ESCRIPTION
The Terrasat outdoor unit (ODU) consists of an intelligent block upconverter (Cyber
Hardened IBUC
2
, IBUC
2e
, IBUC
2
G
, IBUC
R
or IBUC
G
), power supply unit
(PSUI), and low
-
noise block converter (LNB) for use in satellite earth stations. The
outdoor equipment is designed to interface directly with an L
-
band satellite modem.
Introduction
This chapter contains detailed information about the various system components of the
following Cyber Hardened IBUC models:
• IBUC
2
: All of the original features of the IBUC but in a smaller, more
cost
-
effective package that is ideal for applications where compact size, light
weight, and low thermal dissipation are critical factors.
• IBUC
2e
: The low energy consumption model of the IBUC
2
, intended for use
with modems with limited capacity power supplies and where DC power is
supplied only via coaxial cable.
• IBUC
2
G
: The compact physical size of the IBUC
2
powered by gallium nitride
(GaN) technology. GaN devices like the IBUC
2
G
can operate at much higher
temperatures and work at much higher voltages than GaAs devices.
• IBUC
R
: All of the original features of the larger IBUC package with an RJ45
Ethernet connector.
• IBUC
G
: Higher power IBUC in large enclosure powered by gallium nitride
(GaN) technology.
