A Highly Stabilized K/sub a/-Band Gunn Oscillator (Correspondence)

The construction and experimental results of a highly stabilized K/sub a/-band Gunn oscillator are described. The frequency stability is 3x10/sup -5/ at 25 GHz over the temperature range from 0 to 50/spl deg/C. An output power of more than 20 mW has been obtained in the frequency range up to 30 GHz. The frequency-saturation effect is also described.
