Band Pass Filters
These filters are developed for various type of radio equipment for business use and for base station equipment of public radio communications. There are three types available depending on operating frequency band: Herical resonator type, Coaxial resonator type and Dielectric resonator type.	Common specifications Impedance 50Ω V.S.W.R. 1.3 Max. Operating temp. -10°C to +50°C
