DISTRIBUTED JUNCTION TUNNEL DIODE OSCILLATOR. PHASE 2
Abstract
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.
