Reject Filters with 5” & 8” Cavities Horwin RF-V/Ux-x series is a reject (notch) filters based on a quarter wave 5 or 8 inches width square cavities. The use of large cavities provides a high input power rating and means high Q, resulting in a very narrow pass or reject spacing. Filters allow to handle up to 200 watts power. There are single or dual cavity filters available. More cavities provide greater rejecting, when required, a wider notch. Filter nominal impedance is 50 Ohms. N-type “female” connectors are used for input/output connections. Cavities are aluminium made with 5 mm thick top plate welded to the cavity body. Inner conductor and coupling loops are silver plated cooper made. Central tuning road is invar made. All this provides excellent frequency stability in temperature range from – 30 to + 60°C. Filters are tuned for customer specified frequencies and no further adjustments should be required. RF reject filter x frequency range (U=UHF, U=UHF) x cavities numbers x cavity width (inches)
