Filters are essential communication devices used in telecommunication and other applications in various frequency ranges. High frequency crystal filters are used in wireless and telecommunications applications. These filters are ideally suited for signal processing, low power transmitters or harmonic filters. For signal processing applications where high dynamic range is required these filters are ideal. The high power rating and careful design yields extremely high intercept points. Vhf filters are contained in a heavy-duty nickel-plated brass enclosure to provide an excellent shielding against magnetic and electrical signals. Vhf/fm & uhf band-pass filters provide extremely high rejection of out of band signals, adjacent channels.They utilize a high-q, six-stage bandpass filter and two-phase cancellation traps to provide excellent rejection of out of band signals. These filters pass a single uhf channel and offers excellent rejection of all channels outside the bandpass of the filter.
