Achogawa mphamvuamagawa chizindikiro chomwe chikubwera m'zigawo ziwiri (kapena zambiri) zotuluka. M'malo abwino, chogawa mphamvu chikhoza kuonedwa kuti ndi chochepa, koma pochita nthawi zonse pali kutaya mphamvu. Chifukwa ndi netiweki yolumikizana, chophatikizira chamagetsi chimatha kugwiritsidwanso ntchito ngati chophatikizira mphamvu, pomwe madoko awiri (kapena kupitilira apo) amagwiritsidwa ntchito kuphatikiza ma siginecha olowetsa kukhala chinthu chimodzi. Mwachidziwitso, chogawa mphamvu ndi chophatikizira mphamvu chikhoza kukhala chigawo chomwecho, koma pochita pangakhale zofunikira zosiyana za ophatikiza ndi ogawa, monga kugwiritsira ntchito mphamvu, kufananitsa gawo, machesi a doko ndi kudzipatula.

Ogawa mphamvu ndi ophatikiza nthawi zambiri amatchedwa ogawa. Ngakhale izi ndi zolondola mwaukadaulo, mainjiniya nthawi zambiri amasunga mawu oti "splitter" kuti atanthawuze mawonekedwe otsika mtengo omwe amagawanitsa mphamvu pa bandwidth yayikulu kwambiri, koma amakhala ndi kutayika kwakukulu komanso kugwiritsa ntchito mphamvu pang'ono.

Mawu akuti "divider" amagwiritsidwa ntchito nthawi zambiri pamene chizindikiro chomwe chikubwera chidzagawanika mofanana pazotsatira zonse. Mwachitsanzo, ngati pali ma doko awiri otulutsa, iliyonse ipeza zosakwana theka la siginecha yolowera, bwino -3 dB poyerekeza ndi siginecha yolowera. Ngati pali madoko anayi otulutsa, doko lililonse litha kupeza pafupifupi gawo limodzi mwa magawo atatu a sigino, kapena -6 dB poyerekeza ndi siginecha yolowera.

Kudzipatula

Posankha mtundu wogawaniza kapena chophatikizira, ndikofunikira kuganizira kudzipatula. Kudzipatula kwakukulu kumatanthauza kuti zizindikiro za zochitika (mu chophatikizira) sizisokonezana, ndipo mphamvu iliyonse yomwe siinatumizidwe kuzinthuzo imatayika m'malo motumizidwa ku doko lotulutsa. Mitundu yosiyanasiyana ya ogawa amasamalira izi m'njira zosiyanasiyana. Mwachitsanzo, pagawo la Wilkinson, chotsutsa chimakhala ndi mtengo wa 2Z0 ndipo chimangiriridwa pazotuluka. Mu quadrature coupler, doko lachinayi lili ndi kutha. Kuthetsa sikutaya mphamvu pokhapokha ngati chinachake choipa chichitika, monga amp amp amalephera kapena amplifiers ali ndi magawo osiyanasiyana.

Mitundu Yogawikana

Pali mitundu yambiri ndi ma subtypes ogawa mphamvu kapena ophatikiza. Zina mwazodziwika kwambiri ndi izi:

Wilkinson power divider

Wogawanitsa wa Wilkinson amagawa siginecha yolowera kukhala ma siginecha awiri ofanana, kapena kuphatikiza ma siginecha awiri ofanana kukhala amodzi mbali ina. Wogawanitsa wa Wilkinson amadalira zosintha za quarter-wave kuti zigwirizane ndi doko logawanika. Chokanizira chimayikidwa pazotulutsa, pomwe sichimawononga chizindikiro cholowera pa Port 1. Izi zimawongolera kwambiri kudzipatula ndikulola madoko onse kuti agwirizane. Wogawanitsa wamtunduwu nthawi zambiri amagwiritsidwa ntchito pamakina amtundu wa ma radio pafupipafupi chifukwa amatha kupereka kudzipatula pakati pa madoko otulutsa. Potsitsa magawo ochulukirapo a quarter wave, a Wilkinson amatha kuthana ndi ma 9: 1 ma bandwidths amagetsi ankhondo.

Monga momwe dzinalo limatanthawuzira, chogawa chamagetsi cha RF/microwave chimagawaniza siginecha kukhala ma siginecha awiri ofanana ndi ofanana (mwachitsanzo mu gawo). Itha kugwiritsidwanso ntchito ngati chophatikizira mphamvu, pomwe doko wamba ndilotulutsa ndipo madoko awiri ofanana amagwiritsidwa ntchito ngati zolowetsa. Zofunikira zofunika zikagwiritsidwa ntchito ngati chogawa mphamvu zimaphatikizira kutayika kwa kuyika, matalikidwe ndi gawo lolingana pakati pa mikono, ndi kutayika kobwerera. Pakuphatikizika kwamphamvu kwa ma siginecha osagwirizana, chofunikira kwambiri ndikudzipatula, komwe ndiko kutayika koyikirako kuchokera ku doko limodzi lofanana lamagetsi kupita ku lina.

Ogawa MphamvuMawonekedwe

• Zogawa zamagetsi zitha kugwiritsidwa ntchito ngati zophatikizira kapena zogawa

• Wilkinson ndi High kudzipatula mphamvu dividers amapereka kwambiri kudzipatula, kutsekereza chizindikiro kuyankhulana pakati pa madoko zotuluka

• Kuyika kochepa ndi kubwereranso kutaya

• Wilkinson ndi zogawa mphamvu zodzitchinjiriza zimapereka matalikidwe apamwamba kwambiri (<0.5dB) ndi (<3°)

Si Chuan Keenlion Microwave kusankha kwakukulu kwa zida za 2-way zogawa mphamvu mumipanda yocheperako komanso ma Broadband, kuphimba ma frequency kuchokera ku DC kupita ku 50 GHz. Amapangidwa kuti azigwira kuchokera pa 10 mpaka 30 watts kulowetsa mphamvu mu 50-ohm transmission system. Mapangidwe a Microstrip kapena stripline amagwiritsidwa ntchito, ndikukonzedwa kuti azigwira bwino ntchito.

Mayunitsi amabwera muyezo wokhala ndi zolumikizira za SMA kapena N zazikazi, kapena 2.92mm, 2.40mm, ndi zolumikizira za 1.85mm pazigawo zapamwamba kwambiri.

Titha kusinthanso chogawa mphamvu malinga ndi zomwe mukufuna. Mutha kulowa patsamba losintha kuti mupereke zomwe mukufuna.
