Yaya za a zaɓi abubuwan kabilo?

Ƙaramin kable na RF microwave sun kasu ne na tsari na samar da tansmisshon mai tsauri na signarolin da suka yi, kuma alama-alamansu na yayin daban sun haɗa da wadannan alamar na musa:

1.Alamun aikin elektrik

lLow loss and high bandwidth

Amfani da layer na foamed polyethylene insulation (wanda ke da dielectric constant kusan 1.3) kuma ma design na conductor na gaba (misali copper-clad aluminum ko solid copper) ya kama da skin effect losses kuma ya tura applications na wideband wanda tana kover DC-67GHz. Zaidan Insertion loss zai iya karewa ta hanyar calibration, amma design na low loss yake gaskiya a maimakon alhakin energy efficiency na system.

iyalin signal

(1)Standing Wave Ratio (VSWR): Components mai kwaliti mai yawa ke da VSWR daga 1 (misali ≤1.25:1), idan signal reflection loss zai kasa da 0.08dB, wanda zai kama da bit error rate a cikin multi carrier scenarios.

(2)Stability na phase: Semi rigid cables ke amfani da solid polytetrafluoroethylene medium, wanda ke da phase change mai yawa a kafin temperature; cables na flexible ana design su ne da armor kuma ma structures na kewayawa, kuma phase change a lokacin bending zai iya kara 5°.

intermodulation na passive (PIM)

Kabilon da na iya ƙima/na iya zukawa da ba su da alamu mai kyau (<-120dB) kuma suka wuya don samanin masani kamar yankan jihar farkawa.

2, Tsarin da Jikiyar Tsari

1. Matsayin tsayawa

Kabilon test na iya zukawa zai muta da matsayin tsayawa na jiki/na amfani: yawan ƙawayin a cikin ƙima zai muta ≤0.1dB, yawan canji na idan zai muta guda, kuma zai nuna kuskure na lissafi. Misali, yawan ƙawwayar da ke cikin 6GHz zai muta kuskuren lissafi na aiki.

2. Taimakewa da karkara

①Yana da yawan shekara da ke cikin 500 insertion da removal, VSWR ya tsara ≤1.3:1;

②Yana amfani da shell na alloy da takaici na taka (aluminum foil + copper wire weaving, takaici na taka ≥90dB), kuma zai taimake tsakanin -55℃~+265℃ da 15g na vibration acceleration, wanda zai yi nasarar cikin harshen da ke cikin jangali da jini.

Ƙaramin kable da mu ƙirƙira da ke da karamin tattara na ƙarƙata, na wave na karamin sirri, na loss na karamin sirri, mai tafiya, mai taka, da karamin yawan shekara. Suna da aminciyar iya canzawa su kuma an kara lafiya wajen so bin.
