ABSTRACT:
A gain-controlled RF amplifier system has an input node and an output node. The system has a plurality of amplifier devices, selectively connectable between the input node and the output node. The amplifier devices are placed in circuit according to a measured gain derived by comparing a magnitude of a signal input to the input node against a magnitude of a signal output from the output node, and a desired value of gain.
