CBa 4 00M-110

10 kHz to 400 MHz 110 Wat t Class a BroadBand aMplifier

Designed specically for automotive, military and aerospace BCI and other susceptibility EMC testing, this mismatch tolerant Class A amplier 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 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 technolog y rep -

resents a breakthrough in amplier design for this frequency range and output power. Previous designs based on silicon technolog y 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.

Notes:

1. The third order intercept point is a nominal value, as its calculation depends upon the power level at which distortion measurements are made.

2. Output VSWR tolerance is specied for excitation within the permitted levels and frequency range.
