Firita yeLC High-Pass: Mhinduro yeRF yeHigh-Performance ye118-138MHz Band

kutanga mamiriro ekuvandudzwa kunogara kuripo mukutaurirana kusina waya uye masisitimu eRF,Mafirita eLC ane simba repamusoroanoshandiswa zvakanyanya mumhando dzakasiyana dzeVHF RF nekuda kwechimiro chayo chidiki, kushanda kwakasimba, uye mhinduro inochinjika. Modhi yeALCF118M138M45N yakatangwa neApex Microwave muenzaniso wakajairika, wakagadzirirwa bhendi re118MHz kusvika 138MHz, tichifunga nezvekushanda uye kuvimbika.

Izvichigadzirwaifirita yeFM yakagadzirwa yega neApex, iyo inogona kudzvinyirira zvinobudirira masisitimu eredhiyo yeFM ari muchikamu che87-108MHz, uku ichipfuura nepakati pechiratidzo che118-138MHz mubhendi reVHF, izvo zvinogona kuderedza masaini anorasika uye kudzivirira kupindira kwesisitimu.

IyoLC high-pass filterr ine kurasikirwa kwakaderera kwekupinza kwe≤1.0dB uye kurasikirwa kwakanyanya kwekudzoka kwe≥15dB, zvichiita kuti chiratidzo chienderane zvakanaka uye kuderedza kupindirana kwechiedza. Inopa kugona kwekudzvanya kusvika ku≥40dB mubhendi re87.5-108MHz, zvichinyatso vandudza mashandiro esystem ekudzivirira kukanganiswa.

Semunhu ane ruzivoMugadziri we LC firita, Apex yagara ichinyanya kutarisa paDhizaini yefaira reLC RFuye inotsigira zvinodiwa nevatengi pakugadzirisa mabhendi akawanda.chigadzirwaine simba rekutakura simba re50W, tembiricha yekushanda inosvika -40°C kusvika +85°C, ine interface yemhando yeN, uye inoenderana neRoHS Environmental Standards.

Kuwedzera kumamodheru akajairwa, tinotsigirawo mhinduro dzakasiyana-siyana dzakagadziriswa uye tinopa dzakagadziriswamagadzirirwo efirita yepamusoro-sorokusangana nezvinodiwa zvakakosha muchimiro, chimiro uye mashandiro emagetsi. Ndiyo yakanaka kwazvoLC firita chigadzirwamhinduro.
