The 2244 from Empower RF Systems is a Solid-State Pulsed Power Amplifier System that operates from 1 to 1.4 GHz. It delivers a pulsed output power of more than 8 kW with a power gain of 74 dB and has a duty cycle from 0.5 to 20%. This amplifier system comprises multi-drawer integrated subsystems which feature multiple high-power GaN-on-SiC devices that can be used to provide wide frequency response, high gain, high peak power, and low distortions. It can be scaled up in power by using (stacking) multiple building blocks (amplifiers). Each amplifier “building block” has a full gain PA with an integrated single-phase power supply and liquid cooling in a 2U chassis. The power combining feature with hot-swapping provides an affordable upgrade path for mission-critical applications.
The 2244 includes built-in control and monitoring systems, with protection functions that preserve maximum output availability and reliability. Remote management and diagnostics can be done via an Ethernet port and 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), and has a built-in non-volatile memory for factory setup. It is available in a rackmount enclosure that measures 40U in height and 40” in depth with an N-Type (female) input connector and EIA 1-5/8 output connectors.
This amplifier requires a 3-phase AC supply of 208 V and consumes less than 10 kVA of power.
