X-BAND TUBE-AND-CAVITY-COMBINATION OSCILLATOR.
Abstract
After a successful study of optimum triode integration into X-band circuitry and of high emission density oxide cathodes, triode oscillators for use at X-band (9.35-9.65 Gc) were designed, built and tested. Low over-all power drain (less than 5 watts) at a plate voltage of 150 V, light weight (less than 1 ounce), and simplicity of operation (single knob tuning) make them especially attractive when compared to more complicated existing devices. Since com ponents and assembly are compatible with established production techniques, the design could be refined to a very economical product in a minimum time. Successful 500-hour life performance has been demonstrated. Novel heatercathode techniques play a large part in making this performance possible. In addition, experimental triodes capable of generating 2 watts over the 9.3 to 9.6 Gc band have been demonstrated. Most of these have built-in resonators and adjustable grid-anode gaps that allow a CWoscillator plate efficiency of 5% at X-band. (Author)
