Compact Pass-Reject Filters Horwin PRF-V/UM6-x series is a compact “band pass – band reject” filters based on a 6 full size quarter wavelength resonator on UHF and helically on VHF. This filter types can be used to protect a receiver against interference from a nearby transmitter. Pass/reject filters are irreplaceable when the spacing between RX frequency and the interfering signal so small, that the slop of normal pass filters or reject filters are not sufficient to provide adequate rejections. Filters allow to handle up to 50 watts power. Filter nominal impedance is 50 Ohms. N-type “female” connectors are used for input/output connections. The filter’s cavities are made of extruded aluminium. All coaxial cables used are semi-rigid silver plated. Cables and connectors are with PTFE insulation. Filters are covered with black polymer powdered coating. Filters are tuned for customer specified “pass” and “reject” frequencies and no further adjustments should be required.
