Fyuluta ya LC High-Pass: Yankho la RF Logwira Ntchito Kwambiri la 118-138MHz Band

kukhazikitsa maziko a kukweza kosalekeza kwa njira zolumikizirana zopanda zingwe ndi makina a RF,Zosefera za LC zodutsa kwambiriamagwiritsidwa ntchito kwambiri mu mapulogalamu osiyanasiyana a VHF RF chifukwa cha kapangidwe kake kakang'ono, magwiridwe antchito okhazikika, komanso kusinthasintha kwa mayankho. Mtundu wa ALCF118M138M45N womwe unayambitsidwa ndi Apex Microwave ndi chitsanzo chabwino, chopangidwira gulu la 118MHz mpaka 138MHz, poganizira magwiridwe antchito komanso kudalirika.

Izimalondandi fyuluta ya FM yopangidwa payokha ndi Apex, yomwe imatha kuletsa bwino makina owulutsira wailesi ya FM mu 87-108MHz, pomwe imadutsa bwino chizindikiro cha 118-138MHz mu VHF band, zomwe zingachepetse zizindikiro zosochera ndikupewa kusokoneza kwa makina.

TheLC high-pass filterer ili ndi kutayika kochepa kwa kuyika≤1.0dB ndi kutayika kwakukulu kwa kubweza kwa≥15dB, kuonetsetsa kuti chizindikirocho chikufalikira bwino komanso kuchepetsa kusokoneza kwa kuwala. Imapereka mphamvu yoletsa mpaka≥40dB mu gulu la 87.5-108MHz, zomwe zimapangitsa kuti makina azigwira bwino ntchito polimbana ndi kusokoneza.

Monga munthu wodziwa zambiriWopanga fyuluta ya LC, Apex yakhala ikuyang'ana kwambiri paKapangidwe ka fyuluta ya LC RFndipo imathandizira zosowa za makasitomala zosintha mitundu yosiyanasiyana.malondaili ndi mphamvu yonyamulira mphamvu ya 50W, kutentha kogwira ntchito kwa -40°C mpaka +85°C, ili ndi mawonekedwe a mtundu wa N, ndipo ikutsatira miyezo ya RoHS yokhudza chilengedwe.

Kuwonjezera pa mitundu yokhazikika, timathandizanso njira zosiyanasiyana zosinthidwa ndikupereka njira zosinthidwamapangidwe a fyuluta yodutsa kwambirikukwaniritsa zofunikira zapadera pa kapangidwe kake, mawonekedwe ake, ndi magwiridwe antchito amagetsi. Ndi malo abwino kwambiriLC fyuluta mankhwalayankho.
