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.

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.

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.

Download or read book Tunnelling and Negative Resistance Phenomena in Semiconductors written by D. K. Roy and published by Elsevier. This book was released on 2014-05-09 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tunnelling and Negative Resistance Phenomena in Semiconductors presents a critical review of tunneling theory and shows how this leads to the negative resistance phenomena in pn junctions. The physics, technology, and circuitry of semiconductor negative resistance devices are surveyed. The book challenges the conventional assumptions of tunneling theory and proposes an alternative approach that allows the possibility of a change in energy during tunneling. It also introduces the reader to the manufacture, operation, and applications of semiconductor negative resistance devices. Comprised of five chapters, this volume begins by presenting a logical physical interpretation of the wavefunction with its so-called ill-behaved nature and considering other consequences of the energy distribution effect. The next chapter is devoted to the tunneling effect through tunnel diodes along with other properties of this device. The circuitry and technology of tunnel diodes as well as backward and Zener diodes are then examined, along with negative conductance devices that are used as microwave sources. The final chapter is concerned with negative conductance switching devices. This book is intended for students and practitioners in the fields of physics and electronics.
