Intellian CPI 40W Ka-Band Extended BUC (B3KO-B) VMT-1202

Ka-Band Signal Conversion and Amplification

The VMT-1202 performs two essential transmit-side functions within a maritime VSAT system. It converts the L-band signal received from the satellite modem into Ka-band and amplifies that signal before it reaches the antenna feed.

Its 40W saturated output rating supports installations that require more transmit power than lower-output Ka-band transceivers. The actual usable linear output depends on the waveform, operating frequency, temperature, and complete RF configuration.

Extended Ka-Band Operation

The B3KO-series platform is designed for operation across selected portions of the Ka-band satellite uplink range. CPI documentation for this equipment family identifies operation within the wider 27.5 to 31.0 GHz range, with the exact operating bandwidth and local oscillator configuration determined when the unit is specified.

The BUC must therefore be matched to the satellite network and antenna feed configuration. Two units with the same general power rating may not be interchangeable if their frequency plans or interfaces differ.

Designed for the Intellian v240MT

Intellian identifies the CPI B3KO-B VMT-1202 as the 40W Ka-band BUC option for the v240MT dual-band and tri-band maritime antenna platforms. These systems support Ku- and Ka-band operation, with the tri-band model also supporting C-band.

The VMT-1202 is an RF component rather than a complete satellite terminal. It requires the appropriate antenna, feed assembly, modem, control equipment, power source, and active satellite service.

Remote Monitoring and Control

The CPI B3KO platform uses microprocessor-based monitoring and control. Reference documentation for the product family identifies Ethernet monitoring, digitally controlled attenuation, transmit control, fault reporting, and serial-interface options.

These functions allow technicians to monitor operating status and assist with commissioning or troubleshooting without relying only on physical inspection of the antenna-mounted equipment.

Outdoor RF Installation

The BUC is designed for direct installation near the antenna feed, minimizing the high-frequency transmission losses that would occur if the amplified Ka-band signal had to travel through a long waveguide run.

The related CPI platform uses an outdoor housing with forced-air cooling and is designed for demanding environmental conditions. Installation should provide the required airflow, electrical protection, grounding, weather sealing, and access for service.

Professional Maritime Applications

The VMT-1202 is intended for engineered maritime VSAT installations, including:

• Cruise and passenger vessels
• Offshore production and support vessels
• Seismic and research vessels
• Commercial shipping
• Other high-bandwidth v240MT installations
