LC High-Pass Fyuluta: High-Performance RF Solution ya 118-138MHz Band

khazikitsani kumbuyo kwa kukweza kopitilira muyeso mumayendedwe opanda zingwe ndi machitidwe a RF,Zosefera za LC zapamwambaamagwiritsidwa ntchito kwambiri m'mapulogalamu osiyanasiyana a VHF RF chifukwa cha kapangidwe kawo kakang'ono, kachitidwe kokhazikika, komanso kuyankha kosinthika. Mtundu wa ALCF118M138M45N woyambitsidwa ndi Apex Microwave ndi chitsanzo chofananira, chopangidwira bandi ya 118MHz mpaka 138MHz, potengera magwiridwe antchito komanso kudalirika.

Izimankhwalandi fyuluta ya FM yopangidwa paokha ndi Apex, yomwe imatha kupondereza makina owulutsa pawailesi ya FM mumtundu wa 87-108MHz, ndikudutsa bwino chizindikiro cha 118-138MHz mu gulu la VHF, chomwe chitha kuchepetsa ma siginecha osokera ndikupewa kusokoneza dongosolo.

TheLC high-pass filter ali ndi kutayika kochepa koyika kwa≤1.0dB ndi kutayika kwakukulu kwa≥15dB, kuwonetsetsa kufalikira kwazizindikiro kokhazikika komanso kuchepetsa kusokoneza kwamalingaliro. Zimapereka mwayi wopondereza mpaka≥40dB mu bandi ya 87.5-108MHz, kuwongolera bwino machitidwe odana ndi kusokoneza.

Monga wodziwa zambiriWopanga zosefera za LC, Apex wakhala akuyang'ana kwambiriLC RF fyuluta kapangidwendipo imathandizira zosowa zamakasitomala zamitundu yambiri. Themankhwalaali ndi mphamvu yonyamula mphamvu ya 50W, kutentha kwa ntchito kwa -40°C mpaka +85°C, ili ndi mawonekedwe amtundu wa N, ndipo imagwirizana ndi miyezo yachilengedwe ya RoHS.

Kuphatikiza pamitundu yokhazikika, timathandiziranso mayankho osiyanasiyana osinthika ndikupereka makondazosefera zapamwamba kwambirikukwaniritsa zofunikira zapadera mu kapangidwe, mawonekedwe ndi ntchito zamagetsi. Ndi yabwinoZosefera za LCyankho.
