SMA Connector
1. Keeb Kwm thiab Tsim:
SMA hom RF coaxial connector tau tsim los ua OSM connector los ntawm Bendix thiab Omni-Spectra thaum lig 1950s. Nws yog ib qho ntawm feem ntau siv RF/microwave connectors thaum ntawd. Thaum xub thawj, SMA connectors tau tsim rau 0.141" semi-rigid coaxial cables thiab precision connectors rau microwave daim ntaub ntawv nyob rau hauv cov tub rog kev lag luam, lawv tau ntim nrog PTFE dielectric.
2. Ntau zaus thiab nrov:
Raws li cov xwm txheej ntawm lub sijhawm ntawd, vim nws qhov me me thiab muaj peev xwm ua haujlwm ntawm ntau zaus (qhov ntau zaus rau mating semi-rigid cables yog DC-18GHz; thaum mating saj zawg zog cables, nws yog DC{{2 }}.4GHz), nws sai sai tau nrov. Txawm tias cov millimeter yoj connectors tsim tom qab kuj tau txiav txim siab txog qhov teeb meem ntawm kev sib raug zoo ntawm cov neeg kho tshuab.
3. Nta thiab qhov zoo:
- Txuas mus rau qhov rov qab polarity interface hauv wireless systems.
- Lub chaw kub-plated hu tuaj yeem txo cov teeb liab poob.
- Kub-plated lub cev los txhim kho corrosion kuj.
- Muaj feem cuam tshuam cov cables thiab cov cuab yeej crimping.
- Machined connectors yog ntau ruaj.
4. Daim ntawv thov:
- Wireless LAN / RF daim ntawv thov / Wi-Fi daim ntawv thov.
- Xov tooj cua kav hlau txais xov / tsawg poob coaxial daim ntawv thov.
3.5 hli Connector
1. Taw qhia:
Lub 3.5mm connector yog ib tug connector nrog ib txoj kab uas hla ntawm lub sab nraud conductor ntawm 3.5mm, ib tug yam ntxwv impedance ntawm 50Ω, thiab ib tug kev twb kev txuas mechanism ntawm 1/4-36UNS-2 inch threads.
2. Keeb Kwm thiab Kev Txhim Kho:
Nyob rau nruab nrab -1970s, American Hewlett-Packard thiab Amphenol tau qhia txog 3.5mm connector nrog kev ua haujlwm zaus txog li 33GHz. Qhov no yog qhov ntxov tshaj plaws muaj xov tooj cua zaus coaxial connector nyob rau hauv millimeter yoj band.
3. Qhov txawv ntawm SMA Connector:
Ib qho pom tseeb sib txawv nrog SMA connectors yog 3.5mm siv cua nruab nrab. Tus neeg xyuas pib sab nrauv ntawm 3.5mm connector yog tuab dua li SMA connector, thiab cov neeg kho tshuab lub zog zoo dua. Yog li ntawd, tsis tsuas yog cov hluav taws xob kev ua tau zoo dua SMA connector, tab sis kuj cov neeg kho tshuab durability thiab kev ua tau zoo repeatability yog siab dua li ntawm SMA connector, ua rau nws tsim nyog rau siv nyob rau hauv kev lag luam kev xeem.
2.92 hli Connector
1. Kev Taw Qhia thiab Kev Sau Npe Variations:
Lub 2.92mm connector (qee lub tuam txhab hu cov connector 2.9mm los yog K-hom connector, thiab ib co manufacturers hu nws SMK, KMC, WMP4 connector, thiab lwm yam). Sab hauv txoj kab uas hla ntawm tus neeg xyuas pib yog 2.92mm, tus yam ntxwv impedance yog 50Ω, thiab kev sib txuas mechanism yog xov tooj cua zaus coaxial connector nrog 1/4-36UNS-2 inch threads. Nws cov qauv zoo ib yam li 3.5mm connector tab sis me dua.
2. Keeb Kwm Kev Txhim Kho:
Xyoo 1983, Wiltron's William.Old.Field senior engineer tau tsim ib hom tshiab ntawm 2.92mm / K hom connector raws li kev suav thiab kov yeej cov millimeter yoj connector qhia ua ntej. Txoj kab uas hla ntawm tus neeg xyuas pib yog 1.27mm, uas tuaj yeem muab tso rau hauv SMA thiab 3.5 connectors.
3. Kev ua tau zoo thiab kev lees paub:
Lub 2.92mm connector muaj hluav taws xob zoo nyob rau hauv DC -46GHz zaus band thiab yog mechanically sib xws nrog SMA connectors thiab 3.5mm connectors. Nws tau lees paub sai sai los ntawm feem ntau ntawm cov tuam ntxhab thiab tau dhau los ua ib qho ntawm feem ntau siv millimeter yoj connectors hauv ntiaj teb.
2.4 hli Connector
1. Kev Taw Qhia thiab Kev Sib Raug Zoo:
Lub connector nrog rau sab hauv txoj kab uas hla ntawm tus neeg xyuas pib ntawm 2.4mm thiab impedance ntawm 50 ohms yog mechanically sib xws nrog 1.85mm connector. Sab hauv txoj kab uas hla ntawm tus neeg xyuas pib ntawm 1.85mm connector yog 1.85mm, thiab impedance ntawm ob qho tib si yog 50 ohms. Lawv muaj qhov loj me me me me, yog li qhov ua haujlwm zaus ntau dua, nrog rau npe zaus ntawm 50GHz thiab 67GHz feem.
2. Ceev faj:
Nco ntsoov tias lawv yuav tsum tsis txhob txuas nrog 2.92mm, 3.5mm los yog SMA connectors, txwv tsis pub nws yuav ncaj qha ua rau lub txim ntawm connector puas.
Cov ntsiab lus
Nrog rau txoj kev loj hlob sai ntawm millimeter yoj thev naus laus zis thiab kev sib txuas lus ceev ceev, 2.92mm, 2.4mm, thiab 1.85mm connectors yog ntau thiab ntau dua dav siv hauv tub rog, aerospace, optoelectronics thiab lwm yam. Cov xwm txheej ntawm kev siv lawv ua ke nrog GPPO, GPO thiab lwm cov khoom sib txuas kuj tseem nce ntxiv thiab yuav tau piav qhia hauv cov ntawv txuas ntxiv.
