LGAN C- or Ku-Band Block Up Converter (BUC)/SSPA

Our extensive experience in the design of outdoor Block Up Converters led to the GaN-based LGAN family’s efficient thermal andmechanical package. Recognizing the evolution of L-Band IF systems, the LGAN is designed to eliminate the traditional requirement for the modem to supply a DC power source and a 10 MHz reference to the BUCs and LNBs. The LGAN’s optional internal reference and LNB bias T greatly simplify multi-carrier operation and provide cost-effective redundant solutions. The LGAN offers valuable features not found in other L-Band BUC products. Multiple power levels are offered, up to 500W in C band and 400W Psat rated in Ku band.

Optimized for Multi-Carrier/Multi-Transponder Operation

When used for Multi-Carrier/Multi-Transponder applications, Gallium Nitride power
devices historically have caused problems with intermodulation performance. The
LGAN addresses this challenge and is available with two options:
• Option 1 – Optimized to provide the maximum linear power possible for single
carrier applications
• Option 2 - Provides virtually the same intermodulation performance whether the
carriers are 5, 50, 150(or more) MHz apart

Optional Single and Multi-Band LNB Support

The LGAN was designed with the evolution of L-Band systems in mind. No longer relegated to low power single carrier installations, L-Band IF topologies are now found in larger multi-carrier installations. A challenge presented by multi-carrier L-Band systems is the presence of DC and reference components on the TX/RX L-Band interfaces. The LGAN design, by default, eliminates the DC component from the TX IF and can eliminate the reference requirement with the optional internal OCXO. The LNB bias/reference option completes the solution by eliminating DC and reference signal requirements from the RX L-Band interface. We also offer a high-stability “Multi-Band” Ku LNB facilitating global Ku-Band downlink coverage controlled by the LGAN M&C.
