28-31GHz Waveguide Harmonic Bandstop Lim

Nta

Passive lim, tseem hu ua LC lim, yog lub lim dej lim dej tsim los ntawm kev sib xyaw ua ke ntawm inductance, capacitance thiab tsis kam, uas tuaj yeem lim tawm ib lossis ntau qhov sib haum xeeb.Qhov feem ntau thiab yooj yim siv cov qauv lim dej yog txuas cov inductance thiab capacitance nyob rau hauv series, uas tuaj yeem tsim ib qho impedance bypass rau lub ntsiab harmonics (3, 5 thiab 7);Ib leeg tuned lim, ob chav tuned lim thiab high pass lim yog tag nrho cov lim passive.

Lub passive lim yog tsim los ntawm capacitor hlua reactance.

Raws li kev sib haum xeeb ntawm lub cev, piv txwv li, muaj 5th harmonics, thiab qhov sib haum xeeb yog 250Hz.

Nyob rau lub sijhawm no, lub peev xwm thiab kev ua haujlwm ntawm lub lim dej tsis sib haum, thiab lawv rov tshwm sim ntawm qhov zaus ntawm 250Hz.Vim hais tias tag nrho cov impedance ntawm ob resonates nyob rau hauv series yog 0, uas yog feem ntau hu ua lub low impedance voj, nyob rau lub sij hawm no, tag nrho cov 5th harmonic yuav ntws mus rau hauv lub passive lim kom tiav cov nyhuv filtering.

Vim yog txheej txheem txheej txheem, feem ntau hais lus, cov lim dej tsis zoo tuaj yeem ua tiav txog 245-250Hz, thiab cov nyhuv lim dej tuaj yeem ncav cuag ntau dua 80%.

Nws muaj kev xaiv zoo zaus thiab lim dej ua haujlwm hauv circuits thiab hluav taws xob siv hluav taws xob ntau zaus, thiab tuaj yeem cuam tshuam cov teeb liab tsis muaj txiaj ntsig thiab lub suab nrov sab nraud.

Nws yog siv rau aviation, aerospace, radar, kev sib txuas lus, hluav taws xob countermeasure, xov tooj cua thiab TV thiab ntau yam khoom siv hluav taws xob.

Thaum siv, xyuam xim rau qhov zoo hauv av ntawm lub plhaub, txwv tsis pub nws yuav cuam tshuam rau kev tawm tsam ntawm kev sib tsoo thiab kev sib tw.
