Fiber dispersion induced RF power fading compensated microwave photonic filter with a tunable single passband

A tunable single passband microwave photonic filter (MPF) with compensation for fiber dispersion induced radio frequency (RF) power fading is realized. When the central frequency of the MPF changes the passband amplitude can be kept invariant. The proposed MPF has a tunable range of 0–30 GHz and the rejection ratio exceeds 30 dB.
