Teseq (formerly the instrumentation division of Schaffner) has released a large range of RF broadband power amplifiers covering frequencies to 6 GHz and with outputs to 1100 W.
They are suitable for EMC immunity/susceptibility testing including radiated and conducted interference testing protocol requirements for general, commercial, military and motor vehicle applications.
The amplifiers are all class A and can operate safely into open and short circuits, with low distortion and linear performance.
They represent a high degree of reliability and are available with a large number of frequency break points, allowing optimisation at various power levels.
A typical example is the CBA100M-110, 10 kHz to 110 MHz. The unit is powered from a switched-mode supply and is air-cooled with integral fans and 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. Another unit in the range is the CBA 3G-025 800 MHz to 3.1 GHz, 25 W, designed specifically for radiated EMC testing because of its ability to continuously supply RF power into the poor and variable matched loads at testing above 1 GHz.
