- Unconditionally stable
- Three year warranty
The CBA1G-070 amplifier from Teseq covers frequency range from 10 MHz to 1 GHz with rated power of 70 watts. The amplifier is specially designed for radiated EMC testing where it provides continuous output in to the very poor match typically associated with broadband EMC antenna tested at lower frequency range. Since antennas typically exhibit their lowest gain at the lowest frequency, more power is required here than at the higher frequencies. Unlike other amplifiers designed for general purpose applications, this EMC specific amplifier maximizes the linear power at the lowest frequency, making it ideal for use in this very specialized application.
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.
The unit is powered from a switched mode power supply for high efficiency, high power factor. 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.
