Filters & Duplexers

Low loss filters are used to filter closely spaced transmitters and receivers into one antenna. Using a filter/duplexer minimizes the required tower space, provides transmitter to transmitter isolation, and reduces intermodulation interference. Freedom Microwave filter/duplexers are temperature compensated to ensure frequency stability and minimize system degradation.
