2. Loj
Sab nraud txoj kab uas hla: kwv yees li 5.08 hli (0.200 nti).
Sab hauv txoj kab uas hla: kwv yees li 2.08 hli (0.082 nti).
3. Hlau txoj kab uas hla
Central conductor: 22 AWG.
Shielding txheej: woven tooj liab mesh nrog ib tug weaving ceev ntawm txog 95%.
2, Kev ua haujlwm hluav taws xob
1. Yam ntxwv impedance
50 ohms: Tus yam ntxwv impedance ntawm RG223 cable yog 50 ohms, haum rau feem ntau RF thiab video kis daim ntaub ntawv.
2. Attenuation
Tsawg attenuation: RG223 cable muaj tsawg attenuation nyob rau hauv ntau zaus. Piv txwv li, ntawm 100 MHz, lub attenuation yog hais txog 0.22 dB / m; Ntawm 1000 MHz, qhov attenuation yog kwv yees li 0.67 dB / m.
3. Insertion poob
Kev poob qis qis: RG223 cable muaj qhov tsis muaj qhov tsis zoo, uas pab tswj cov teeb liab kev ncaj ncees thiab kev sib kis tau zoo.
4. Voltage Standing Wave Ratio (VSWR)
Qhov voltage sawv yoj piv ntawm RG223 cable nrog qis VSWR feem ntau yog tsawg dua 1.2: 1, qhia nws qhov kev ua tau zoo sib xws.
5. Cov nyhuv shielding
High shielding nyhuv: Lub shielding txheej ntawm woven tooj liab mesh muab zoo electromagnetic cuam tshuam (EMI) thiab xov tooj cua zaus cuam tshuam (RFI) shielding nyhuv.
3, Environmental adaptability
1. Qhov kub thiab txias
Kev tsim qhov kub thiab txias: Qee cov RG223 cables feem ntau tuaj yeem ua haujlwm ib txwm nyob hauv qhov kub ntawm -40 ° C txog 85 ° C thiab tsim nyog rau ntau yam ib puag ncig.
2. Kev tiv thaiv qib
Kev tiv thaiv siab: Cov ntaub qhwv sab nrauv feem ntau yog ua los ntawm cov khoom siv PVC, uas muaj qee yam dej noo- pov thawj, plua plav, thiab hnav- cov khoom tiv taus.
3. Mechanical zog
Lub zog zoo txhua yam: Cov txheej tiv thaiv ntawm cov woven tooj liab mesh thiab cov tawv tawv sab nrauv ua rau RG223 cable muaj lub zog zoo thiab tsim nyog siv rau ntau qhov chaw.
4, Txoj kev xaiv
1. Ntsuam xyuas cov cai thov
Kev sib kis deb: Xaiv qhov ntev ntawm cable raws li qhov tseeb kis tau tus mob ntawm daim ntawv thov. RG223 cable yog tsim rau cov teeb liab kis tau tus mob nyob nruab nrab mus rau luv luv.
Ntau zaus: Xaiv cov kab tsim nyog raws li qhov ntau zaus ntawm lub teeb liab. RG223 cable yog tsim rau ntau zaus ntawm 100 MHz txog 1000 MHz.
Ib puag ncig tej yam kev mob: Xaiv cov cables tsim nyog raws li qhov kub thiab txias, av noo, thiab kev co hauv qhov chaw nruab. Piv txwv li, xaiv high -kub resistant cables rau qhov kub thiab txias ib puag ncig thiab waterproof cables rau qhov chaw ntub dej.
2. Xaiv lub connector tsim nyog
RG223 cables feem ntau siv BNC thiab SMA connectors kom ntseeg tau tias kev sib raug zoo nrog lub cuab yeej. Hauv cov ntawv thov uas xav tau ntau zaus thiab lub zog ntau dua, N- hom connectors tuaj yeem xaiv.
3. Tshawb xyuas hluav taws xob ua haujlwm
Impedance, attenuation, insertion poob, VSWR: Xaiv cov cables nrog kev ua tau zoo ntawm hluav taws xob los xyuas kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov teeb liab kis tau tus mob.
4. Xav txog ib puag ncig adaptability
Qhov kub thiab txias, qib kev tiv thaiv, txhua yam muaj zog: Xaiv cov kab hluav taws xob uas tuaj yeem ua haujlwm ruaj khov hauv qhov chaw ua haujlwm.
