Book excerpt: Efforts to determine the feasibility of constructing 10 mw 10 kmc tunnel diode oscillators continued and diode requirements for these oscillators were determined. Various materials, doping elements, and fabrication techniques were investigated to determine the best combination of these to potentially meet the frequency and power requirements. Three packaged and two distributed junction tunnel diode oscillators were designed and built. Using the packaged single diode oscillator, power outputs of 100 microwatts as been obtained in X- band and approximately 1/2 milliwatt at 5 - 6 kmc. Tuning problems held back use of larger capacity, larger peak current diodes which have cutoff frequencies well in excess of 10 kmc. Some circuit changes have been made to eliminate these tuning problems. Using a ring distributed tunnel diode in the distributed oscillator power outputs of 3 mw have been obtained at low frequencies. In addition, a stripline package oscillator is being built. The low impedance of this system should eliminate some of the impedance matching problems with the waveguide oscillators.

Book excerpt: Efforts to determine the feasibility of constructing 10 mw 10 kmc tunnel diode oscillators have continued and diode requirements for these oscillators determined. Various diode fabrication techniques and oscillator circuit techniques were investigated to determine the best combinations of these to potentially meet the frequency and power requirements. Four packaged and two distributed junction tunnel diode oscillators were designed and built. The present oscillator study has concentrated on the packaged X-band oscillators. Using the packaged single diode oscillators, power outputs of more than 100 microwatts have been obtained in X-band. Tuning problems seriously hamper the use of larger peak current, larger capacity packaged diodes. Some circuit changes have been made which partially alleviate this problem. The use of a resistive shunt across the ceramic of the diode package has improved the high-frequency or power output characteristics of these oscillators. The reduced-size stripline package oscillator is the most successful. Low peak current to capacitance ratios have been a difficulty for the distributed tunnel diode; so far no power output has been obtained in X-band from a distributed tunnel diode oscillator.

This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of tunnel diodes for us as scillators capable of mW output at frequencies up to 3 kmc is described. Inestigations on the failure of gallium arsenide units were made with no conclusive result. Experiments with different types of alrt to reduce the junction capacitance in germanium tunnel diodes. A low inductance - low capacitance modified stripline package was developed. The operation of oscillators using high current tunnel diodes above their self resonant frequency is presented. General stability conditions of the tunnel (lumped and distributed) are discussed. Based on a non-linear analysis of a tunnel diode oscillator, the power generated by the diode, the power dissipated within the diode, and the power delivered to an external load are calculated as a function of frequency and loading conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The 11th International Symposium on Superconductivity was held November 16-19, 1998, in Fukuoka, Japan. Convened annually since 1988, the symposium covers the whole field of superconductivity from fundamental physics and chemistry to new applications. At the 11th Symposium, there was increased interest reported in the development of trial devices using bismuth wires and yttrium-based bulk materials. Among the presentations were those that clearly defined the development targets for next-generation yttrium-based wires and bulk materials and single-flux quantum (SFQ) circuits. Other popular topics were high-temperature superconductivity applications such as SQUIDs, microwave filters, and cryocooler-cooled magnets. With more than 600 participants from 18 countries, the symposium provided an excellent forum for exchanges of the most recent information in the field of superconductivity.
