I-Dual Junction Isolator
Isihlukanisi esisidibanisa kabini sisixhobo sokwenziwa esiqhele ukusetyenziswa kwi-microwave kunye nee-millimeter-wave frequency bands ukwahlula imiqondiso ebonisiweyo ukusuka ekupheleni kwe-eriyali.Iqulethwe kulwakhiwo lwee-isolator ezimbini.Ilahleko yofakelo kunye nokwahlukaniswa ngokuqhelekileyo kuphindwe kabini kunomntu omnye.Ukuba ukwahlukaniswa kwe-isolator enye yi-20dB, ukwahlukaniswa kwe-isolator edibeneyo kabini kunokuba ngu-40dB.Izibuko lokuma wave alitshintshi kakhulu.
Kwinkqubo, xa isignali yefrikhwensi kanomathotholo ihanjiswa ukusuka kwizibuko lokungenisa ukuya kwindawo yokuqala yokudityaniswa kweringi, ngenxa yokuba isiphelo esinye sesidibanisi seringi sixhotyiswe nge-resistor frequency radio, isiginali yayo inokudluliselwa kuphela kwisiphelo segalelo sesibini. umsesane wokuhlangana.Umdibaniso wesibini we-loop uyafana nowokuqala, kunye ne-RF resistors efakiweyo, umqondiso uya kudluliselwa kwi-port yokuphuma, kwaye ukwahlula kwayo kuya kuba sisimbuku sokwahlukaniswa kweendlela ezimbini ze-loop.Umqondiso obonakalisiweyo obuyayo kwizibuko lemveliso uya kufunxwa sisixhathisi seRF kumdibaniso weringi wesibini.Ngale ndlela, iqondo elikhulu lokuzihlukanisa phakathi kwegalelo kunye nemveliso yezibuko liphunyeziwe, ngokufanelekileyo ukunciphisa ukubonakaliswa kunye nokuphazamiseka kwinkqubo.
