Can be employed as either a mask filter or a constant impedance combining module for high power UHF broadcast. The compactness of this deviceallows for combining of multiple signals while taking up a minimum amount of space. The structure of this device affords it the ability to provide constant impedance performance in adjacent channel applications as well as channel separations greater than 15 channels. Filters of this design have been used for many years in higher frequency space applications now they are available for broadcast. The RWED filter is a constant impedance four port device that has all of the attributes of a constant impedance mask filter/combiner.
- · Compact design that is easily mounted in the overhead
- · High isolation synonymous with traditional style of constant impedance module
- · Elliptical response achieved without the use of external coupling mechanisms
- · Large cavities allow for high power handling and low insertion loss
- · Meter ports available both before and after the filter
- · Not limited to the bandwidth restrictions associated with standard hybrid technology
- · Combining systems are easily expanded to accommodate the addition of future channels
- · Temperature compensated filters for close spaced combining applications
