LC High-Pass Sefa: Yepamusoro-Performance RF Solution ye118-138MHz Band

inst iyo yekumashure yekuenderera mberi kwekusimudzira mune isina waya yekutaurirana uye RF masisitimu,LC mafirita epamusoro-pasianoshandiswa zvakanyanya mumhando dzakasiyana dzeVHF RF zvikumbiro nekuda kweiyo compact chimiro, yakagadzikana kuita, uye inoshanduka mhinduro. Iyo ALCF118M138M45N modhi yakatangwa neApex Microwave muenzaniso wakajairwa, wakagadzirirwa bhendi re118MHz kusvika ku138MHz, tichifunga nezvekuita uye kuvimbika.

IzvichigadzirwaiFM sefa yakazvimiririra yakagadziridzwa neApex, inogona kudzvanya masisitimu eredhiyo eredhiyo mu87-108MHz renji, ichiri kupfuura nepainonongedzwa chiratidzo che118-138MHz mubhendi reVHF, iyo inogona kuderedza masisitimu akarasika uye kudzivirira kukanganiswa kwehurongwa.

TheLC yakakwira-pass sefar ine yakaderera yekuisa kurasikirwa kwe≤1.0dB uye kurasikirwa kwakanyanya kwekudzoka kwe≥15dB, kuve nechokwadi chekufambisa kwemasaini kwakagadzikana uye kuderedza kukanganiswa kwekufungisisa. Inopa kudzvinyirira kugona kwekusvika≥40dB mu87.5-108MHz bhendi, zvinobudirira kuvandudza sisitimu yekurwisa-kupindira kuita.

Semunhu ane ruzivoLC mugadziri wesefa, Apex yakagara yakatarisaLC RF sefa dhizainiuye inotsigira vatengi 'multi-bhendi kugadzirisa zvinodiwa. Thechigadzirwaine simba rekutakura simba re50W, tembiricha yekushanda ye -40°C kusvika +85°C, yakashongedzerwa neN-mhando interface, uye inoenderana neRoHS mazinga ezvakatipoteredza.

Kuwedzera kune akajairwa mamodheru, isu tinotsigirawo akasiyana-siyana akagadziridzwa mhinduro uye tinopa akagadziridzwahigh-pass filter designskusangana nezvinodiwa zvakakosha muchimiro, interface uye kushanda kwemagetsi. Chinhu chakanakaLC sefa chigadzirwamhinduro.
