DPF 2/33-250-WM

Filtres DuplexDPF 2/33-250-WM

Duplex Filter for the 150 MHz Band

Description

  • High power base station duplex filter for the 140 - 175 MHz range.
  • The use of large ø250 mm cavities means a high Q, resulting in a very narrow duplex spacing.
  • The large dimensions also mean a high power rating.
  • Unloaded Q of a single cavity is approx. 8000.
  • High frequency stability on temperature and power.
  • Suitable for Wall Mounting (WM) by opening the Duplexer and have all 6 cavities in a row, so they can be attached with screws through the brackets and into the wall.
