Abstract
A radio frequency (RF) receiver that includes a low noise amplifier (LNA), a tunable resonant circuit, and a processor for performing calibration of the RF receiver. The processor is configured to sweep the tunable resonant circuit through a dynamic range of resonant frequency settings while estimating noise signal output power at the LNA at each setting. The processor is also configured to set the tunable resonant circuit to the setting that produces the greatest noise signal power output at the LNA.
