            Lambda TPF-V2-8                 144 -174 MHz




           Lambda  TPF-V2-8    is a VHF  band pass  filter based on




           a quarter length  8 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.
