PURPOSE: A microwave photonic variable filter system and a method thereof which uses wavelength fixing light source is provided to reduce a processing time by using a wavelength fixing light source. CONSTITUTION: An optical amplifying unit(600) amplifies an optical modulation RF(Radio Frequency) signal combined with an optical coupling unit. A microwave photonic filter(11) performs RF signal process of the optical modulation RF signal. An optical detecting unit(1000) detects the optical modulation RF signal. The optical detecting unit converts the detected optical modulation RF signal into an RF signal. An RF signal processing unit(1100) outputs the converted RF signal. |
