Overview
The Schaffner CBA 9479 is now known as the Teseq CBA 1G-018 amplifier.
Designed specifically for EMC testing, this mismatch tolerant Class A amplifier is able to produce a test field of 10 V/m in GTEM cells up to 1 m in height and can also produce more than a 10 V test level when used in conjunction with a CDN. This amplifier is ideal for a small test facility as it conveniently covers both the conducted and radiated bands of the IEC 61000-4 standard.
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 re-presents 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.
