2-14 | Cyber Hardened IBUC 2, IBUC 2e, IBUC 2G, IBUC R, IBUC G Operations Manual: Functional Description
Engineered to Endure
Note: (G) marker stands for IBUC models that use GaN technology for power amplification
and required different fuses than regular GaAs amplifiers
Note: For IBUCs that require fuses up to 6.3 A, Terrasat recommends time lag fuse with a
high I
2
t value. For IBUCs that require fuses greater than 6.3 A, Terrasat recommends
time-delay fuses.
For reference, IBUCs are delivered with one of the following Littelfuse Series fuse:
