HOrw1n Filter

Lambda TPF-V3-8 144 -174 MHz

Lambda TPF-V3-8 is a VHF band pass filter based on

a quarter length 8 inches width three 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.
