De hoofd functie van hybride koppelaar is aan de magnetron vermogen van één kanaal in meerdere kanalen volgens aan verhouding in de magnetron systeem, voornamelijk aan realiseren vermogen distributie. hybride koppelaar can be gecombineerd met andere componenten aan vorm schakelen schakeling, logica circuit, geïsoleerd koppeling circuit, hoog spanning regelaar circuit, hall licht automatisch besturing circuit, etc.
In magnetron systeem, it is vaak noodzakelijk om de magnetron power van één kanaal in meerdere kanalen proportioneel, which is the power distribution problem. The component to realize this function is called hybrid coupler, which mainly includes directional hybrid coupler, power distributor and various microwave branch devices.
Inleiding aan hybride koppeling
hybrid coupler is a common power distribution component. It is an electric-opto-electric conversion device that transmits electrical signals through optical medium. The light source and light receiver are assembled in the same closed shell and separated by transparent insulators. The pin of the light source is the input end, the pin of the light receiver is the output end, the common light source is the light emitting diode, the light receiver is the photosensitive diode, photosensitive transistor and so on.
Fotodiode, which is actually a photoresistor, is very sensitive to changes in light. The core of photodiode is a PN junction with photosensitive characteristics, which has unidirectional conductivity, so it can use the intensity of light to change the current in the circuit. Photosensitive transistor is essentially a kind of ordinary triode equivalent to a photosensitive diode in the base and collector. Lichtgevoelig triodes zijn gebruikt om meten helderheid en zijn vaak gebruikt in conjunctie met licht-zendend diodes als signaal ontvangen apparaten.
Magnetron introductie
Microwave refers to the frequency of 300MHz to 300GHz electromagnetic wave, is a limited frequency band of radio waves for short, namely wavelength in 1 meter (excluding 1 meter) to 1 mm electromagnetic wave, is decimeter wave, centimeter wave, millimeter wave and submillimeter wave collectively.
