Abstract

In accordance with an embodiment, a radio-frequency (RF) front-end for a radio configured to receive an RF signal at a first frequency includes an antenna port configured to be coupled to an antenna, and a notch filter having an input coupled to the antenna port. The notch filter is configured to reject one or more frequencies, such that the first frequency is a harmonic or intermodulation distortion product of the one or more frequencies. The RF front-end also includes a piezoelectric filter having an input coupled to an output of the notch filter and an output configured to be coupled to an RF amplifier. The piezoelectric filter has a pass band comprising the first frequency.
