A new method for remote wideband microwave frequency measurement utilizing a single-passband microwave photonic filter is proposed, theoretically analyzed, and experimentally demonstrated. The frequencies of the input microwave signals can be measured by monitoring the maximum output microwave power while scanning the central frequency of the single-passband microwave photonic filter. The parameters...
A microwave photonic filter based on a Mach-Zehnder interferometer (MZI) and a phase modulator is presented, and the experimental results show the suppressed baseband resonance and an extinction ratio of up to ~20 dB.
