Tunnel-Diode Microwave Oscillators

Several experimental tunnel-diode RF oscillators which operate at frequencies from 610 to 8350 Mc are described. Power outputs an order of magnitude greater than those previously reported in the literature were obtained: 10 mw at 610 Mc, 2 mw at 1600 Mc, 0.7 mw at 2800 Mc, 0.2 mw at 5500 Mc, and 0.01 mw at 7130 Mc. Problems relating to oscillation frequency, power output, and wave shape are treated analytically.
