80 W Ku-band GaN BUC - Communications & Power Industries

80 W Ku-band GaN BUC
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
Model 4980L
80 watt Ku-band GaN BUC
for satellite uplink applications
•Internal or multiplexed 10 MHz reference
•Multi-band BUC: select from multiple
factory-set frequency bands within
•1:1 Redundant Switching
Protects against high temperatures, open/short/overdrive
RF output conditions, INT/EXT reference 10 MHz conditions,
prime power fluctuations. RF output overdrive protection
prevents damage from higher than rated input power.
Global Applications
Meets Electromagnetic Compatibility Directive 2004/108/EC
to satisfy worldwide requirements and is CE-marked.
Worldwide Support
Backed by over 35 years of satellite communications
experience, and CPI’sworldwide 24-hour customer
support network that includes more than 20 regional
factory service centers.

Configuration Guide
80 W Ku-band GaN BUC
Configure your 4980L GaN BUC
Configuring your BUC is easy. For this product, most of the configuration is
predetermined. All that is left is to indicate which frequency range is needed, and
whether the internal reference option is required. Instructions follow:
Box 3: Frequency range (within Ku-band)
- Enter “S” for 14.00 to 14.50 GHz
- Enter “E” for 13.75 to 14.50 GHz
Box 7: Internal reference
-Enter “R” only if internal reference option is selected
-LEAVE BLANK if internal reference option is not selected
_ AC /
_ CE _
Examples: 4980L-W/S-AC/EX-CE-R indicates a BUC with a frequency
range of 14.0 -14.5 GHz and internal reference. 4980L-W/E-AC/EX-CE
indicates a BUC with a frequency range of 13.75 to 14.5 GHz and with no
internal reference.
Notes: Box 2 indicates a waveguide RF output connection. Box 4 indicates that
this product is AC powered. Box 5 indicates that power is fed via an external
connector. Box 6 indicates that this product is CE marked.
