8KW Pulsed L Band Transmitter with FFR

8KW Pulsed L Band Transmitter with FFR

Empower RF Systems Model 2244 is a long duty cycle, pulsed transmitter operating from 1 to 1.4GHz, designed for maximum waveform flexibility. Configured for 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 8 (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. 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 allow capabilities not previously found on COTS pulse amplifiers.
