MICROWAVE HEATING DEVICE Russian patent published in 1995 - IPC

FIELD: microwave devices. SUBSTANCE: device has solid-state microwave source, which is designed as self-excited oscillator, unit for regulation of power and mode of self-excited oscillator, circulator, transmitter. Transistor of self-excited oscillator is designed as transistor crystals, which are connected in parallel and divided to sections, which are connected to one another by circuits for suppression of noise lateral oscillations. Electric size of each section in direction that is perpendicular to microwave power transfer is less than half of oscillations wavelength of working frequency. EFFECT: increased functional capabilities. 4 cl, 4 dwg
