            Lambda TPF-U2-5                400 - 470 MHz




           Lambda  TPF-U2-5    is a UHF  band pass filter based on






           a quarter length  5 inches width  two square cavity.  Using of





           large cavities  provides    a    high    input    power    rating   and


           means high Q (quality Factor),resulting in a very narrow pass band.
           The  cavity  design  provides  excellent frequency stability in









           temperature  range from – 30  to + 60  C°. Filters are tuned  for



           customer  specified  frequencies and  no  future adjustments  should

           be required.
