TWTA Eases Automotive EMC Testing

March 4, 2004

Automotive electronic systems must be rugged designed not only to withstand wide temperature extremes, but also to handle the high field strengths emitted by speed radar pulses. To test automotive electronics, Amplifier Research (Souderton, PA) developed a dual-band traveling-wave-tube amplifier (TWTA) capable of generating the pulsed output-power requirements according to both Ford and General Motors' specifications. The tube amplifier (model 1000TP1G3), which can deliver 600-V/m pulses in two discrete bands of 1.15 to 1.45 GHz and 2.7 to 3.1 GHz, replaces two separate tube amplifiers with output power levels of 1000 and 500 W, respectively, in the two frequency bands.
