Teseq (formerly the instrumentation division of Schaffner) has released a 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.
The devices are available with a number of frequency break points allowing optimisation at various power levels.
One example is the CBA100M-110, 10 kHz to 110 MHz, class A, broadband amplifier.
The unit is powered from a switched mode power supply with a 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 operation.
The CBA 3G-025 800 MHz to 3.1 GHz, 25 W device is designed specifically for radiated EMC testing because of its ability to continuously supply RF power into the poor and variable matched loads typically associated with testing above 1 GHz through increasing cable losses at the higher frequencies.
