Ku-Band Iso-Dividers™



Ku-Band Iso-Dividers

Ku-Band Iso-Dividers combine the functions of high-performance power dividers (or combiners) with ferrite isolators. These new devices have exceptional insertion loss and band flatness performance in a small, lightweight package while providing the high reliability that is crucial for space applications. They are designed for satellite receiver or transmitter redundancy applications, without introducing complex switch-based solutions.



  • Combines power dividers (or combiners) and ferrite isolators functions in a single package

  • Solves passive satellite redundancy in receive and transmit applications

  • High port isolation with low insertion loss

  • Reduced size and weight than an equivalent discrete assembly – average 60% volume reduction

  • Better overall performance than separate devices

  • Fewer components for lower assembly cost and higher system reliability

The Making of the Ku-Band Iso-Divider


Crane’s Ku-Band Iso-Divider is unlike anything else on the market today, and it’s all thanks to a conversation with a customer. The customer wanted a way to directly connect power dividers with isolators, both of which are usually acquired separately. Crane’s engineers realized that this could be simplified, and designed a new product that combines both functions in a single, significantly smaller package.


Available in 2-way, 4-way, and 8-way configurations, the Ku-Band Iso-Divider product family demonstrates Crane’s commitment to innovation and customer satisfaction.
