Zida Zoyezera za Coaxial Precision 3-in-1 3.5mm N 2.92mm 2.4mm 1.85mm 7mm

Chida choyezera ma calibration ndi chida chofunikira kwambiri chowonetsetsa kuti vector network analyzer (VNA) ndi zida zina za RF zimapereka muyeso wolondola wa ndege yoyesera ya chipangizocho. Chifukwa cha kuwonjezeka kwa kusintha kwa gawo ndi impedance pakulumikizana kwa zida zoyesera za RF, kuyeza komwe kumachitika kudzera mu VNA popanda calibration kudzaphatikizapo magawo a S ndi mawonekedwe a nthawi ya dongosolo loyesera ma interconnection. Chida choyezera ma accuracy chimagwiritsidwa ntchito kupereka ndege yowunikira kuyambira pa kulumikizana kwa DUT. Mwanjira imeneyi, zida zoyezera za RF (makamaka VNA) zimatha kuchita zokha ntchito zovuta zolumikizira popanda kufunikira kukonza deta yowonjezera.

Gawo la maginito afupiafupi la zida zoyezera za 3.5mm limagwiritsidwa ntchito "kuchepetsa maginito" mphamvu yopangidwa ndi kutulutsa ndi VNA, pomwe gawo la maginito otseguka ndi kumapeto kwa mzere wotumizira womwe sungathe kutsekedwa womwe sumalola kulumikizana ndi kuwala kuchokera ku chilengedwe chakunja.

Katundu wa N calibration kit amagwiritsidwa ntchito kuti agwirizane ndi transmission line impedance ndi port impedance ya VNA ndi zida zoyesedwa.

Adapta yolunjika ndi adaputala yosavuta yomwe imalumikiza madoko awiri a zida zoyezera za 2.92mm, ndipo sizikuwoneka chifukwa cha cholinga chake chopanga kukhala pafupi ndi mzere woyenera wa magiya. Zida zoyezera za 2.4mm zimaphatikizapo zolumikizira zosiyanasiyana za coaxial zamitundu yosiyanasiyana, ndipo zodziwika kwambiri ndi cholumikizira cha mtundu wa N.

Chifukwa cha mitundu yosiyanasiyana ya zida zoyesedwa ndi zingwe za coaxial, zida zosinthira zolondola ndizofunikira kwambiri pa zida zoyezera. Pa zida zosinthira izi, ziyenera kukhala zapamwamba kwambiri.
