CBA 400M-260

10 kHz to 400 MHz 260 Watt Class A Broadband Amplifier

CBA 400M-260zoom
  • Class A linear and low distortion design
  • High reliability gallium arsenide technology
  • Mismatch tolerant and unconditionally stable
  • Wide instantaneous bandwidth
  • Remote control option
  • Three year parts and labour warranty


Designed specifically for automotive, military and aerospace BCI and other susceptibility EMC testing,this mismatch tolerant Class A amplifier delivers power continuously into the varying match typically associated with this type of testing.

The GaAs Class A push pull design ensures a high reliability, low distortion linear performance across the frequency range. This design also ensures that the amplifier will continue to operate at full power even when presented with an open or short circuit at its output.

The unit is powered from a switched mode power supply for high efficiency, high power factor and wide voltage range operation. The unit is air-cooled with integral fans, and is protected against faulty cooling by excess temperature sensing. For added flexibility, two safety interlock BNC connectors are provided on the rear panel which allows either short circuit or open circuit to mute the output from the amplifier. Front panel indicators are provided to indicate over-temperature and rf interlock operation.
