AR Modular RF to Deliver Lighter, More Powerful, More Efficient Amplifier Systems to AT&T
2013-06-11 06:00:00| Industrial Newsroom - All News for Today
Bothell, WA -- AR Modular RF has received an order from ATT Inc. for 80 systems using its KAW5050 power amplifier. The 1000-Watt PEP, 500-Watt CW, amplifier covers the 225- 400 MHz frequency range. The custom system ordered by ATT 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 ...This story is related to the following:Electronic Components and DevicesSearch for suppliers of: Power Amplifiers
