3dB Hybrid Coupler

The 3dB hybrid coupler ndi chipangizo chomwe chimagawaniza siginecha m'magulu awiri ofanana amplitude ndi kusiyana kwa gawo la 90 °. Pakadali pano, pali ma 800-2500MHz wide-band 3dB hybrid couplers, ndi 3dB Hybrid couplers omwe amagwiritsidwa ntchito kuphatikiza ma siginecha a ma frequency omwewo. Zinthu: Phatikizani GSM, DCS, DTV, WLAN, WCDMA, ndi CDMA2000. CDMA800 ndi zizindikiro zina mu njira imodzi kapena zingapo ndikuzidyetsa mu kachitidwe kagawidwe;3dB Hybrid Coupler yokhala ndi ma frequency amtundu umodzi komanso ma frequency ophatikizika ambiri okhala ndi kutayika kotsika, kusinthasintha kwamagulu ang'onoang'ono, ndi mafunde oyimilira Ang'onoang'ono, odzipatula kwambiri; mphamvu zazikulu; kudalirika kwakukulu (anti-vibration, anti-shock), kukana kutentha kwambiri, 3dB Hybrid Coupler corrosion resistance, ndi madzi.

Chiyambi cha 3dB hybrid coupler: The 3dB hybrid coupler imatchedwanso chophatikizira chomwechi, 3dB Hybrid Coupler imatha kuyesa mphamvu yotumizira mbali ina ya chingwe chotumizira, 3dB Hybrid Coupler ndipo imatha kugawa chizindikiro cholowera m'magulu awiri ofanana ndi 90 ° gawo Lopanda chizindikiro. Amagwiritsidwa ntchito kwambiri pophatikiza ma siginecha angapo kuti apititse patsogolo kuchuluka kwa ma siginoloji otulutsa. Amagwiritsidwa ntchito kwambiri pamakina ophimba m'nyumba pophatikiza ma siginecha oyambira. Zili ndi zotsatira zabwino pamalo ano.

Kugwiritsa ntchito mlatho wa 3dB: Kutayika kwa mlatho wa 3dB ndi 3.2, kudzipatula kulinso 25, ndipo mafunde oyimirira ndi pafupifupi. Koma pali madoko awiri linanena bungwe, mwachitsanzo, 3dB Zophatikiza Coupler awiri athandizira 30 linanena bungwe ndi awiri 27. Doko linanena bungwe la 3dB mlatho akhozanso kukhazikitsidwa mopanda malire, athandizira awiri ndi linanena bungwe limodzi, athandizira limodzi ndi linanena bungwe awiri, 3dB Zophatikiza Coupler awiri. kulowetsa ndi kutulutsa ziwiri ndizotheka, doko linanso limalumikizidwa Ingonyamula katundu ndi mphamvu zokwanira. Ngati katunduyo sanalumikizidwe, 3dB hybrid coupler idzachotsedwa kufakitale, yomwe ilibe mphamvu ngati katundu wina. Komabe, chiŵerengero choyimirira chikakwera, 3dB Hybrid Coupler ndi 3dB yokha yomwe ingagwiritsidwe ntchito. Kuphatikiza apo, mphamvu yolimbana ndi chipangizocho iyeneranso kuganiziridwa.
Monga wopangaRF passive zigawo, titha kupanga mwapadera zogawa mphamvu, ma couplers, ndi zophatikizira ngati yankho lanu, kotero tikukhulupirira titha kukuthandizani nthawi iliyonse.
