Model No: 8CF-8-500
UBS offers a line of compact low-loss bandpass filters for analogue and DTV system applications. The filter is designed in comb-line filter technology for small size, and consists of 8 screened resonators for the effective spurious suppression. The inductive couplings between the resonators permit low operating voltage within the filter. The resonators are silver-plated for low insertion loss. The filters are constructed from lightweight aluminum that provides solid mechanical and temperature stability, and come complete with the necessary hardware and test data.
Features
· 500W maximum input power
· Chebyshev response
· DTV Non-Critical Mask Applications
· 19'' rack Mountable
· Very compact and lightweight
