Empower RF Systems will be at IMS 2024 (Booth 1730) to show off its Model 2254 S-Band pulsed transmitter. This air-cooled, high-power transmitter operates from 2900 to 3500 MHz and meets the demanding requirements of radar, electronic warfare, and directed-energy research applications.

With its peak power output of 15 kW, the 2254 is said to be one of the most powerful S-band transmitters in its class. Thanks to a duty cycle of up to 20% and pulse widths of up to 500 µs, this Class AB transmitter can drive sustained high-power pulses for extended periods, ensuring reliable performance in mission-critical scenarios.

The amplifier subsystem features multiple, high-power, gallium-nitride-on-silicon-carbide (GaN-on-SiC) power transistors that offer wide frequency response, high gain, high peak power, and low distortion. High reliability and efficiency are achieved through the use of advanced broadband RF matching networks and combining techniques, EMI/RFI filtering, and qualified components. Each drawer in the rack enclosure includes integral forced-air cooling. The system operates from 180 to 260 V AC, three-phase.

A built-in control and monitoring system includes protection functions, while remote management and diagnostics are handled via an Ethernet port to a LAN. Operators can manage functionality remotely using either a web browser or machine-to-machine interface, or they can use the system’s built-in touchscreen.
