They will build a 160W solid-state, gallium nitride power amplifier for communications, electronic warfare and radar applications.

The technology will replace older vacuum tubes, known as travelling wave tubes, which are currently used to produce high-power radio frequency signals.

The first prototypes of the amplifiers could be in use by the end of the decade, BAE says.
