Typical response curve for 500 kHz Duplex
DPF 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.
