Lambda TPF-V1-8 144 -174 MHz
Lambda TPF-V1-8 is a VHF band pass filter based on
a quarter length 8 inches width single 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.
