up a reconstruction module, allows adjustment of the RF low-noise amplifier's operating frequency band and resonant point by sending a first control signal to the reconstruction module, thereby resulting in a wider bandwidth for the RF low-noise amplifier's operating frequency band to adapt to more operating scenarios.
