High Performance Fixed IMPATT Oscillators 26-180 GHz

Features
 
  • High power output levels
  • Ultra Low phase and AM noise
Applications
  • Power sources
  • Spectroscopy/Radiometry
  • Digital Radio
Description  

     Complete High performance fixed IMPATT oscillators are very stable solid state millimeter wave source with ultra low phase AM noise. Oscillator consists of transistor oscillator stabilized by the dielectric resonator (DRO) 6-8 GHz, 50 mW output, 10-6 frequency stability. The stability would be increased upon request using a temperature stabilization scheme.

See on picture, at 10 kHz offset, the difference in power between carrier and 10kHz offset marker is –69.6dBc. Taking into account that bandwidth is 1kHz , the spectrum density of noise is –99.6dBc/Hz. Assuming that we have two equivalent sources the noise power of each source is 3 dB less, i.e. –102.6 dBc/Hz
