| description | A radio frequency low-noise amplifier circuit and a radio frequency chip includes a signal input end, an input matching circuit, an amplification circuit, an output matching circuit, a signal output end, and a gain adjustment circuit connected in parallel with the amplification circuit. The gain adjustment circuit includes a tenth transistor, an eleventh transistor, a twelfth transistor, a first resistor, a second resistor, a third resistor, and a fourth capacitor. A source of the tenth transistor, a source of the eleventh transistor, and a source of the twelfth transistor are connected and are grounded. The tenth transistor is connected to the first resistor, the eleventh transistor is connected to the second resistor, and the twelfth transistor is connected to the third resistor. The first resistor, the second resistor, and the third resistor are connected to the fourth capacitor. The fourth capacitor is connected to the amplification circuit. |
