Teseq (formerly the instrumentation division of Schaffner) have released a large range of RF broadband, power amplifiers covering frequencies to 6 GHz and with output powers to 1100 watts. The RF broadband, power amplifiers are available from Westek Electronics .

RF broadband, power amplifiers are suitable for EMC immunity/susceptibility testing including radiated and conducted interference testing protocol requirements for general, commercial, military and automotive applications.

Teseq amplifiers are all class A and are capable of operating safely into open and short circuits, with low distortion and linear performance. Teseq amplifiers offer a high degree of reliability.

Teseq amplifiers are available with a large number convenient frequency break points allowing optimisation at various power levels. A typical example is the Teseq CBA100M-110, 10 kHz to 110 MHz, class A, broadband amplifier. The unit is powered from a switched mode power supply for high efficiency, 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.

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 GaAs Class A design ensures a high reliability, low distortion linear performance across the frequency range.
