  • Abstract
    The Avalanche or Gunn diode oscillators in simple single resonator circuits usually have considerably more FM noise then Klystron or crystal-oscillator, multiplier-chain type signal sources. Transmission cavity stabilization by TE/sub oln/ mode cavities is applied to both Avalanche and Gunn diode X-Band oscillators to yield simple, useful signal sources with FM noise lower than most other signal sources. Some additional studies show that a cavity stabilized silicon avalanche diode oscillator used as a synchronizing signal to injection phase lock a Gunn oscillator has the best combination of low FM and AM noise.
