Imikhiqizo

28-31GHz Waveguide Harmonic Bandstop Isihlungi

Incazelo emfushane:

Isihlungi se-Waveguide siwuhlobo lwesihlungi somugqa wokudlulisela.Ngokuvamile, isihlungi se-waveguide sakhiwe ngokungaqhubeki namasegimenti womugqa wokudlulisela.Kokubili kungalingana nezinto ezihambisanayo zepharamitha namasekhethi, ukungaqhubeki kwe-waveguide kunikeza ukusabela okulinganayo, izingxenye zomugqa wokudlulisela, ama-resonator alinganayo nokunye.

Lapho siklama isihlungi, ngokuvamile sidinga ukucabangela ngokugcwele indawo engokoqobo yokusetshenziswa kwekhasimende, izimfuneko zokusebenza kwekhasimende (ezifana nevolumu yesihlungi, ukulahlekelwa, ukuphuma kwefrikhwensi yebhendi, isistimu yokucindezela namandla okusebenza) kanye nobuchwepheshe bokucubungula ukuze kuzuzwe umphumela weprimiyamu wesihlungi. .

Izici

Isihlungi se-Passive, esaziwa nangokuthi isihlungi se-LC, siyisifunda sokuhlunga esakhiwe inhlanganisela ye-inductance, capacitance kanye nokumelana, okungase kuhlunge i-harmonics eyodwa noma ngaphezulu.Isakhiwo sokuhlunga esivame kakhulu nesisebenziseka kalula ukuxhuma i-inductance kanye ne-capacitance ochungechungeni, olungakha i-impedance bypass ephansi yama-harmonics ayinhloko (3, 5 kanye ne-7);Isihlungi esishuniwe esisodwa, isihlungi esishunwe kabili nesihlungi sokudlula okuphezulu konke kuyizihlungi ezingenzi lutho.

Isihlungi se-passive sakhiwe ukusabela kweyunithi ye-capacitor.

Ngokwesimo se-harmonic sohlelo, isibonelo, kukhona ama-harmonics angu-5, futhi imvamisa ye-harmonic ingu-250Hz.

Ngalesi sikhathi, amandla kanye nokusabela kwesihlungi se-passive kuyafaniswa, futhi zizwakala ku-frequency engu-250Hz.Ngenxa yokuthi ukuvinjelwa okuphelele kwama-resonates amabili ochungechungeni kungu-0, okuvame ukwaziwa ngokuthi i-low impedance loop, ngalesi sikhathi, yonke i-harmonic yesi-5 izogelezela kusihlungi sokwenziwa ukuze kuzuzwe umphumela wokuhlunga.

Ngenxa yezizathu zenqubo, uma sikhuluma nje, isihlungi sokwenziwa singafinyelela cishe ku-245-250Hz, futhi umphumela wokuhlunga ungafinyelela ngaphezu kwama-80%.

Inokukhethwa kwamafrikhwensi okuhle nemisebenzi yokuhlunga kumasekhethi kanye nezinhlelo ze-electronic high-frequency, futhi ingacindezela amasignali angenamsebenzi nomsindo ngaphandle kwebhendi yefrikhwensi.

Isetshenziselwa izindiza, i-aerospace, i-radar, ukuxhumana, i-electronic countermeasure, umsakazo nethelevishini kanye nemishini yokuhlola ye-elekthronikhi ehlukahlukene.

Uma usebenzisa, naka ukugxila okuhle kwegobolondo, ngaphandle kwalokho kuzothinta ukuphuma kwe-band ukucindezelwa kanye ne-flatness index.
