ItsindaAkayunguruzo ka LC ka 4500-5900MHzIgera ku gushungura neza kwa bandpass binyuze mu buryo bwa LC network, igatuma habaho kohereza gahoro gahoro mu buryo butabangamiye 4500-5900MHz mu gihe igabanya interferences ziturutse hanze y'umurongo (>40dB kwangwa kuri ±100MHz). Iyi LC Filter ihuza ibice bya Q kugira ngo igabanye igihombo cyo kwinjira no kongera kwangwa, ibungabunga ubusugire bw'ikimenyetso. Uburinzi bwayo bwa electromagnetic butanga ubwirinzi bubiri—bubuza urusaku rwo hanze mu gihe guhitamo kwa LC Filter bikuraho interferences zisigaye. Hamwe no guhuza impedance ya 50Ω neza, reflections na distortion birakumirwa. Imiterere ikomeye ituma ubushyuhe/mechanical bigumana (-40°C kugeza +85°C), bikuraho frequency drift. Hamwe, ibi bintu bituma iyi LC Filter iba igisubizo cyizewe cyo gutumanaho kw'ingenzi.

Ibiranga Akayunguruzo ka LC

Gushungura neza uburyo bwo gukoresha bandpass
Filter ya LC ya 4500-5900MHz ikoresha imiterere ya network ya LC (inductor-capacitor) iteye imbere kugira ngo ikore curve ya frequency response curve. Iyi miterere ya bandpass ikora neza yemerera ibimenyetso biri mu cyiciro cya 4500-5900MHz gutambuka nta kugabanya umuvuduko mu gihe bigabanya neza frequencies hanze y'iyi band. Filter igera ku miterere ya roll-off ikomeye (ubusanzwe >40dB yangwa kuri ±100MHz offset), ikora "idirishya" ririnda umuvuduko wa channel iri hafi.

Guhuza Ibice Bikomeye
Mu gukoresha ibice by’ingenzi (Q) bifite ubuziranenge, LC Filter igabanya igihombo cyo kwinjira mu gice cy’inzira mu gihe yongera kwangwa hanze y’umurongo. Inductor na capacitors za Q zigabanya ikwirakwira ry’ingufu, zigakomeza ubuziranenge bw’ibimenyetso mu gihe icyarimwe zifunga imirongo idakenewe. Iyi nyungu ebyiri zituma ibimenyetso byifuzwa bikomeza gukomera mu gihe amasoko y’inzitizi agabanuka cyane.

Igishushanyo mbonera cy'uburinzi bw'amashanyarazi
Agace gato k'akayunguruzo ka LC gafite uburinzi bw'amashanyarazi butuma urusaku rw'inyuma rwa RF rudahurira mu nzira y'ikimenyetso. Ubu burinzi, hamwe n'uburyo bwo guhitamo frequency bwa LC, butanga ubwirinzi bw'ibice bibiri ku buryo bwo kwirinda ingaruka—ubwa mbere bugahagarika urusaku rwo hanze, ubwa kabiri bugakuraho frequencies zidakenewe.

Uburyo bwo Guhuza Impedance
Guhuza impedance neza (ubusanzwe 50Ω) mu gihe cyoseAkayunguruzo ka LCIgishushanyo mbonera cyayo kigabanya ubwiyongere bw'ibimenyetso bishobora gutera kugoreka hagati y'amajwi. Mu gukomeza imiterere ya impedance ihoraho, LC Filter irinda ikorwa ry'ibicuruzwa bishya bibangamira itumanaho, ibi bikarinda ubuziranenge bw'ibimenyetso.

Ubushyuhe n'Ubukonje bw'Ikoranabuhanga
Imiterere ikomeye y'akayunguruzo ka LC ituma habaho imikorere ihamye mu ihindagurika ry'ubushyuhe (-40°C kugeza +85°C) ndetse n'imihangayiko ya mekanike. Uku guhagarara neza birinda ubwinshi bw'amajwi bushobora gutuma ubwinjirane bw'amajwi bwinjira mu murongo w'inzira, bigatuma habaho gukumira ubwinjirane mu buryo bwizewe mu duce dutandukanye tw'imikorere.

Ibyiza by'uruganda

Microwave ya Si Chuan Keenlion ni amahitamo menshi mu miterere ya narrowband na broadband, ifite umurongo wa frequencies kuva kuri 0.5 kugeza kuri 50 GHz. Yagenewe gutwara imbaraga za watts 10 kugeza kuri 30 muri sisitemu yo kohereza ya 50-ohm. Imiterere ya microstrip cyangwa stripline irakoreshwa, kandi ikanozwa kugira ngo ikore neza.
