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

Ku-Band
40 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
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.

Configuration Guide
40 W Ku-band GaN BUC
Configure your 4940L 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, what
type of operating voltage is required, and whether the internal reference option is
required. Instructions follow:
Box 2: Frequency range (within Ku-band)
- Enter “S” for 14.00 to 14.50 GHz
- Enter “E” for 13.75 to 14.50 GHz
Box 3: Operating Voltage
-Enter “48” for 36 to 60 V DC powered
-Enter “AC” for AC powered
Box 6: Internal reference
-Enter “R” only if internal reference option is selected
-LEAVE BLANK if internal reference option is not selected
