ASELSAN Interference Blanking Unit

Aselsan Interference Blanker Unit (AIBU) is used on military platforms to prevent interference between the numerous onboard RF systems. AIBU can be tailored to meet any application and is programmable to simplify system design.

AIBU provides a novel blanking system that can be quickly modified and adapted to varying flight configurations. For military aircrafts, such flexibility in adapting the blanking system into the aircraft is a very desirable feature.

With its reliable and rugged design, the AIBU operates in severe environmental conditions on fixed-wing and rotary-wing platforms with advanced cooling and thermal management techniques.
