Chaza ngokufutshane iiparameters zentsebenzo ye-RF isolators

Kwiinkqubo zeRF, owona msebenzi uphambili weI-RF isolatorskukubonelela okanye ukwandisa ubunakho bokwahlula kwiindlela zophawu ezahlukeneyo. Yinkqubo ephuculweyo ejikelezayo epheliswe ngokudibana kokuphazamiseka kwelinye lamazibuko ayo. Ngokuqhelekileyo isetyenziselwa kwiinkqubo ze-radar ukukhusela iisekethe ezithintekayo ekupheleni kokufumana ukuphepha ukuphazamiseka kwiimpawu ezigqithisiweyo zamandla aphezulu, ngaloo ndlela ukuphumeza ukuhlukaniswa okusebenzayo kwezibonakaliso ezidlulisiweyo kunye nezifunyenweyo. Eli nqaku liza kukuthatha ukuba uqonde iiparamitha zokusebenza eziphambili zeI-RF isolators.

一. Ingcaciso
I-RF isolatorsluhlobo olukhethekileyo lweabajikelezi be-RF, apho izibuko elinye (ngokuqhelekileyo isiphelo sendlela ebuyela umva yekhonkco lomqondiso) inqanyulwe ngumthwalo ohambelanayo ukuphumeza ukuhanjiswa kwemiqondiso ngokungafaniyo. Ivumela kuphela imiqondiso ukuba idlule kwicala elimiselweyo ngelixa icinezela imbonakalo, ingxolo okanye imiqondiso yokuphazamiseka ukusuka kwicala elingasemva, ngaloo ndlela ifezekisa ukwahlukaniswa okusebenzayo kwekhonkco langaphambili.

I-RF isolators or abajikelezayozidla ngokuba zizixhobo ze-ferrite ezingenzi nto ezikhokela amaza ombane ukusuka kwisiphelo sogalelo kwicala elithile ngolungelelwaniso lwendawo ethile yemagnethi kunye nemveliso kwizibuko elikufutshane.

Xa kuthelekiswa nezahlulo zodwa ezilungisiweyo ukusuka kwisiqheloabajikelezi be-RF, izixhobo ezenzelwe ngokukodwa iinjongo zokuzihlukanisa zihlala zihlangene kwaye kulula ukuzidibanisa. Ukusebenza kwayo yodwa kuchaphazeleka ngokuthe ngqo kumgangatho wokulinganisa i-terminal.

I-high frequency standard isolator, Isolation (12-14dB), 18 ukuya kwi-40GHz

二. Iiparamitha zokusebenza
Iimpawu eziphambili zokusebenza zeI-RF isolatorsziquka:

Uluhlu lokuphindaphinda (Hz)

Ukuphazamiseka (Ω)

Ilahleko yokufaka (dB)

Ukwahlukaniswa (dB)

Umlinganiselo wamaza ombane omileyo (VSWR)

Phambili amandla okuphatha amandla (amaza aqhubekayo okanye incopho)

Ukubuyisela umva amandla okuphatha amandla (amaza aqhubekayo okanye incopho)

Uhlobo lwesidibanisi

Phakathi kwazo, ukwahlukana yenye yezona parameters zibaluleke kakhulu, ezibonisa iqondo lokudibanisa phakathi kweendlela zeRF kwiidecibels (dB). Ixabiso eliphezulu, elincinci ukudibanisa phakathi kwemiqondiso kwaye ngcono umphumo wokuzihlukanisa. Kuba ukudityaniswa kwe-electromagnetic kuxhaphakile kuzo zonke iindlela zokuqhuba, kubaluleke kakhulu ukugcina ukwahlukaniswa okuphezulu phakathi kweendlela zonxibelelwano oluchanekileyo okanye iinkqubo zokuva.

Ukongeza, ngokweemfuno ezahlukeneyo zesicelo,abantu ababodwakufuneka kwakhona ibe nomthamo ofanelekileyo wokuphatha amandla, i-VSWR ephantsi, ulwakhiwo lwesiqhagamshelo esithembeke kakhulu, ubungakanani obufanelekileyo, kunye noluhlu lobushushu obuguquguqukayo bokusebenza, obunokuchaphazela ukusebenza kwabo kwiimeko zokwenyani. Isalathiso samandla esiphezulu se-isolator sinokunqunyulwa kwakhona ngeempawu zomthwalo oyekiweyo.
