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 use of gallium arsenide technology rep-
resents a breakthrough in amplifier design for this frequency range and output power. Previous designs
based on silicon technology suffer from relatively poor compression characteristics, low efficiency and
sometimes poor reliability.
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.
