Mu makina ogawa ma antenna (DAS), kodi ogwiritsa ntchito angasankhe bwanji ma power splitters ndi ma couplers oyenera?

Mu ma network amakono olumikizirana, Distributed Antenna Systems (DAS) yakhala njira yofunika kwambiri kwa ogwiritsa ntchito kuthana ndi kufalikira kwamkati, kukulitsa mphamvu, komanso kutumiza ma signal a multi-band. Kugwira ntchito kwa DAS sikudalira kokha ma antenna okha komanso kumakhudzidwa kwambiri ndi zinthu zosiyanasiyana zosagwira ntchito mkati mwa dongosololi, makamaka ma power splitters ndi ma directional couplers. Kusankha zigawo zoyenera kumatsimikizira mwachindunji mtundu wa kufalikira kwa ma signal komanso magwiridwe antchito a netiweki yonse.

I. Udindo wa Ogawa Mphamvu mu DAS

Zogaŵira zamagetsi zimagwiritsidwa ntchito makamaka kugawa zizindikiro za siteshoni yoyambira mofanana ku madoko angapo a antenna amkati, zomwe zimathandiza kuti zifike m'malo osiyanasiyana.

Mfundo Zofunika Kuziganizira Posankha Power Splitters:

Kutayika kwa Kuyika
Kutayika kochepa kwa ma insertion kumapangitsa kuti ma signal afalikire bwino kwambiri. M'ma projekiti akuluakulu ophimba mkati, ogwiritsa ntchito nthawi zambiri amasankha ma power splitter osataya kwambiri kuti achepetse kuwononga mphamvu.

Kupatula Doko
Kutalikirana kwambiri kumachepetsa kulankhulana pakati pa madoko, zomwe zimapangitsa kuti zizindikiro zisamayende bwino pakati pa ma antenna osiyanasiyana.

Kutha Kusamalira Mphamvu
Muzochitika zogwiritsa ntchito mphamvu zambiri (monga DAS m'malo akuluakulu), ndikofunikira kusankha zogawa mphamvu zomwe zimatha kugwiritsa ntchito mphamvu zambiri zolowera kuti zitsimikizire kuti ntchitoyo ikuyenda bwino kwa nthawi yayitali.

II. Kugwiritsa Ntchito Ma Couplers mu DAS

Zolumikizira zimagwiritsidwa ntchito kutulutsa gawo la chizindikiro kuchokera ku thunthu lalikulu kuti zipereke ma antenna m'malo enaake amkati, monga makonde kapena magawo a pansi.

Mfundo Zofunika Kuziganizira Posankha Okwatirana:

Mtengo Wolumikizira
Mitengo yolumikizirana yodziwika bwino ikuphatikizapo 6 dB, 10 dB, ndi 15 dB. Mtengo wolumikizirana umakhudza mphamvu yomwe imaperekedwa ku ma antenna. Ogwiritsa ntchito ayenera kusankha mtengo woyenera wolumikizirana kutengera zomwe zimafunika komanso kuchuluka kwa ma antenna.

Malangizo ndi Kudzipatula
Zolumikizira zamagetsi zowongolera kwambiri zimachepetsa kuwunikira kwa chizindikiro, zomwe zimapangitsa kuti chigwirizano chachikulu cha thunthu chikhale cholimba.

Makhalidwe Otsika a PIM
Mu makina a 5G ndi ma DAS amitundu yambiri, ma couple a Passive Intermodulation (PIM) ochepa ndi ofunikira kwambiri kuti apewe kusokonezana kwa ma intermodulation ndikuwonetsetsa kuti chizindikirocho chili bwino.

III. Njira Zothandiza Zosankhira Ogwira Ntchito

Mu ntchito zauinjiniya, ogwiritsa ntchito nthawi zambiri amaganizira zinthu zotsatirazi kuti asankhe bwino ma power splitters ndi ma couplers:

Mulingo wa Zochitika: Nyumba zazing'ono zamaofesi zitha kugwiritsa ntchito zogawa magetsi za njira ziwiri kapena zitatu, pomwe mabwalo akuluakulu amasewera kapena ma eyapoti amafunikira kuphatikiza zogawa magetsi za magawo ambiri ndi zolumikizira zosiyanasiyana.

Thandizo la Mabandi Ambiri: DAS yamakono iyenera kuthandizira ma frequency kuyambira 698–2700 MHz komanso mpaka 3800 MHz. Ogwiritsa ntchito amafunika kusankha zinthu zopanda ntchito zomwe zimagwirizana ndi ma frequency band onse.

Kulinganiza kwa Dongosolo: Mwa kuphatikiza bwino zida zogawa mphamvu ndi zolumikizira, ogwiritsa ntchito amatha kuwonetsetsa kuti chizindikirocho chili ndi mphamvu yofanana m'malo onse, kupewa malo osawonekera kapena kufalikira kwambiri.

Chengdu Concept Microwave Technology CO.,Ltd ndi kampani yopanga zinthu zamakina a microwave.Zigawo za microwave zopanda ntchito ya dongosolo la DAS, kuphatikizapo fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop, duplexer, Power divider ndi cholumikizira cholunjika. Zonsezi zitha kusinthidwa malinga ndi zomwe mukufuna.
