Yuav ua li cas SMA-J Connectors ntsib siab- zaus xeem yuav tsum tau muaj?

Hauv siab -frequency signal kis rau cov khoom siv hluav taws xob, kev ua haujlwm txuas ncaj qha cuam tshuam rau cov teeb liab ruaj khov thiab kev ntseeg tau ntawm cov cuab yeej. Tsim los rau SS402, CXN3449, thiab 210A cables, no SMA-J (txiv neej) connector yog ib qho kev xeem- qib RF coaxial connector. Los ntawm kev xaiv cov khoom siv tau zoo thiab cov qauv tsim, nws ua tiav siab - cov teeb liab raug xa mus thoob plaws DC-18 GHz zaus ntau, ua rau nws tsim nyog rau cov ntawv thov uas xav tau cov teeb liab nruj, xws li kev sib txuas lus sib txuas lus thiab radar systems.

 

The connector features a standard 50-ohm impedance design and a VSWR of ≤1.25, effectively minimizing signal reflection loss. With a frequency range extending from DC to 18 GHz, it meets the demands of high-frequency applications like 5G communications and satellite navigation. The outer conductor utilizes passivated stainless steel, offering a balance of corrosion resistance and mechanical strength, while the inner conductor features a gold-plated brass structure that enhances conductivity by minimizing contact resistance (≤1 mΩ for the outer conductor; ≤5 mΩ for the inner conductor). PTFE (polytetrafluoroethylene) is used for the insulator, providing excellent temperature resistance and low dielectric loss; this ensures an insulation resistance of >5 MΩ thiab txhawb lub dielectric withstanding voltage ntawm ntau dua los yog sib npaug rau 1000 V.

 

Connector kev ua tau zoo nyob ntawm qhov sib txuam ntawm cov ntaub ntawv thiab cov txheej txheem tsim khoom. Lub passivated stainless hlau sab nrauv neeg xyuas pib tiv taus 48 xuab moos ntawm cov ntsev tsuag tsis muaj corroding, ua rau nws haum rau sab nraum zoov lossis siab - av noo ib puag ncig. Lub thickness ntawm cov kub plating nyob rau hauv tus neeg xyuas pib yog nruj me ntsis tswj kom tsis txhob muaj kev sib cuag tiv thaiv thaum zam lub brittleness txuam nrog ntau plating thickness. PTFE insulator yog tsim los ntawm cov txheej txheem molding uas ua kom muaj qhov sib txawv ntawm cov khoom siv sab hauv thiab sab nrauv, yog li txo qhov kev pheej hmoo ntawm cov teeb liab to. Tsis tas li ntawd, lub connector yog tsim los rau lub neej ntev tshaj 500 mating cycles, ua tau raws li qhov yuav tsum tau muaj rau kev sib dhos nquag thiab disassembly hauv kev sim cov xwm txheej.

 

Lub connector no yog tsim tshwj xeeb rau kev kuaj cables xws li SS402, CXN3449, thiab 210A; cov neeg siv yuav tsum xyuas kom meej tias cable specifications phim lub connector interface. Tsis txhob siv lub zog ntau dhau thaum mating lossis unmating lub connector los tiv thaiv deformation ntawm lub puab conductor. Khaws rau hauv qhov chaw qhuav kom tiv thaiv kom tsis txhob ya raws los ntawm PTFE insulator, uas tuaj yeem degrade dielectric kev ua tau zoo. Ib ntus xyuas kev tiv thaiv tiv thaiv tom qab siv ntev; Yog hais tias qhov kev tiv thaiv tiv thaiv ntau tshaj 1 mΩ rau tus neeg xyuas pib sab nrauv lossis 5 mΩ rau tus neeg xyuas pib, kev hloov cov khoom txuas yog pom zoo kom ua kom cov teeb liab zoo. Cov khoom yog ntim rau hauv cov thawv uas muaj cov hnab ntim rov qab, yooj yim rau kev tswj hwm batch, thaum batch naj npawb cim (piv txwv li, 2022091101) tso cai rau kev tsim khoom.

 

Piv rau cov khoom sib txuas ua ke, cov khoom no muaj kev ua tau zoo los ntawm peb qhov kev txhim kho: ua ntej, kev siv qis - poob PTFE insulator es tsis txhob siv cov yas yas txo qhov siab - zaus teeb liab poob los ntawm 30%; Thib ob, kev sib xyaw ua ke ntawm kub -plated sab hauv tus neeg xyuas pib thiab cov hlau tsis muaj steel hlau sab nrauv txhim kho kev tiv thaiv kev tiv thaiv los ntawm 50%; thiab qhov thib peb, qhov optimized threaded locking mechanism ua kom lub VSWR tsawg dua los yog sib npaug rau 1.25 yog khaws cia txawm nyob rau hauv kev co. Cov kev txhim kho no ua rau lub teeb liab attenuation uas yog kwv yees li 1.5 dB / meter qis dua li cov qauv sib txuas hauv kev sim- cov ntawv thov qib (ntawm 18 GHz zaus band).
