Abstract: Systems and apparatuses are provided for negating the degradation effects of fundamental coupling between at least two near field communication (NFC) enabled devices, at least one of which can receive frequency modulation (FM) signals. Due to the fundamental coupling, strong NFC signals can mix with blocking signals associated with a desired/tuned-to FM frequency causing degradation in FM receiver performance. By utilizing a notch filter at the front end of the FM receiver, the degradation in FM receiver performance caused by the fundamental coupling phenomenon can be avoided.

Abstract: An FM transmitter operates at low power by maintaining a substantially constant transmit voltage over the FM frequency band. A transmit signal strength indicator (TSSI) is provided at the output of the FM transmitter to measure the power at the output of the power amplifier. The TSSI generates a power control signal indicative of the output power and inputs the power control signal to the baseband processor. The baseband processor generates gain control signals to control the gain of various analog stages of the FM transmitter based on the power control signal.
