Abstract
This application provides example variable gain amplifiers and example phased array transceivers. One example variable gain amplifier includes an amplification circuit, configured to amplify an input signal; a control circuit, configured to control a gain of the amplification circuit by adjusting an output current of the amplification circuit; an inductive load, where the inductive load is coupled to a signal output end of the amplification circuit; and an inductive adjustment circuit, where the inductive adjustment circuit and the inductive load are inductively coupled, and where the inductive adjustment circuit is adjustable.
