900 Duplexer for 896-902 MHz and 935-941 MHz passbands
RFI’s range of compact multi-resonator milled aluminium band pass duplexers are ideal for use where space is restricted or at a premium. The relatively broad pass band characteristic, good duplex port to port isolation, high power and multicarrier capability make these ideal duplexers for either single carrier or combined multicarrier systems.
RFI’s range of compact multi-resonator milled aluminium band pass duplexers are ideal for use where space is restricted or at a premium. The relatively broad pass band characteristic, good duplex port to port isolation, high power and multicarrier capability make these ideal duplexers for either single carrier or combined multicarrier systems. The temperature stable resonators provide a wide operational temperature range ensuring important electrical specifications such as insertion loss and Tx port to Rx port isolation are maintained.
Features:
- 6MHz Pass Band low & high ports
- 39MHz Tx to Rx duplex split
- 100W (CW) Power rating
- Low insertion loss and pass band ripple
- 2RU 19” Rack mount front panel
- Compact temperature stable design
