| 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. | |

Typical performance for W-band solution.
Scheme of measurement.
See on picture, at 10 kHz offset, the difference in power between carrier and 10 kHz offset marker is –69.6 dBc. Taking into account that bandwidth is 1 kHz , 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
