16 Hot Swappable 2U Amplifier Drawers

Empower RF Systems' Model 2237 1 to 2 GHz, 40 kW Transmitter
for Radar, Test, and EW
August 25, 2022 - Inglewood, CA - Empower RF Systems
Model 2237 is a high performance, liquid cooled, pulsed transmitter operating
from 1 to 2 GHz, designed for maximum waveform flexibility. Another variation of
Empower's Gen3 platform, the 2237 is configured for L-Band radar, test, and EW applications.
The deployment of the 2237, along with the previously announced 2244, further solidifies
the solid state, high power, liquid cooled L-Band product baseline that has been
developed. This new modern architecture offers scalability for affordable upgrade
paths to future power needs by adding hardware to an existing system.
The 2237 transmitter layout consists of a system controller in a 3U 19-inch rack
unit and 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. You can watch a demonstration of fast field replacement
of a PA booster at the video link included below.
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:
- Random Pulse Widths and Duty Cycles
- 500 kHz PRFs and 10% Duty Cycle
- 200 ns to 500 usec Pulse Widths
- Droop Correction Option Available
- Optional Capability for Digitally Modulated Signals on the Pulse Carrier
