AR Modular RF has completed production on 80 units of its Model KAW5050 amplifier for a base station application. The KAW5050 is a Class AB wideband RF power amplifier system delivering up to 1000 Watts PEP power into a 50-ohm load over the frequency range of 225 MHz to 400 MHz.
This new custom system comprises a power amplifier, controller sub-system and AC power supply unit encased in a 3-RU shelf. The system weighs 50lbs and mounts into a standard, 19in equipment rack. The new amplifier is being used in a base station application and can be operated and monitored remotely via RS232 or ethernet control.
Replacing a legacy two-shelf, 500W, 225MHz – 400MHz, 115lbs-rack mount system, the new configuration utilises updated components and design techniques for a lighter, more powerful, more efficient system.
