Broadband, RF power amplifiers for EMC applications from Teseq, and available from Westek Electronics

Supplier News

Teseq (formerly the instrumentation division of Schaffner) makes available a range of RF broadband, power amplifiers covering frequencies to 6 GHz and with output powers to 1100 watts, suitable for EMC immunity/susceptibility testing. This includes radiated and conducted interference testing protocol requirements for general, commercial, military and automotive applications.

The Teseq amplifiers are capable of operating into open and short circuits, with low distortion and linear performance. They have a three-year warranty period. Teseq amplifiers are available with a large number convenient frequency break points allowing optimization at various power levels. A typical example is the Teseq CBA100M-110, 10 kHz to 110 MHz broadband amplifier.

The unit is powered from a switched mode power supply to increase efficiency, 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. Another example of Teseq engineering is the CBA 3G-025 800 MHz to 3.1 GHz, 25 watt amplifier, 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.

 The Teseq power amplifiers are made available by Westek Electronics .
