Procom DPF VHF/33
DESCRIPTION :
- The DPF VHF/33-DR 3000 is a 6-cavity duplex filter designed to be built into the Motorola DR 3000 duplex base station / repeater.
- This duplexer is delivered in a low-band version,
- DPF VHF/33-DR 3000-L, tunable within 138 - 156 MHz, and a high band
- version, DPF VHF/33-DR 3000-H, tunable within 152 - 175 MHz.
- The duplexer can delivered with 4 - 10 MHz spacing.
- The DPF VHF/33-DR 3000 is primarily intended for TX and RX operation on single frequencies, but it can also, however with slightly reduced data, be used where the TX and RX operate on several channels, i.e. within a certain port bandwidth. In the latter case, factory tuning is recommended.
- The filter has very small physical dimensions due to the use of high-Q, temperature-compensated helical resonators in a compact, extruded aluminium housing. The chassis is made of passivated steel, and teflon insulation has been applied in the coaxial cables and in the connectors.
- The filter is coated with black vinyl to prevent corrosion.
