Custom Precision CNC Machined Filter Cavity

ZOSEFA ZA CAVITY RF: ZIMENE AMACHITA

Nthawi zambiri amakhala ndi zitsulo zazikulu zokhala ndi zolumikizira zochepa za RF (2 za zosefera ndi 3 za ma duplex omwe amaphatikiza ma siginecha a Tx ndi Rx padoko limodzi).Monga momwe tawonetsera pachithunzichi, zoseferazi zimakhala ndi zomangira zambiri mbali imodzi kapena zingapo za matupi awo.Zina mwa zomangirazi ndi zomangira zomangira, pomwe zina zimagwiritsidwa ntchito kumangiriza mbale yapamwamba ku chassis.

Kuti muchepetse kutayika kwa RF ndikukwaniritsa kusankhidwa kwakukulu kwa Q kapena zosefera zomwe zimafunika kuti mupeze zotayika pang'ono muzosefera ndikukanidwa mwamphamvu kunja kwa fyuluta passband, thupi la aluminiyamu nthawi zonse limakutidwa (ndi siliva, mkuwa, kapena golide, koma kokha). kwa ntchito za space).

Mu maukonde onse opanda zingwe kuchokera ku 1G mpaka 5G, komanso m'njira zoyankhulirana zankhondo ndi zankhondo, Zosefera za RF Cavity zakhala zikugwirabe ntchito pamakampani opanda zingwe.Amakhala ndi ma frequency osiyanasiyana, kuyambira 50 MHz mpaka 20 GHz.Chifukwa cha kutalika kwawo kocheperako, amakhala ang'onoang'ono akamakwera pafupipafupi (kuthamanga kwa kuwala kumakhala kosasintha ndipo kumawerengedwa ngati chopangidwa ndi ma frequency a RF ndi mafunde ake).

Ngakhale chiphaso cha mapulogalamu ambiri otchuka chimakhala pakati pa 1% ndi 10% ya ma frequency ogwiritsira ntchito, Zosefera za RF Cavity zimapereka ntchito zingapo zothandiza popeza passband yawo imatha kusiyana kuchokera kuchepera 0.5% mpaka 20% ya ma frequency ogwiritsira ntchito. .Kuti mupeze zolandila zabwino kwambiri m'malo enieni a RF, makina ambiri opanda zingwe, ngati si onse, amagwiritsa ntchito Zosefera za RF Cavity pakati pa Antenna ndi Radio (amaletsa chizindikiro cholowetsa cha LNA kuti akane ma frequency otsika ndi apamwamba kunja kwa machitidwe) .

Popeza ma siginecha a Tx ndi okwera kwambiri kuposa ma siginecha aliwonse olandila ndi 120 mpaka 150 dB, Zosefera za RF Cavity zimagwiritsidwanso ntchito pa siginecha ya Tx kuwonetsetsa kuti phokoso la PA ndi zotulutsa zili ndi malire ndipo sizidzikhudza zokha kapena makina ena opanda zingwe.
