Tsika Precision CNC Yakagadzirwa Sefa Cavity

CAVITY RF FILTERS: ZVINOITA

Iwo anowanzo sanganisira matombo makuru esimbi ane mashoma eRF ekubatanidza (2 yemafirita uye 3 emaduplexers anosanganisa Tx neRx masiginecha mune imwechete antenna chiteshi).Sezvinoratidzwa mumufananidzo uri pazasi, aya mafirita anoratidza akawanda screws padivi rimwe kana anopfuura emiviri yavo.Mamwe eaya masiruuru ari tuning screws, nepo mamwe anoshandiswa kusungirira ndiro yepamusoro kune chassis.

Kuti uderedze kurasikirwa kweRF uye uwane iyo yakakwira Q kana sefa sarudzo inodiwa kuti uwane kurasikirwa kwakaderera mukati mesefa passband uye kurambwa kwakapinza kunze kwesefa passband, muviri wealuminium unogara wakaputirwa (nesirivha, mhangura, kana kunyange goridhe, asi chete. zvekushandisa nzvimbo).

Mune ese mawaya network kubva ku1G kuenda ku5G, pamwe chete nevechiuto uye nemauto masisitimu ekutaurirana, RF Cavity Mafirita anga ari uye anoenderera mberi ari horse yeindasitiri isina waya.Ivo vane yakakura kwazvo frequency renji, kubva pa50 MHz kusvika kupfuura 20 GHz.Nekuda kwehuremu hwadzo hwakaderera, vanova madiki sezvo frequency inokwira (kumhanya kwechiedza kunogara uye kunoverengerwa sechigadzirwa cheiyo RF chiratidzo frequency uye wavelengths yayo).

Kunyangwe iyo passband yezvizhinji zvezvishandiso zvakakurumbira iri pakati pe1% ne10% yenguva yekushanda, RF Cavity Filters inopa huwandu hwakasiyana hwekushandisa sezvo passband yavo inogona kusiyanisa kubva pasi pe0.5% kusvika 20% yenguva yekushandisa. .Kuti uwane yakanakisa inogamuchira kuita munzvimbo chaiyo yeRF, mazhinji, kana asiri ese, asina waya masisitimu anoshandisa RF Cavity Mafirita pakati peAntenna neRadhiyo (yakaganhura iyo LNA yekuisa chiratidzo kuramba yakadzika uye yepamusoro ma frequency kunze kwemaitiro ehurongwa) .

Sezvo masaini eTx ane ruzha zvakanyanya kupfuura chero masaini anogashira ne120 kusvika 150 dB, RF Cavity Mafirita anoshandiswawo paTx siginecha kuve nechokwadi chekuti PA ruzha uye emissions zvakaganhurirwa uye hazvizvikanganise ivo pachavo kana chero imwe mhando isina waya system.
