For more than 45 years, L-3 Communications Electron Technologies, Inc. (ETI), (formerly Hughes Electron Dynamic Devices, Inc.), has been a leading supplier to the space and defense industry. Historically known for our top performing traveling wave tubes (TWTs) electronic power conditioners (EPCs) and fully integrated TWTAs, ETI has broadened its capabilities and now offers space-qualified state-of-the-art Xenon Ion Electric Thrusters and power processing units.

In the space market, ETI serves both the Government and Commercial segments while in the non-space market ETI provides products critical to the Airborne and Surface Radar, Military and Commercial Communications and Instrumentation segments.

With its traditional product lines, ETI has delivered more than 4,700 space TWTs and 2,100 TWTAs to customers worldwide. Our space-qualified products range from L-band to V-band with output powers from .5 to more than 250 watts. In the non-space markets, ETI has delivered over 20,000 TWTs and is recognized as the leader supplying high power coupled cavity TWTs over the frequency range from C-band to Q-band and millimeter-wave helix TWTs for SATCOM radar and instrumentation applications. All modern designs incorporate this unparalleled experience ensuring high reliability, and optimized performance in harsh environments.

More recently, ETI has extended its industry-leading capabilities into the electric propulsion arena by being the exclusive supplier of the Xenon Ion Thrusters (XIPS) and Power Supplies for all Boeing 702 spacecraft and a major player in NASA's Deep Space programs including Deep Space One.

ETI is unique. We design, develop, fabricate, integrate and test each product at our fully integrated facility in Torrance, California. This greatly benefits our customers by streamlining the procurement process, reducing costs and cycle times, and assuring an end item that meets or exceeds performance requirements.

ETI Space Heritage

For more than 45 years, ETI has been recognized as the industry's leading manufacturer of TWTs, EPCs, and TWTAs, We have delivered thousands of TWTs and TWTAs to customers worldwide. Our products range from UHF-band to V-band and modern designs incorporate this unparalleled experience ensuring high reliability and optimized performance.

With hardware on more than 180 satellites, over 450 million TWT operating hours in orbit, and more than 142 million EPC/TWTA operating hours in orbit, ETI's product lines have a proven history of high reliability. With ETI hardware on the majority of the world's commercial geosynchronous communications satellites, the cumulative operating hours continue to rise while the observed failure rate decreases as modern heritage designs replace those from past generations.
