Datasheet Accessory Kit

Designed specifically for radiated EMC Testing, this mismatch tolerant Class A amplifier delivers power continuously into the very poor match typically associated with broadband EMC antennas when used at low frequency.
 

The GaAs 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 use of gallium arsenide technology represents a breakthrough in amplifier design for this frequency range and output power.
 

This 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 withintegral fans, and is protected against faulty cooling by excess temperaturesensing. 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 indicated over-temperature and rf interlock operation.
