    Tuneable UHF Cavity Bandpass Filter, Description

    This Tuneable UHF Cavity Bandpass Filter is a very sharp, narrowband, inline filter designed to enable communications where strong in-band signals exist, where a high degree of man-made noise prevents reliable communications, or where cohabitation with other transmitters is required. The UFL-0300-673 can be tuned to the intended operating frequency within frequencies spanning 225 MHz to 400 MHz (Aviation, Military UHF LOS bands).

    Use this filter when operating in challenging or hostile Electromagnetic environments, such as Airports, to relieve Air Traffic Control radio equipment's front end from having to contend with large amounts of integrated power or nearby transmissions, which can lower receiver sensitivity and produce undesirable intermodulation products. Additionally, use it to keep your emissions clean from spurious components affecting nearby communications of others.
