Jampro Antennas introduced the UHF RWED-516-U compact TV mask/filter combiner. It incorporates four-port directional filter/combining that can be used either as a mask filet, 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 unit features the high isolation of traditional constant impedance technology, but achieves elliptical response without external coupling mechanisms. The large cavities can handle high power with low insertion loss, and the filters are temperature compensated for close-spaced combining applications. Not limited to bandwidth restrictions of standard hybrid technology, the RWED-516-U is expandable to handle future channels.
