Document Type and Number:
WIPO Patent Application WO/2023/019911
Kind Code:
A1
Abstract:
The present application provides a radio frequency amplifier and a 1dB compression point dynamic adjustment circuit thereof. The 1dB compression point dynamic adjustment circuit of the radio frequency amplifier is connected to an output stage of the amplifier. The output stage of the radio frequency amplifier comprises a first three-terminal transistor and a second three-terminal transistor connected in series. The adjustment circuit comprises: an input signal detector which is connected to a control terminal of the first three-terminal transistor and detects an amplitude of an input signal acting on a control terminal of the first three-terminal transistor. A bias voltage generation circuit is connected to the input signal detector, is connected to a control terminal of a second triode, and generates a bias voltage of the second three-terminal transistor according to the amplitude of the input signal.
