4780 GaN BUC

C-Band
80 and 100 W C-band GaN BUCs
Compact and Lightweight
Designed and built with VSAT stabilized antenna platforms
and other similar satcom-on-the-move customer applications
in mind.
Highly Efficient
CPI has incorporated state-of-the-art Gallium Nitride (GaN)
HEMT technology into its popular and field-proven Mini-BUC
packaging. 30% to 50% more efficient than comparable
GaAs-based products.
Comprehensive M&C Functionality
Accessible anytime, anywhere via Internet or mobile phone.
Integrate with SNMP to NMS. Enables effective operational
management and minimizes network outage. Allows change
of IP address without serial cable. Dual LO, serial and
LAN interface.
Internal Self-Resetting Protection
Protects against high temperatures, open/short/overdrive RF
output conditions (forward and reverse), INT/EXT reference
10 MHz conditions, prime power fluctuations. RF output
overdrive protection prevents damage from higher than rated input power.

Configuration Guide
80 and 100 W Ku-band GaN BUCs
Configure your 4700 Series GaN BUCs
Configuring your BUC is easy. Much of the configuration is already predetermined.
All that is left is to indicate output power level, whether LAN interface is required,
which frequency range is needed, which type of prime power is required, and
whether the internal reference option is required. Instructions follow:
Box 1: Output Power Level/Model Number
- Enter “4780” for 80 W model
- Enter “4710H” for 100 W model
Box 2: LAN Option placeholder
- Enter “L” for BUCs with LAN option selected
- LEAVE BLANK if the LAN option is not selected Box 4: Output frequency range (within the C-band)
- Enter “S” for 5.850 to 6.425 GHz
- Enter “E” for 5.850 to 6.725 GHz
Box 5: Input power
- Enter “AC” for AC power
- Future Option: Enter “48” for 36-60 V DC input power
(contact CPI if required)
Box 8: Internal reference
-Enter “R” only if internal reference option is selected
-LEAVE BLANK if internal reference option is not selected
