Solid-State Radar Technology

The Industry Pioneer of Solid-State Power Amplifier Technology

EWR was the first company to commercially deploy SSPA transmitters in weather radar systems, beginning in 2006. Today, EWR is the world’s leading supplier of SSPA-based weather radar systems, with more systems installed globally than any other manufacturer.

SSPA (Solid-State Power Amplifier) is a transmitter technology that generates and amplifies RF energy using semiconductor technology rather than vacuum tubes. Unlike magnetron or klystron transmitters, SSPAs offer greater reliability, consistent performance, improved efficiency, lower maintenance, and reduced lifecycle costs.
