Note : Your request will be directed to Empower RF.

The 2238 from Empower RF Systems is a Solid-State Class AB Pulsed Power Amplifier System that operates from 2 to 4 GHz. This amplifier is a multi-drawer integrated subsystem which features multiple high power GaN devices that can be used to provide wide frequency response, high gain, high peak power, and low distortions. Each drawer is a full PA with an integrated single-phase power supply and liquid cooling. It features gain and phase control and is fully hot-swappable in case of failure.

The 2238 delivers more than 12 kW of peak pulsed output power and has a gain of more than 76 dB. The amplifier has a duty cycle from 0.5 to 20 %, a pulse width from 0.2 to 500 μs, and a pulse rise/fall time of 25 ns. It has a 2nd harmonic of -40 dBc and spurious of -60 dBc.

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 rackmount enclosure that measures 40U in height and 40” in depth with N-Type Female input and WRD-200 output connectors.
