sales@vialite.comL-Band HTS 400-2500 MHz – HWDR
The ViaLiteHD L-Band HTS Hyper Wide Dynamic Range (HWDR) links have been designed for those needing an even greater dynamic range.
The Series 1 (S1) has a spurious-free dynamic range (SFDR) with an extra 4 dB/Hz respectively over the standard ViaLiteHD product. The increase in SFDR allows an extra 4 dB of dynamic range for High Throughput Satellites (HTS) transponder bandwidths of 500 MHz, 800 MHz or even 1500 MHz. This allows customers to improve intermodulation performance and reduce the minimum signal that can be detected – extremely important in HTS and Signals Intelligence (SIGINT) applications.
- Covers 400-2500 MHz with up to 115 dB/Hz2/3 SFDR
- Transmission distances of 0-100 km (DWDM)
- Ideal for 500, 800 and full 1500 MHz bandwidths used in HTS
- RF and fiber connections on the rear
- 13/18/22 V and 22 KHz tone LNB control
- 50 ohm
- Superior linearity and low noise
- SNMP or web GUI interface for easy set-up, remote monitoring or control
- 5-year warranty as standard

Product Inquiry
Hyper-wide dynamic range
The HWDR link allows a wider dynamic range signal to be transported.
Plug and Play
The links can be either plug-in or blind mate and are completely plug and play, enabling simple installation.
The rack chassis cards can be positioned in any slot of a ViaLite 19” rack and can be mixed with standard L-Band HTS, 70-140 MHz, 10 MHz and in Tx and Rx configurations.
Blind Mate
The chassis cards are available with the ViaLiteHD blind mate option, which allows all cables to be connected at the rear of the chassis when installed. It also allows configuration changes to be completed without disturbing the connections and very fast changeover of cards; enabling five 9s reliability.
1:1 Redundancy
To ensure five nines reliability, the links are available in a full 1:1 redundancy configuration, in both rack mount and outdoor enclosures, using ViaLite splitters and switches.
Other link options include L-Band HTS + Reference links (integrating 5-50 MHz reference signals) and ViaLite Long Distance DWDM links, which cover distances between 0-600 km.
Series 2 (S2)
Please see End of Life Products for details on the Series 2.
The L-Band HTS – HWDR links are suitable for:
- Full satcom transponder applications
- Defense Signals Intelligence (SIGINT)
- Fixed satcom earth stations and teleports
- Telemetry
- Government installations
- Remote monitoring stations.
Hardware formats
