Kodi RF Circulator ndi chiyani ndipo RF isolator ndi chiyani?
Kodi RF Circulator ndi chiyani?
RF circulator ndi njira yotumizira ma branch yokhala ndi makhalidwe osagwirizana. Ferrite RF circulator imapangidwa ndi kapangidwe ka pakati kooneka ngati Y, monga momwe chithunzichi chikusonyezera. Imapangidwa ndi mizere itatu ya nthambi yogawidwa mofanana pa ngodya ya 120 ° kwa wina ndi mnzake. Pamene mphamvu ya maginito yakunja ili zero, ferrite simakhala ndi maginito, kotero mphamvu ya maginito mbali zonse imakhala yofanana. Pamene chizindikiro chikulowetsedwa kuchokera ku terminal 1, mphamvu ya maginito monga momwe zasonyezedwera mu chithunzi cha magnetic characteristic diagram idzasangalatsidwa pa malo olumikizirana ma ferrite, ndipo chizindikirocho chidzatumizidwa ku zotuluka kuchokera ku terminal 2. Mofananamo, chizindikiro cholowera kuchokera ku terminal 2 chidzatumizidwa ku terminal 3, ndipo chizindikiro cholowera kuchokera ku terminal 3 chidzatumizidwa ku terminal 1. Chifukwa cha ntchito yake ya chizindikiro choyendera ma cycle, chimatchedwa RF circulator.
Kugwiritsa ntchito kwachizolowezi kwa circulator: antenna yodziwika bwino yotumizira ndi kulandira zizindikiro
Kodi RF isolator ndi chiyani?
Cholekanitsa cha RF, chomwe chimadziwikanso kuti chipangizo cholunjika chimodzi, ndi chipangizo chomwe chimatumiza mafunde amagetsi m'njira imodzi. Pamene mafunde amagetsi atumizidwa kutsogolo, amatha kupereka mphamvu zonse ku antenna, zomwe zimapangitsa kuti mafunde owonetsedwa kuchokera ku antenna achepe kwambiri. Khalidwe logawa mafunde m'njira imodzi lingagwiritsidwe ntchito kusiyanitsa momwe kusintha kwa ma antenna kumakhudzira gwero la chizindikiro. Mwanjira ina, kulumikiza katundu ku doko lililonse la circulator kumatchedwa cholekanitsa.
Zodzipatula nthawi zambiri zimagwiritsidwa ntchito poteteza zipangizo. Mu ma amplifiers amphamvu a RF omwe ali m'munda wolumikizirana, amateteza makamaka chubu cha amplifier yamagetsi ndipo amaikidwa kumapeto kwa chubu cha amplifier yamagetsi.
