Designed specically for radiated EMC testing, this mismatch tolerant Class A amplier delivers power

continuously into the very poor match typically associated with broadband EMC antennas when used

at low frequency.

Since antennas typically exhibit their lowest gain at the lowest frequency, more power is required here

than at the higher frequencies. Unlike other ampliers designed for general purpose applications, this

EMC specic amplier maximises the linear power at the lowest frequency, making it ideal for use in

this very specialised application.

The GaAs Class A design ensures a high reliability, low distortion linear performance across the frequency

range. This design also ensures that the amplier 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 amplier design for this frequency range and output power. Previous designs based on

silicon technology suffer from relatively poor compression characteristics, low efciency and sometimes

poor reliability.

The unit is powered from a switched mode power supply for high efciency, 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 amplier into standby mode. Front panel indicators are provided to indicate

over-temperature and rf interlock operation.
