Designed specifically for Radiated EMC testing, the CBA6G-030 mismatch tolerant amplifier delivers power continuously into the poor and variable match typically associated with testing above 1 GHz. Although antenna are usually well matched at these high frequencies, the presence of the EUT in the path of the antenna causes high levels of reflected power which the high breakdown voltage of GaN (Gallium Nitride) can handle with ease.
Although antenna gain is relatively constant, increasing cable losses at the higher frequencies demand increasing power with increasing frequency. Teseq amplifiers are therefore designed to maintain their high linear output power right up to and beyond the defined frequency range. The GaN balanced pair design at the core of the amplifier 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 effi 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 amplifier into standby mode. Front panel indicators are provided to indicate over-temperature and rf interlock condition.
