RF Dummy Load ndi chipangizo chomwe chimagwiritsidwa ntchito kuyerekezera kuchuluka kwamagetsi pakuyesa. Ikhoza kuyesa zida zanu za RF popanda kusokoneza mafunde a wailesi.

Kaya ndinu odziwa zambiri pankhani ya RF kapena ayi, mudzafunika RF dummy load kuti muyese zida za RF kuti mutsimikizire kuti wayilesi ikugwira ntchito moyenera. Koma kodi mukudziwa momwe mungazindikire katundu wabwino kwambiri wa RF mukamakumana ndi zisankho zosiyanasiyana pamsika?

Kuti tikuthandizeni kugula katundu wabwino komanso wotsika mtengo wa RF dummy, tikuwonetsa mfundo 6 zofunika kuziganizira. Tiyeni tiyambe!

1 # Mulingo wa Mphamvu

Mukayesa zida za RF, mupeza kuti RF dummy load ikuyenda mosalekeza. Kuti mugwire ntchito motetezeka, muyenera kuyang'ana ngati mphamvu yamagetsi ikukhutitsidwa ndi zosowa zanu osati mphamvu yapamwamba.

Nthawi zambiri, tikulimbikitsidwa kuti mphamvu yotsika ya RF dummy load (pansi pa 200w) ikhale yamawayilesi osaphunzira komanso mawayilesi amagetsi ochepa pomwe mphamvu yayikulu ya RF dummy load ndi yama wayilesi akatswiri.

2 # Mafupipafupi osiyanasiyana

Muyenera kudziwa ngati ma frequency osiyanasiyana amakwaniritsa zosowa zanu. Nthawi zambiri, RF dummy load imakhala ndi gulu lafupipafupi ngati DC (ndiye 0) mpaka 2GHz, kotero simuyenera kudandaula nazo kwambiri. 

3 # Makhalidwe Osokoneza

Mofanana ndi makina a antenna, katundu wa RF dummy ayenera kukhala wofanana bwino ndi magwero a RF. Chifukwa chake, mtengo wa dummy load impedance uyenera kukhala wofanana ndi mlongoti kapena chingwe chotumizira.

The RF dummy load 50 Ohm ndi 75 Ohm ndi mitundu yomwe timagwiritsa ntchito. Ndipo RF dummy load 50 Ohm nthawi zambiri imagwirizana ndi magwero a RF bwino muzochitika za RF.

4 # Njira Yowonongera Kutentha

Cholinga cha RF dummy load ndikulowetsa mlongoti ndi kulandira mphamvu ya RF. Mphamvu zowonongeka zidzasandulika kutentha mu katundu wa dummy, choncho, muyenera kulabadira dongosolo la kutentha kwa kutentha.

Nthawi zambiri, dummy katundu amadalira heatsinks, ndipo amapangidwa kuchokera aloyi, aluminiyamu, etc., ndipo mtundu uwu wa dummy katundu amatchedwa dry heatsink load. Kupatula dongosolo lotayira pamwambapa, pali zonyamula zina za RF zomwe zimataya kutentha ndi madzi, kuphatikiza madzi, mafuta ndi mpweya, ndi zina. 

Malinga ndi injiniya wathu Jimmy, kuziziritsa madzi ndi njira yabwino kwambiri yochotsera kutentha koma kumafuna kukonza movutikira.

5 # Mitundu Yolumikizira

Kulumikiza magwero a RF ndi RF dummy load ndiye gawo lomaliza pokonzekera. Zomwe muyenera kuchita ndikuwonetsetsa kuti cholumikizira chikugwirizana. 

The RF dummy load ili ndi mitundu yosiyanasiyana yolumikizira mitundu, kuphatikiza mtundu wa N, mtundu wa BNC, ndi zina zambiri.

Kutsiliza

Ponena za izi, mwakhala ndi chidziwitso chonyamula katundu wabwino kwambiri wa RF dummy. Katundu wabwino wa RF dummy nthawi zambiri ndiwofunikira pakumanga wayilesi. 

Ngati mukufuna thandizo lochulukirapo pomanga wayilesi yanu, bwanji osapeza mtundu wodalirika kuti akuthandizeni? Mwachitsanzo, FMUSER sangakupatseni katundu wa RF dummy wokhala ndi mphamvu zambiri kuyambira 1W mpaka 20KW, okhala ndi mitundu yosiyanasiyana ya zolumikizira ndi njira zochotsera kutentha zomwe zimakwaniritsa zosowa zanu zosiyanasiyana.

Ngati mukufuna zambiri za RF dummy load, chonde omasuka kulankhula nafe!
