Using
Orbital Systems Interface Products to bring 4 BDCs, 16 Modem/Receivers and a BUC,
under the discipline of a single 10 MHz Oscillator.
The client needed multiple receivers/modems to
cover 2 GHz of bandwidth (10.7 - 12.75 GHz). For each polarity, a wide band
LNA, a highband BDC, and a lowband BDC were required. System performance
required instant acquisition, high stability, and optimal BER, therefore
external reference BDCs were needed. The same high quality conditions
were required to be met for the uplink.

Here is a redundant horizontal/vertical
polarity solution using Orbital's Systems Interface Products to route
the satellite signals. This project includes both indoor (IDU) and
outdoor segments (ODU).
One for two redundant LNA's, horizontal and vertical high/low
BDCs all controlled by the same Orbital Master Oscillator and combined for
output to various client devices. All of the BDCs are in weather-tight
enclosures out at the dish and are linked to the IDU through the IFL cable.
