Military Cavity filters in Passband 18200MHz± 500MHz
Our this series cavity filters utilize rectangular or cylindrical metal-rod resonance oscillation with coaxial cavity, interdigital, or combline coupling structures. High-quality factor (high-Q) capacitive loading is integrated to ensure superior power handling performance. The resonance cavity length is less than one-quarter wavelength along with compact size, long Parasitic pass band distance and low insertion loss. They comply with the testing procedures and environmental conditions specified in China’s GJB military standards. Ideal for 5G, satellite communications, military radar, and test equipment, our cavity filters deliver unmatched performance in critical RF applications.
