Custom Integrated Multi-Frequency Sources

 

Luff Research is pleased to present our multi-frequency source capabilities.

 We are specialists at integrating multiple frequency sources in one assembly.  We have developed sources that are highly integrated for system level applications and multiple sources for drawer level applications as well.

 We have a quick turn-around capability for custom designs.  Our products offer excellent performance at low cost and have a proven quality and reliability.
