PRO DPF 70/6-5/7-N, 6-circuit duplex filter, frequency 406-500 MHz, duplex spacing 5-7 MHz, N coupler - specify frequencies

Order number: 7000 00753991

 

FEATURES/ADVANTAGES

 

• 50 W base station duplexer
• Both the ¼ λ models and the ¾ λ models are infinitely tunable from 406 MHz to 500 MHz.
• Low insertion loss thanks to silver-plated, temperature-compensated resonator elements in high-Q 40 x 40 mm cavities.
• Single-channel tuning as standard.
• Multi-channel tuning with slightly reduced data possible (factory tuning recommended).
• Fully environmentally tested.
• The DPF 70/6... is a duplex crossover with 6 resonators for duplex radio systems.
• The DPF 70/6... is adjustable in the complete 400 - 500 MHz band. The crossover is available in 4 different versions, depending on the desired duplex spacing (see "Type overview" below).
• The DPF 70/6... is primarily intended for Tx and Rx operation on single frequencies, but can also be used with slightly reduced data for Tx and Rx operation on several channels, i.e. within a defined bandwidth. In this case, a factory adjustment is recommended.
• The crossover is equipped with compact cavities in full ¼ λ length made of extruded aluminum. The chassis is made of demagnetized steel, the coaxial cables and connections are Teflon-insulated.
• The crossover is coated with black vinyl to prevent corrosion.
