28-31GHz Waveguide Harmonic Bandstop Fyuluta

Mawonekedwe

Fyuluta ya Passive, yomwe imadziwikanso kuti LC fyuluta, ndi sefa yozungulira yomwe imapangidwa ndi kuphatikiza kwa inductance, capacitance ndi kukana, komwe kumatha kusefa ma harmonics amodzi kapena angapo.Chodziwika bwino komanso chosavuta kugwiritsa ntchito mawonekedwe a fyuluta ndikulumikiza inductance ndi capacitance mndandanda, zomwe zimatha kupanga njira yochepetsera yolumikizira ma harmonics akulu (3, 5 ndi 7);Zosefera zosinthidwa kamodzi, zosefera zochunidwa pawiri ndi zosefera zapamwamba zonse ndi zosefera.

Zosefera zokhazikika zimapangidwa ndi capacitor string reactance.

Malingana ndi chikhalidwe cha dongosolo, pali ma harmonics a 5, ndipo ma frequency a harmonic ndi 250Hz.

Panthawiyi, mphamvu ndi kachitidwe ka fyuluta yosasunthika zimagwirizana, ndipo zimamveka pafupipafupi 250Hz.Chifukwa kutsekeka kwathunthu kwa ma resonates awiriwa pamndandanda ndi 0, yomwe imadziwika kuti low impedance loop, panthawiyi, ma harmonic onse a 5 adzalowa mu fyuluta kuti akwaniritse zosefera.

Chifukwa cha zifukwa za ndondomeko, nthawi zambiri, fyuluta yokhazikika imatha kufika pafupifupi 245-250Hz, ndipo zotsatira zosefera zimatha kufika kupitirira 80%.

Ili ndi ntchito zosankhidwa pafupipafupi komanso zosefera m'mabwalo ndi makina amagetsi apamwamba kwambiri, ndipo imatha kupondereza ma siginecha opanda pake ndi phokoso kunja kwa band frequency.

Amagwiritsidwa ntchito pa ndege, zamlengalenga, radar, kulumikizana, kuwongolera zamagetsi, wailesi ndi kanema wawayilesi ndi zida zosiyanasiyana zamagetsi zamagetsi.

Mukamagwiritsa ntchito, samalani ndi kukhazikika bwino kwa chipolopolo, apo ayi zidzakhudza kuponderezana kwa gulu ndi flatness index.
