ABSTRACT:
A low noise amplifier (LNA) includes an LNA input that receives a signal from an antenna. The LNA also includes an internal amplifier with an input that is coupled to the LNA input, as well as an internal filter with an input coupled to the output of the internal amplifier and an output coupled to the input of the internal amplifier. The coupling of the output of the internal filter to the input of the internal amplifier provides feedback to the input of the internal amplifier. The internal filter is configured to pass signals within a frequency range through to the output of the internal filter.
