Kutsetsereka Kofanana ndi Kutha kwa RF Microwave High Frequency Radio Loads

Kutha kwa RF ndi mtundu wa gawo lolondola la kuwerengera kwa ma analyzer a vector network, lomwe limapangidwa makamaka ndi mizere ya mpweya ndi cylindrical ferrite mkati.

Kuletsa kwapadera kwa chingwe cha mpweya kumatsimikiziridwa ndi kukula kwa kondakitala wamkati ndi kukula kwamkati kwa kondakitala wakunja. Kuletsa kwachizolowezi kumakhala ndi kondakitala wake wamkati wolumikizidwa ndi chinthu chokhala ndi chophimba chotsutsa, ndipo pali mabowo owongolera pakati pa chophimbacho kuti chiwongolere kuchuluka kwa kuletsa kwa kufananiza kwa kuletsa. Mzere wa mpweya wa kutsirizitsa kwa microwave umapangitsa kuti kuletsa kwake kwapadera kukhale kolondola kwambiri kuposa kuthetseratu kwachizolowezi.

Ndodo zamaginito za Ferrite zimatha kuyamwa mphamvu zambiri zamaginito. Tikayendetsa maginito a ferrite panthawi yowunikira, kutalika kwa offset, coefficient yowunikira, ndi gawo la mzere wa mpweya zonse zimasintha.

Mwa kutsetsereka kwa ndodo ya ferrite magnetic, impedance ndi return loss zitha kukonzedwa kuti zitsimikizire kulondola kwa calibration mu high frequency range. Mwa kusuntha malo a terminal kuti musinthe gawo la reflection la terminal reflection coefficient, Radio frequency loads imatha kuzindikira cholakwika choyesera cha terminal mu system kapena muyeso, ndipo imagwiritsidwa ntchito kwambiri poyesa molondola ma vector network analyzers. Chifukwa cha kuthekera kwake kosintha molondola kwa characteristic impedance, sliding terminals imagwira ntchito bwino mu high-frequency applications.
