Abstract
Apparatuses and methods for implementing a photonic radio front end are provided. An example apparatus may include a photonic comb filter configured to generate a photonic pulse train at a plurality of carrier frequencies, and a photonic upconverter. The photonic upconverter may be configured to receive outbound data from a data source, and encode and photomix the outbound data onto each of the carrier frequencies within the plurality of carrier frequencies to generate associated upconverted waveforms on each of the carrier frequencies. The apparatus may further comprise a transmit channel selector configured to receive the upconverted waveforms on each of the carrier frequencies, receive a control signal selecting one or more carrier frequencies for transmission of the outbound data, and filter out the upconverted waveforms at unselected carrier frequencies to provide upconverted waveforms at the selected carrier frequencies.
