CBA 100M-400

10 kHz to 100 MHz 400 Watt Class A Broadband Amplifier

CBA 100M-400zoom
  • Class A linear and low distortion design
  • Ideal for low frequency tests using various strip line devices
  • Mismatch tolerant and unconditionally stable
  • Rugged design for EMC testing
  • Three year parts and labour warranty

This low frequency amplifier can be used in conjunction with other amplifiers from the Teseq range to cover the entire frequency range from 10 kHz to 40 GHz with convenient frequency break points allowing you to optimise the power level in each range.

The Class A 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. A safety interlock connector is provided, which the user can short circuit to ground, to put the amplifier into standby mode. Front panel indicators are provided to indicate over-temperature and rf interlock operation.
