DPF 70/4-100C-1.6N Duplexer Filter for amateur radio use pre-tuned to the requested frequency
With the new MISE circular of May 16th, the channel plan for Italian amateur radio repeaters will be modified. The only shifts (spacing between RX uplink and TX downlink) allowed will be 600 kHz in the VHF band (144-145 MHz), 1.6MHz in the UHF band (430-440 MHz), and 28 MHz in the UHF band (1200-1300MHz).
The 5 MHz (TX/RX) shifts in the UHF band (the most common ones) will be abolished.
This decision will require a significant portion of the installed repeaters (DMR/D-STAR/C4FM/Analog) to be adapted.
We have prepared this offer regarding the DPF 70/4-100C-1.6N Duplexer Filter with four cavities and an isolator in the UHF band (430-440 MHz) for 1.6 MHz spacing and with the following main features:
- TX/RX Isolation 100 dB
- RX Insertion Loss < 1.4 dB
- TX Insertion Loss < 1dB
- Dimensions Rack 19” 3U width 485 mm
- Height 135 mm
- Depth 265 mm
