Empower RF Introduces 1kW X-Band Pulsed SSPA for Extending Radar Range

Empower RF has introduced a GaN Solid State PA pulse emitter designed for radar applications where portability and extended range are key requirements. 

The model 2241 provides over 1000 W of peak power from 9 to 10 GHz in a compact 3U chassis. Flexible waveform handling is a key feature of this amplifier. It is capable of long pulses, high-duty cycles, and a derated long pulse mode. The unit is controlled through the front panel touch screen, M2M SCPI, and peer/LAN connected PC & web browser with no software to install.

The 2241 is suitable for pulse applications in the X-band frequency. This amplifier utilizes high-power GaN on SiC devices that provide wide frequency response, high gain, high peak power capability, and low distortions. Exceptional performance, long-term reliability and high efficiency are achieved by employing advanced broadband RF matching networks and combining techniques, EMI/RFI filters, and all qualified components. The amplifier is constructed within one single 3RU drawer including the forced air-cooling. Available operating voltage configurations are single phase 100-240 VAC up to 400Hz and 28 VDC.

The amplifier includes a built-in control and monitoring system, with protection functions that preserve high availability. Remote management and diagnostics are via an embedded web server allowing network-managed site status and control simply by connecting the unit’s Ethernet port to a LAN. Using a web browser and the unit’s IP address (IPV4) allows ease of access with the benefit of multi-level security. The control system core runs an embedded OS (Linux) and has a built-in non-volatile memory for event recording and factory setup recovery features. The extended memory option allows the storage of control parameters and event logs. Empower RF’s ISO9001:2015 Quality Assurance Program assures consistent performance and the highest reliability.
