Jampro Antennas introduced the new Jampro UHF RWED-516-U compact TV mask/filter combiner at NAB2008.
The mask/filter incorporates four-port directional filter/combining that can be used either as a mask filter or as a constant impedance-combining module for high-power UHF TV broadcasts.
The RWED-516-U has a cross-coupled design that accommodates adjacent channels, meets stringent filtering standards and provides constant impedance performance in adjacent channel applications as well as channel separations greater than 15 channels.
The RWED-516-U features the high isolation of traditional constant impedance technology but achieves elliptical response without external coupling mechanisms. The large cavities of the RWED-516-U can handle high power with low insertion loss, and the filters are temperature compensated for close-spaced combining applications. The RWED-516-U also is expandable to handle future channels.
