Ukubaluleka Kokuqedwa Kokungalingani Kwe-Coaxial ku-RF kanye nobunjiniyela be-Microwave

Ukuphela kokungafani kwe-coaxial kuyisici esibalulekile emkhakheni we-RF kanye nobunjiniyela be-microwave. Kusetshenziselwa ukumunca isignali eboniswa emuva kusukela ekungahambelani kwe-impedance emgqeni wokudlulisela. Kalula nje, lapho kukhona ukungafani phakathi kwe-impedance ephawulekayo yomugqa wokudlulisela kanye ne-impedance yomthwalo, ingxenye yesignali iboniswa emuva ibheke emthonjeni. Lesi signali esibonakalayo singabangela ukuphambuka kwesignali, ukulahlekelwa amandla, kanye nezinye izinkinga ohlelweni.

Ukuphela kokungalingani kwe-coaxial kuklanyelwe ukumunca lesi signali esibonisiwe futhi kunciphise umthelela waso ohlelweni. Ngokuyisisekelo kunikeza ukuphela okufanelana nomugqa wokudlulisela, okuqinisekisa ukuthi yonke isignali imuncwa kahle futhi akukho ukubonakaliswa okwenzekayo. Lokhu kusiza ukugcina ubuqotho besignali kanye nokusebenza kahle kohlelo.

Kunezinhlobo ezahlukene zokuphela kwe-coaxial mismatch ezitholakalayo, kufaka phakathi ukuphela kwe-resistive, ukuphela kwe-reactive, kanye nokuphela kwe-complex impedance. Uhlobo ngalunye lunezinzuzo zalo kanye nezinhlelo zokusebenza, kuye ngezidingo ezithile zesistimu.

Ekuphetheni, ukuphela kokungalingani kwe-coaxial kuyisici esibalulekile ezinhlelweni ze-RF kanye ne-microwave ukuqinisekisa ubuqotho besignali kanye nokusebenza kahle. Ngokumunca kahle isignali eboniswayo evela ekungahambelani kwe-impedance, kusiza ukuthuthukisa ukusebenza kwesistimu nokuvimbela ukuphambuka kwesignali.
