M'machitidwe a antenna (DAS), ogwiritsira ntchito angasankhe bwanji zogawa mphamvu zoyenera ndi ma coupler?

M'maukonde amakono olumikizirana, Distributed Antenna Systems (DAS) yakhala yankho lofunikira kwa ogwiritsa ntchito kuthana ndi kufalikira kwamkati, kukulitsa mphamvu, komanso kutumiza ma siginecha amitundu yambiri. Kuchita kwa DAS sikungodalira tinyanga zokha komanso kumakhudzidwa kwambiri ndi zigawo zosiyanasiyana zomwe zili mkati mwadongosolo, makamaka zogawa mphamvu ndi ma coupler otsogolera. Kusankha zigawo zoyenera mwachindunji kumatsimikizira mtundu wa kuwulutsa kwa ma siginecha komanso magwiridwe antchito apaintaneti.

I. Udindo wa Magetsi Amphamvu mu DAS

Magetsi ogawa magetsi amagwiritsidwa ntchito kugawa chimodzimodzi ma siginecha oyambira kumadoko angapo amkati amkati, ndikupangitsa kufalikira kumadera angapo.

Mfundo Zofunika Kwambiri Posankha Magetsi Amagetsi:

Kutayika Kwawo
Kutayika kwapang'onopang'ono kumapangitsa kuti ma signature aziyenda bwino. M'mapulojekiti akuluakulu a m'nyumba, ogwira ntchito nthawi zambiri amasankha zogawa magetsi zotayika pang'ono kuti achepetse kuwonongeka kwa magetsi.

Port Isolation
Kudzipatula kwakukulu kumachepetsa crosstalk pakati pa madoko, kuwonetsetsa kudziyimira pawokha pakati pa tinyanga tosiyanasiyana.

Mphamvu Yogwira Ntchito
Muzochitika zogwiritsira ntchito mphamvu zamphamvu (mwachitsanzo, DAS m'malo akuluakulu), ndikofunikira kusankha zogawa magetsi zomwe zimatha kugwiritsa ntchito mphamvu zowonjezera kuti zitsimikizire kugwira ntchito kwa nthawi yaitali.

II. Kugwiritsa Ntchito Ma Couplers mu DAS

Maanja amagwiritsidwa ntchito kutulutsa gawo la siginecha kuchokera ku thunthu lalikulu kuti adyetse tinyanga m'malo ena am'nyumba, monga makonde kapena magawo apansi.

Mfundo Zofunika Kwambiri Posankha Anthu Okwatirana:

Kulumikizana Mtengo
Miyezo yolumikizana yodziwika bwino imaphatikizapo 6 dB, 10 dB, ndi 15 dB. Mtengo wolumikizana umakhudza mphamvu zomwe zimaperekedwa ku tinyanga. Ogwiritsa ntchito asankhe mtengo wolumikizana woyenerera potengera zomwe akufuna komanso kuchuluka kwa tinyanga.

Directivity ndi Kudzipatula
Ma couplers apamwamba kwambiri amachepetsa kuwonetsera kwa zizindikiro, kupititsa patsogolo kukhazikika kwa ulalo waukulu wa thunthu.

Makhalidwe Ochepa a PIM
Mu machitidwe a 5G ndi ma multi-band DAS, ma couplers otsika a Passive Intermodulation (PIM) ndi ofunika kwambiri kuti apewe kusokonezeka kwa intermodulation ndikuwonetsetsa khalidwe la chizindikiro.

III. Njira Zosankhira Othandizira

Pakutumizidwa kwa uinjiniya, ogwiritsa ntchito nthawi zambiri amaganizira zinthu zotsatirazi kuti asankhe mozama zogawa magetsi ndi ma coupler:

Mulingo Wowonekera: Nyumba zazing'ono zamaofesi zitha kugwiritsa ntchito zida za 2-way kapena 3-way, pomwe mabwalo amasewera akulu kapena ma eyapoti amafunikira kuphatikiza masitepe ogawa magetsi ndi ma coupler osiyanasiyana.

Thandizo la Magulu Ambiri: DAS yamakono iyenera kuthandizira mafupipafupi kuyambira 698-2700 MHz ndipo ngakhale kupitirira 3800 MHz. Othandizira ayenera kusankha zigawo zomwe zimagwirizana ndi ma frequency band.

Kulinganiza Kwadongosolo: Pophatikiza zogawitsa magetsi ndi ma coupler, ogwiritsira ntchito amatha kuonetsetsa kuti ma siginecha ali ndi mphamvu m'malo onse, kupewa kubisa malo osawona kapena kuphimba kwambiri.

Chengdu Concept Microwave Technology CO., Ltd ndi katswiri wopangaZigawo zopanda ma microwave kwa dongosolo la DAS, kuphatikiza fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop, duplexer, Power divider ndi directional coupler. Zonse zitha kusinthidwa malinga ndi zomwe mukufuna.
