Cov hnub qub satellite Lower Earth Orbit (LEO) tab tom nthuav dav sai nrog kev hloov pauv ntawm 6G raws li cov kev txhim kho no. Thaum Starlink, OneWeb, thiab Project Kuiper xa cov hnub qub loj dua, thiab thaum hloov pauv ntawm 5G-Advanced mus rau 6G millimeter-wave frequencies txuas ntxiv mus, qhov kev thov rau kev faib tawm thiab lim cov teeb liab zoo yuav ntse heev.

Tshwj xeeb, LEO satellites xav tau cov khoom me me, muaj kev ntseeg siab uas muaj peev xwm ua haujlwm nrog cov zaus siab dua piv txwv li Ka, Q thiab V kom tso cai rau cov ntaub ntawv ntau ntxiv thoob plaws. Beamforming networks yog tsim nrog cov khoom siv passive precision, ib yam li cov chaw nres tsheb hauv av thiab cov neeg siv khoom.

Sichuan Keenlion Microwave Technology Co., Ltd yog ib lub tuam txhab nyob hauv Chengdu uas tsim cov khoom siv microwave thiab muaj ntau tshaj 20 xyoo ntawm kev paub txog kev tsim kho. Keenlion muab ntau yam khoom siv passive uas poob rau hauv pawg ua rau lawv cov npe khoom muaj cov lim dej rf, cov khoom faib hluav taws xob, cov khoom sib txuas lus, rf combiners thiab cavity duplexers, thiab ua haujlwm dhau ntawm DC txog 50GHz.

Keenlion's18-40GHz fais fab faibmuab hom kev ua tau zoo uas xav tau rau cov ntawv thov siv satellites thiab rau 6G thev naus laus zis tom ntej. Nws muaj qhov poob qis heev (feem ntau tsawg dua lossis sib npaug rau 1.0dB) nrog rau kev sib cais siab ntawm qhov chaw nres nkoj (feem ntau ntau dua 18dB) thiab tuaj yeem siv rau millimeter wave beamforming nrog phased array antennas thiab lub ntiaj teb chaw nres tsheb. Keenlion kuj tseem muaj kev hloov kho rau cov lus qhia xav tau hauv cov chaw ib puag ncig hnyav nrog lub sijhawm ua khoom ntau lawm ntawm cov qauv tsim qauv yog 3 lub lis piam thiab 6 lub lis piam rau cov qauv tsim kho.

Qhov kev thov rau cov khoom siv passive rf ua haujlwm siab yuav tsum nyob ruaj khov thaum lub khw rau kev sib txuas lus satellite txuas ntxiv nthuav dav.
