FM Double Bridge (channels spacing > 2.5Mhz)

FM Double Bridge, Double coaxial filters Combiners

Made of aluminum, silvered copper and PTFE. They are composed of two cavity filters and 2 hybrid couplers, they have a selective input and a broadband. It is therefore necessary , in order, knowing all the frequencies of use. The cavity filters have a B.W. command that allow you to adjust selectivity and also the isolation between channels.
