The Empower 1222 is a high performance X-Band pulsed GaN solid-state power amplifier (SSPA) designed for advanced radar applications. Operating in the 9 to 10 GHz frequency range, this compact module delivers over 250 W peak power, making it ideal for portable radar systems requiring extended range. This fielded and proven module is also used as a building block in Empower’s air- and liquid-cooled multi-kilowatt X-Band amplifiers.
Utilizing 48 V GaN-on-SiC technology, the Empower RF1222 offers exceptional efficiency and power density in a lightweight, reliable and rugged package. Its flexible design accommodates pulse widths ranging from 500 ns to 500 μsec with a duty cycle of up to 20 percent, providing versatility for various radar configurations. One of the standout features of the Empower 1222 is its rapid response time, with an enable/disable time of less than 250 ns.
The amplifier offers an RS-485 digital interface for control and monitoring in state-of-the-art implementations. To accommodate legacy implementations, the module also provides an analog interface. This flexibility, combined with its compact form factor, makes the Empower 1222 well-suited for new radar applications where portability and extended range are key requirements.
The 1222 offers comprehensive protection features to ensure optimal performance and reliability. These include safeguards against excessive pulse width or duty cycle, over temperature, power supply overvoltage, reverse polarity and overcurrent conditions. Empower RF has designed this SSPA to meet the demands of contemporary X-Band radar applications, offering a COTS solution that balances high performance with reliability. The Empower 1222 represents a significant advancement in radar technology, enabling longer-range detection and improved system capabilities in a compact package.
Empower RF Systems designs RF and microwave power amplifier solutions for EW, radar, satcom, threat simulation, communications and product testing.
