THE DESIGN AND DEVELOPMENT OF A FIVE WATT NUVISTOR TRIODE.
Abstract
The report covers the design and development of two nuvistor triodes having a plate dissipation capability of 5-6 watts. The two developmental types are identical in electrical characteristics but differ in envelope and terminal construction. One version, the A15512A, has a coaxial cathode terminal and the other, the A15526, has a leaded base similar to conventional nuvistors. Both types are designed for application on pulsed or cw Class C amplifiers, oscillators, or frequency multipliers at frequencies up to 1.2 Gc/s. Power output of a cw amplifier at 1.2 Gc/s with a plate input of 10 watts is about 4.4 watts. Under pulsed amplifier operation at 1.0 Gc/s, 0.025 duty factor, 5 micro sec. pulse duration, and 4.8 watts average plate input power, the peak output power is about 105 watts. Both types have an amplification factor of 100 and a transconductance of 19,000 micro mhos at a plate voltage of 200 volts, a plate current of 15.5 ma., and a cathode resistance of 68 ohms. It is believed that both types, the A15512A and the A15526, have met the objective specifications of the contract. (Author)
