To provide techniques for operating a receiver to achieve good linearity performance and higher receive signal to noise ratio.
The receiver includes one or more circuit blocks, e.g., a low noise amplifier (LNA), having discrete gain states. The gain states are selected based on switch points, with each switch point indicating a specific received signal level for switching from one gain state to another gain state. The switch points may be dynamically selected based on channel conditions, which may be characterized by the presence or absence or intensity or frequency of radio interference. A first set of switch points may be selected when radio interference is detected, and a second set of switch points may be selected when radio interference is not detected. The gain states are selected in accordance with the set of switch points selected for use.
