RF filters play an important role in the production of wireless communication products and systems, and the fabrication and application of various waveform components. They are the basis for reliable and stable communication systems. FI168L2200G9-T is one of them. It is mainly used in wireless communication applications, such as 5G base station, game battlefield, UAV espionage flight system, satellite communication system, aircraft, ship and so on. 
What is FI168L2200G9-T
FI168L2200G9-T is a media filter of wave interpolation. It realizes the function of wave interpolation through the combination of the coupling of transmission lines and the resonance of capacitance and inductance. It is composed of inductors and capacitors to form an intermediate frequency filter. It has high stop band, small insertion loss, good frequency selection and good temperature stability. Its pass band frequency range is from 200 to 2200MHz. 
FI168L2200G9-T Application Fields
FI168L2200G9-T is a wide pass band medium filter with high performance, which is widely used in 5G base station equipment and new generation MIMO systems. In addition, it can also be used in radio remote control systems, game battlefield systems, UAV espionage flight systems, satellite communication systems, aircraft systems, and ship systems. It is suitable for applications where a high performance filter with an excellent heat and vibration resistance is required.
FI168L2200G9-T Working Principle
The FI168L2200G9-T consists of two parts, namely the coupled line and the resonance circuit. The coupled line makes up the pass band and the resonance circuit makes up the stop band of the filter. The coupling of transmission lines produces microstrip sections with different impedances, which produce pass bands and stop bands in the pass band frequency range. The resonance circuit provides additional stop bands.  The resonance circuit is composed of inductance and capacitance and can produce resonant frequencies in the stop band range. The two parts form a high-performance RF filter and can achieve desired filter characteristics with minimal insertion loss.
Conclusion
FI168L2200G9-T is a high-performance wave interpolation filter with a wide pass band and excellent temperature stability. It is mainly used in wireless communication applications such as 5G base stations, game battlefields, UAV espionage flights, satellite communication systems, aircraft, and ships. It consists of coupled lines and resonant circuits, which provides pass band and stop band respectively. Therefore, it is suitable for any application that requires a filter with high performance and excellent heat resistance.
