Autodyne Effect in Microwave Oscillators with Injection Locking

Journal of Communications Technology and Electronics, 2020
Specific features of the autodyne response in oscillators in the presence of simultaneous intrinsic reflected radiation and external locking are studied. Main expressions for analysis of the autodyne response under conditions for quasi-static slow and fast motion of a radar object are obtained for the scenario in which the signal period is comparable ...

An analysis of the autodyne effect of oscillators with linear frequency modulation

Russian Physics Journal, 2008
General equations are obtained for the autodyne response in the case of an arbitrary frequency modulation both over the active element bias circuit and voltage variation on the voltage-dependent capacitor (varicap). The results of investigation of an autodyne oscillator with linear frequency modulation following the antisymmetric and symmetric saw ...

Application of Frequency Locking and Control to an Autodyne Oscillating NMR Detector

Review of Scientific Instruments, 1970
The use of an autodyne oscillating NMR detector is discussed with particular reference to experimental situations where signal averaging or magnet field locking are involved. A frequency locking scheme which has proved very useful in this connection is described.

Temperature feature analysis of autodyne oscillators on gunn diode

2008 18th International Crimean Conference - Microwave & Telecommunication Technology, 2008
Theoretical analysis fulfilled for temperature impact upon autodyne oscillators shows that this factor causes the self-oscillation condition changing first of all: namely, auto-bias, amplitude and frequency of oscillations, as well as output power. Temperature curves of the autodyne potential, its output levels of the signal and noise are determined by
