T1 QUASI-OPTICAL MILLIMETER WAVE SOLID-STATE OSCILLATORS. PART 2: HIGH-STABLE OSCILLATORS AND APPLICATION JF Telecommunications and Radio Engineering JO TRE YR 2019 FD 2019-03-13 VO 78 IS 4 SP 341 OP 361 K1 Gunn diode K1 IMPATT diode K1 quasi-optical solid-state oscillator K1 frequency noise K1 frequency stability K1 second harmonic AB The results of the study and development of quasi-optical solid-state oscillators are: the level of frequency noise is not more than 115...120 dB/Hz; power of generation at the first harmonic is up to 130...150 mW at a frequency of 40-50 GHz; at the second harmonic – up to 10 mW at a frequency of 60...90 GHz; generation power is not less than 3 mW at a frequency of 150 GHz; long-term frequency instability is 3·10–8 at active temperature control ΔT ~ 0.1 °C. The paper analyzes the areas of application of solid-state quasi-optical oscillators: heterodynes in receiving devices, refractometry, dielectrometry and other fields where high stability and low level of frequency noise are needed. The perspective directions of the search for new physical phenomena to create nonlinear elements in the terahertz frequency range are determined.
