About Stellant Systems
Stellant Systems Inc. is a manufacturer of microwave devices for ground-based, airborne and satellite communications and radar. In October 2021, Stellant systems was formed from L3Harris Technologies' Electron Devices and Narda Microwave-West divisions when both were sold to Arlington Capital Partners, a Washington D.C. based private equity firm. The company was initially formed from the former Electron Devices Division (EDD) of the Industrial Electronics Group of the Hughes Aircraft Company, and from Litton Industries' Electron Division, both of which were acquired by L-3 Communications Holdings, Inc. L-3 later merged with Harris Corporation in 2019 to form L3Harris Technologies which was followed shortly by both divisions' sale to Arlington in 2021. Stellant is known for their traveling-wave tubes (TWTs), traveling-wave tube amplifiers (TWTAs), microwave power modules (MPMs) and electronic power conditioners (EPCs) as well as xenon gas ion propulsion systems (XIPS). Since its inception, EDD has produced tens of thousands of TWTs. They are the only U.S. supplier of space-qualified TWTs and TWTAs.
