Ku-Band Airborne BDC

Product catalog summary

Overview
Orbital's Ku-Band Airborne Block Downconverters (BDCs) are designed for reliable in-flight connectivity, supporting extreme environmental conditions on aircraft. They are available in two versions: fixed local oscillator for a single Ku region and multiple local oscillator for multiple Ku regions. These BDCs are characterized by high data rate applications with low bit error rates.

Key Features

External reference for stability
Low phase noise for maximum data throughput
Preset signal gains from 20 to 45 dB
Linearity for higher-order modulation schemes
Temperature options up to 70°C

Applications
These BDCs are suitable for military and commercial airborne SATCOM applications, providing reliable in-flight Wi-Fi, communication, and entertainment. They are built to AS9100 standards for high altitude, high vibration environments, and extreme thermal cycles, operable in-cabin or externally with antennas.

Ku-Band Airborne BDC • External referenced for stability • Low phase noise for maximum data throughput • Preset signal gains from 20 to 45 dB • Linearity for higher-order modulation schemes • Options for temperatures up to 70°C Our airborne block downconverters (BDCs) for Ku-band are built to support reliable in-flight connectivity and meet the extreme environmental conditions on aircraft. They come in two versions: fixed local oscillator (for a single Ku region) and multiple local oscillator (for multiple Ku regions). Like all Orbital BDCs, they enable high data rate applications with very low bit error rates. These BDCs are for military and commercial airborne SATCOM applications and can help customers provide reliable in-flight wifi, communication and entertainment. Built to AS9100 standards, they are designed for high altitude operation, high vibration environments and extreme thermal cycles – and can operate either in-cabin or externally with the antennas. Unlike an LNB, BDCs are used after an external low noise amplifier (LNA). This means you can connect multiple BDCs to a single LNA without affecting the noise figure of the system. BDCs let you receive signals from the entire satellite spectrum – with IF outputs at appropriate frequencies for your demodulators.
