L-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) and new Series 2 (S2) have a spurious-free dynamic range (SFDR) with an extra 4 and 5 dB/Hz respectively over the standard ViaLiteHD product. The increase in SFDR allows an extra 5 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.
- S1 has a 5 mW laser and S2 is 12 mW
- 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

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.
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.
The L-Band HTS – HWDR links are suitable for:
- Full satcom transponder applications
- Defense Signals Intelligence (SIGINT)
- Fixed satcom earth stations and teleports
- Government installations
- Remote monitoring stations.
– Single rack chassis card (Tx) – Series 1 & Series 2
A fully populated 19” 3U ViaLiteHD rack chassis supports up to 26 links and accepts 13 RF cards, plus an SNMP card and dual power supply modules. A 1U chassis accepts three RF cards or two RF cards with an SNMP card.
