CAVITY RF FILTERS: ICYO BAKORA

Mubisanzwe bigizwe nibyuma binini hamwe na RF ihuza bike (2 kuri filteri na 3 kuri duplexers ihuza ibimenyetso bya Tx na Rx mukicyambu kimwe cya antenna).Nkuko bigaragara ku ishusho hepfo, muyungurura hagaragaramo imigozi myinshi kuruhande rumwe cyangwa nyinshi kumibiri yabo.Bimwe muribi bikoresho ni uguhuza imigozi, mugihe izindi zikoreshwa muguhuza isahani yo hejuru kuri chassis.

Kugirango ugabanye igihombo cya RF no kugera kuri Q cyangwa hejuru yo guhitamo bisabwa kugirango ubone igihombo gito mumashanyarazi yose no kwangwa bikabije hanze ya filteri, umubiri wa aluminiyumu uhora ushyizweho (hamwe na feza, umuringa, cyangwa zahabu, ariko gusa Kuri Umwanya Porogaramu).

Mu miyoboro yose idafite umugozi kuva 1G kugeza 5G, ndetse no muri sisitemu yitumanaho rya gisivili nigisirikare, RF Cavity Filters yabaye kandi ikomeza kuba uruganda rwinganda zidafite umugozi.Bafite umurongo mugari cyane, kuva kuri 50 MHz kugeza kuri 20 GHz.Bitewe n'uburebure bwabyo bwo hasi, bigenda biba bito uko inshuro ziyongera (umuvuduko wurumuri uhoraho kandi ubarwa nkibicuruzwa byumurongo wa signal ya RF hamwe nuburebure bwacyo).

Nubwo passband kubenshi mubisabwa bizwi cyane iri hagati ya 1% na 10% yumurongo wimikorere, RF Cavity Filters itanga uburyo butandukanye bwibikorwa bifatika kuko passband yabo ishobora gutandukana kuva munsi ya 0.5% kugeza kuri 20% yumurongo wibikorwa .Kugirango ubone imikorere myiza yakira mubidukikije bya RF, ubwinshi, niba atari byose, sisitemu idafite umugozi ikoresha RF Cavity Filters hagati ya Antenna na Radio (bandlimited signal LNA yinjiza kugirango yange imirongo yo hasi na yo hejuru hanze yimikorere ya sisitemu) .

Nkuko ibimenyetso bya Tx bisakuza cyane kuruta ibimenyetso byose byakira byerekanwa na 120 kugeza 150 dB, RF Cavity Filters nayo ikoreshwa kumurongo wa Tx kugirango barebe ko urusaku rwa PA hamwe n’ibyuka bihumanya kandi bitagira ingaruka kuri bo cyangwa ubundi bwoko bwa sisitemu idafite umugozi.
