Popis:	The use of microwave energy for industrial processing applications has been ongoing since the early 1950's. A number of high power tubes were developed in the mid-1960's at 805, 915 and 2,450 MHz for industrial uses. One super power crossed-field amplifier (CFA), the QKS1262, was available in either 50 or 100 kW continuous wave (CW) format. This CFA was designed with a platinum emitter which was pulse started with 100 W average power. The CFA operates at ∼20 kV at 5 amps (50 kW - CW output) or 10 amps (100 kW - CW output/65% efficiency).This paper will describe the operating characteristics of the QKS1262 and the options in design to attain high power with high efficiency and long life (25,000 hours).
