Abstract
Embodiments of a radio frequency (RF) receiver implementing one or more forms of protection to protect devices of the RF receiver from in-band interferers is provided. The RF receiver includes an integrated circuit terminal configured to couple a RF signal received at an antenna to a RF signal path, and a low noise amplifier (LNA) coupled to the RF signal path and configured to amplify the RF signal to provide an amplified RF signal. To protect the LNA from in-band interferers, the RF receiver can further include one or more clamping circuits and/or an over-voltage detector to determine if a peak of the RF signal exceeds an acceptable level.
