Abstract: Disclosed are a photonic multiband filter and a method of operating the same. The photonic multiband filter includes an optical frequency comb that forms multiple optical channels based on a single light source incident from an outside, a modulator that applies an RF signal modulated into an optical domain among a plurality of RF signals to the multiple optical channels, and a pulse shaper that determines a center frequency, a bandwidth, and a passband shape of the RF signal modulated into the optical domain including the multiple optical channels.
