New LAM3D Process Reduces Production Time for Radar, Electronic Warfare Amplifiers

March 10, 2025

A new manufacturing process developed by U.S. startup Elve has reduced the production time of traveling-wave tubes (TWTs) from more than a year to several weeks. The process, called Layered Additive Multi-Material Manufacturing – Digitized (LAM3D), was created with support from the Defense Advanced Research Projects Agency (DARPA).

TWTs play a crucial role in high-frequency applications, including satellite communications, deep space communication, and electronic warfare systems. Traditional manufacturing methods for these components have faced limitations due to their complex design requirements and precise assembly needs.

The LAM3D process enables engineers to design and optimize TWT circuits in under two hours for various frequency bands, including Q-band (33–50 GHz), V-band (40–75 GHz), and E-band (60–90 GHz). These frequencies support advanced radar systems and high-speed communication networks.

DARPA’s Embedded Entrepreneur Initiative (EEI) provided additional support to help Elve develop its market strategy. The company subsequently secured $15 million in Series A funding to establish a commercial manufacturing facility.

The technology has now expanded to produce circuits operating above 200 GHz, addressing requirements for future communication and sensing technologies. This advancement aims to increase the availability of TWTs for both defense and commercial applications.
