IIsihlungi se-LC esingu-4500-5900MHzIfinyelela ekuhlungeni kwe-bandpass ngokunemba ngomklamo wenethiwekhi ye-LC olungiselelwe, ivumela ukudluliselwa okuncane kokunciphisa ngaphakathi kwe-4500-5900MHz ngenkathi icindezela ukuphazamiseka okungaphandle kwebhendi (ukwenqatshwa okungu->40dB ku-±100MHz). Lesi Sihlungi se-LC sihlanganisa izingxenye ze-Q eziphezulu ukuze kuncishiswe ukulahlekelwa kokufakwa futhi kwandiswe ukwenqatshwa, silondoloze ubuqotho besiginali. Ukuvikela kwayo kwe-electromagnetic kunikeza ukuzivikela okubili—kuvimba umsindo wangaphandle kuyilapho ukukhetha kwe-LC Filter kuqeda ukuphazamiseka okusele. Ngokuhambisana okunembile kwe-impedance engu-50Ω, ukubonakaliswa nokuphambuka kuyavinjelwa. Ukwakhiwa okuqinile kuqinisekisa ukuzinza kokushisa/komshini (-40°C kuya ku-+85°C), kususa ukugeleza kwemvamisa. Ngokubambisana, lezi zici zenza lesi Sihlungi se-LC sibe yisisombululo esithembekile sokuxhumana okubalulekile kokuphazamiseka.

Izici Zesihlungi se-LC

Ukuhlunga kwe-Bandpass Eqondile
Isihlungi se-LC esingu-4500-5900MHz sisebenzisa ukwakheka kwenethiwekhi ye-LC (inductor-capacitor) ethuthukisiwe ukudala ijika lokuphendula imvamisa elibukhali. Lesi sici se-bandpass enembile sivumela amasignali angaphakathi kobubanzi be-4500-5900MHz ukuthi adlule ngokuncipha okuncane ngenkathi ecindezela ngempumelelo imvamisa ngaphandle kwale band. Isihlungi sifinyelela izici zokugoqeka okuqinile (ngokuvamile ukwenqatshwa okungu->40dB ku-±100MHz offset), okudala "iwindi" lemvamisa elivikelayo elivimbela ukuphazamiseka kwesiteshi esiseduze.

Ukuhlanganiswa Kwezingxenye Eziphezulu
Ngokusebenzisa izingxenye ze-factor (Q) zekhwalithi ephezulu, i-LC Filter inciphisa ukulahlekelwa kokufakwa ngaphakathi kwe-passband ngenkathi ikhulisa ukwenqatshwa kwe-out-of-band. Ama-inductor nama-capacitor e-Q aphezulu anciphisa ukusatshalaliswa kwamandla, agcina ubuqotho besiginali ngenkathi ngesikhathi esifanayo evimba amaza angafuneki. Le nzuzo ephindwe kabili iqinisekisa ukuthi izimpawu ezifiselekayo zihlala ziqinile ngenkathi imithombo yokuphazamiseka incishiswa kakhulu.

Umklamo Wokuvikela Ama-Electromagnetic
Indlu encane yesihlungi se-LC ifaka ukuvikela kwe-electromagnetic okuvimbela umsindo we-RF wangaphandle ukuthi ungahlangani endleleni yesignali. Lokhu kuvikela, kuhlanganiswe nokukhetha kwemvamisa okungokwemvelo kwenethiwekhi ye-LC, kudala ukuzivikela kwezigaba ezimbili ekuphazamisekeni—okokuqala ngokuvimbela umsindo wangaphandle kanye nokwesibili ngokuhlunga noma yimaphi amaza angafuneki asele.

Ukuthuthukiswa Kokufaniswa Kokungazethembi
Ukufaniswa kwe-impedance okunembile (ngokuvamile i-50Ω) kulo lonkeIsihlungi se-LCUmklamo ka-'s unciphisa ukubonakaliswa kwesignali okungabangela ukuphazamiseka kwe-intermodulation. Ngokulondoloza izici ze-impedance ezihambisanayo, i-LC Filter ivimbela ukudalwa kwemikhiqizo emisha yokuphazamiseka ngaphakathi kohlelo lokuxhumana, igcina ubumsulwa besignali.

Ukuqina Kokushisa Nokwemishini
Ukwakhiwa okuqinile kwesihlungi se-LC kuqinisekisa ukusebenza okulinganayo phakathi nokushintshashintsha kwezinga lokushisa (-40°C kuya ku-+85°C) kanye nokucindezeleka komshini. Lokhu kuzinza kuvimbela ukuzulazula kwemvamisa okungavumela ukuphazamiseka ukuthi kungene ku-passband, kugcina ukucindezelwa okuthembekile kokuphazamiseka ezindaweni zokusebenza ezahlukahlukene.

Izinzuzo zefektri

I-Si Chuan Keenlion Microwave iyindlela enkulu yokukhetha ama-narrowband kanye nama-broadband, ahlanganisa amaza omsindo asukela ku-0.5 kuya ku-50 GHz. Aklanyelwe ukuphatha amandla okufaka angu-10 kuya ku-30 watts ohlelweni lokudlulisa olungu-50 ohm. Kusetshenziswa imiklamo ye-Microstrip noma ye-stripline, futhi ilungiselelwe ukusebenza kahle kakhulu.

Singakwazi futhiyenza ngendlela oyifisayoIsihlungi se-RF LC ngokwezidingo zakho. Ungangena ekhasini lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
