Empower Releases Solid State RF Transmitter for Radar and EW Applications

Empower RF Systems has developed the Model 2244, a long-duty cycle, pulsed transmitter operating from 1 to 1.4 GHz, designed for maximum waveform flexibility. Configured for EW and L-Band radar applications, the 2244 is the newest member of Empower’s technologically advanced liquid-cooled and scalable architecture. This new modern architecture offers scalability for affordable upgrade paths to future power needs by adding hardware to an existing system.

The 2244 transmitter layout consists of a system controller in a 3U 19-inch rack unit and 6 (expandable up to 16) hot-swappable 2U amplifier drawers with each amplifier drawer containing an integrated power supply in its 2U chassis. There is no separate system-level power supply. This arrangement eliminates the risk of an RF section or single power supply failure taking the entire amplifier offline. In the event of an RF pallet or PA booster failure, only a fractional reduction of output power is realized, and the amplifier system remains on air. These Fast Field Replaceable (FFR) drawers allow hot or muted swapping with less than 15 minutes MTTR. Watch a demonstration of fast field replacement of a PA booster in the video below. The result is a system with extreme Effective MTBF.

Breakthrough in Complex Waveform Handling

Sophisticated digital input and output RF detection algorithms measure Peak, RMS, and Envelope. Digital processing of the detectors allows capabilities not previously found on COTS pulse amplifiers. 

Key Features of 2244:

  • Asymmetrical/Random Pulse Widths and Duty Cycles
  • 500KHz PRFs and 20% Duty Cycles
  • 200ns to 500usec Pulse Widths
  • Droop Correction Option Available
  • CW operation – up to 2KW
  • Optional Capability for Digitally Modulated Signals on the Pulse Carrier
