Kusiyana pakati pa ma RF isolators ndi ma RF circulators

Mu ntchito zothandiza, ma RF isolators ndi ma RF circulators nthawi zambiri amatchulidwa nthawi imodzi.
Kodi pali ubale wotani pakati pa ma RF isolators ndi ma RF circulators? Kodi pali kusiyana kotani?
Nkhaniyi ifotokoza kwambiri za nkhani zimenezi.
Cholekanitsa mafunde a wailesi, chomwe chimadziwikanso kuti chipangizo cholunjika mbali imodzi, ndi chipangizo chomwe chimatumiza mafunde amagetsi mbali imodzi. Mafunde amagetsi akafalikira mbali imodzi, amatha kupereka mphamvu zonse ku katunduyo ndikupangitsa kuti mafunde owonetsedwa achepetse kwambiri kuchokera ku katunduyo. Khalidwe lotumizira mbali imodzili lingagwiritsidwe ntchito kusiyanitsa momwe katundu amakhudzira gwero la chizindikiro.
Ma RF circulators ndi njira zotumizira nthambi zomwe sizigwirizana. Ma ferrite RF circulators omwe amagwiritsidwa ntchito kwambiri ndi ma Y-shaped RF circulators, omwe amapangidwa ndi mizere itatu ya nthambi yogawidwa mofanana pa ngodya ya 120 ° kwa wina ndi mnzake.

1,Kodi cholekanitsa cha RF n'chiyani?
Chopatulira mafunde a wailesi, chomwe chimadziwikanso kuti chipangizo chopatulira mbali imodzi, ndi chipangizo chomwe chimatumiza mafunde amagetsi mbali imodzi. Mafunde amagetsi akafalikira mbali imodzi, amatha kupatsa mphamvu zonse ku katunduyo ndikupangitsa kuti mafunde owonetsedwa achepe kwambiri kuchokera ku katunduyo. Khalidwe lopatulira mbali imodzili lingagwiritsidwe ntchito kupatula momwe kusintha kwa katundu kumakhudzira gwero la chizindikiro. Potengera chopatulira chosuntha chamunda mwachitsanzo, fotokozaninso mfundo yogwirira ntchito ya chopatulira cha ferrite RF.

Zolekanitsa magetsi za Field shift zimapangidwa kutengera zotsatira zosiyanasiyana za ferrite pa ma wave modes zomwe zimatumizidwa mbali ziwiri. Zimawonjezera ma attenuation plates kumbali ya ferrite sheet, ndipo chifukwa cha kusiyana kosiyana kwa minda komwe kumapangidwa ndi njira ziwiri zotumizira, mphamvu yamagetsi ya ma wave yomwe imatumizidwa kutsogolo (- z direction) imalunjika mbali yopanda ma attenuation plates, pomwe mphamvu yamagetsi ya ma wave yomwe imatumizidwa kumbuyo (+ z direction) imalunjika mbali ya ma attenuation plates, motero kukwaniritsa ntchito yodzipatula ya attenuation yaying'ono kutsogolo ndi attenuation yayikulu yakumbuyo, monga momwe zasonyezedwera pachithunzichi.2.

2,Kodi ma RF circulators ndi chiyani?
Ma RF circulators ndi njira zotumizira nthambi zomwe sizigwirizana. Ma ferrite RF circulators omwe amagwiritsidwa ntchito kwambiri ndi ma RF circulators ofanana ndi Y, monga momwe zasonyezedwera mu Chithunzi 3 (a), omwe amapangidwa 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 maginito mbali zonse ndi ofanana. Pamene chizindikiro chikulowetsedwa kuchokera ku mzere wa nthambi "①", mphamvu ya maginito monga momwe zasonyezedwera mu Chithunzi 3 (b) idzasangalatsidwa pa malo olumikizirana a ferrite. Chifukwa cha mikhalidwe yomweyi ya nthambi "②, ③", chizindikirocho chimatuluka m'magawo ofanana. Pamene mphamvu ya maginito yoyenera ikugwiritsidwa ntchito, ferrite imasangalatsidwa, ndipo chifukwa cha zotsatira za anisotropy, mphamvu ya maginito monga momwe zasonyezedwera mu Chithunzi 3 (c) imasangalatsidwa pa malo olumikizirana a ferrite. Pamene mphamvu ya maginito yoyenera ikugwiritsidwa ntchito, ferrite imapangidwa ndi maginito, ndipo chifukwa cha anisotropy, pamakhala chizindikiro chotulutsa pa nthambi "②", pomwe mphamvu yamagetsi pa nthambi "③" ndi zero ndipo palibe chizindikiro chotulutsa. Pamenenso cholowetsa kuchokera ku nthambi "②", nthambi "③" ili ndi chotulutsa, pomwe nthambi "①" ilibe chotulutsa; Pamene cholowetsa kuchokera ku nthambi "③", nthambi "①" ili ndi chotulutsa pomwe nthambi "②" ilibe chotulutsa. Zitha kuwoneka kuti imapanga kuzungulira kwa unidirectional kwa "①" → "②" → "③" → "①", ndipo njira yobwerera siilumikizidwa, kotero imatchedwa RF circulator.
