Summary:The present disclosure relates to variable-gain low noise amplifiers and RF receivers. An exemplary method for processing a RF signal provides a low noise amplifier with main and auxiliary amplifier modules. When a selection indicates the low noise amplifier operating in a high-gain mode, the main and auxiliary amplifier modules are coupled in parallel. When the selection indicates the low noise amplifier operating in a low-gain mode, the main and auxiliary amplifier modules are cross coupled. When a selection indicates the low noise amplifier operating in a moderate-gain mode, the auxiliary amplifier modules are disconnected from the main amplifier module.
