We report the first epitaxially grown, double transit region Gunn diode oscillator. The prototype device was operated at its second harmonic of 77 GHz, giving an RF output power of 64 mW as compared with 54 mW from the corresponding single transit region device. Measurements of threshold and breakdown voltage and of RF power support the interpretation of coherent nucleation of Gunn domains in the two transit regions and the satisfactory operation of the device.
