The 2239 from Empower RF Systems is a Solid-State Class AB Pulsed Power Amplifier System that operates from 2900 to 3500 MHz. This amplifier is available in a compact 3U rack compatible footprint with features ideal for integrating into Magnetron, IoT, Klystron, and TWT systems. It delivers 1000 W of peak pulsed output power and has a gain of more than 65 dB. The amplifier has a duty cycle from 0.5 to 20 %, a pulse width from 1 to 500 μs, and a pulse rise/fall time of 70 ns.
The amplifier is designed for 0 dBm input that is pulse-modulated. A fast TTL gate input is standard, and it’s use optional when complete shutoff of the output stage is desired between pulses. It utilizes high power GaN on SiC devices that provide wide frequency response, high gain, high peak power capability, and low distortions. It has an embedded directional coupler that eliminates the need for external components.
The amplifier system includes a built-in control and monitoring system, with protection functions that preserve maximum output availability and reliability. Remote management and diagnostics can be done via an Ethernet port to LAN. The system can be controlled remotely by a web browser or M2M (machine to machine interface) or locally by a panel computer. The control system runs an embedded OS (Linux), has a built-in non-volatile memory for factory setup. It is available in a rack-mount enclosure that measures 17 x 5.25 x 22 inches with N-Type, SMA and BNC female connectors and is suitable for pulse and CW applications.
