Bothell, WA — June 11, 2013 — AR Modular RF has received an order from AT&T Inc. for 80 systems using its KAW5050 power amplifier. The 1000W PEP, and 500W CW, amplifier cover the 225- 400 MHz frequency range. The custom system ordered by AT&T comprises a power amplifier, controller sub-system, and AC power supply unit encased in a 3 RU shelf. The entire system weighs 50 pounds. This unit mounts into a standard, 19-inch equipment rack. The new amplifier will be used in a base station application and can be operated and monitored remotely via RS232 or Ethernet control.
Replacing a legacy two-shelf, 500W, 225- 400 MHz, 115-pound rack-mount system, the new configuration utilizes updated componentry and design techniques for a lighter, more powerful, more efficient system.
