Isihlungi Se-LC High-Pass: Isixazululo Se-RF Esisebenza Kakhulu Sebhendi engu-118-138MHz

ukufaka isizinda sokuthuthukiswa okuqhubekayo kwezokuxhumana okungenantambo kanye nezinhlelo ze-RF,Izihlungi ze-LC high-passzisetshenziswa kabanzi ezinhlelweni ezahlukene ze-VHF RF ngenxa yesakhiwo sazo esihlangene, ukusebenza okuzinzile, kanye nokuphendula okuvumelana nezimo. Imodeli ye-ALCF118M138M45N eyethulwe i-Apex Microwave iyisibonelo esijwayelekile, esidizayinelwe ibhendi engu-118MHz ukuya ku-138MHz, kucatshangelwa kokubili ukusebenza nokwethembeka.

Lokhuumkhiqizoyisihlungi se-FM esakhiwe ngokuzimela yi-Apex, esingacindezela ngempumelelo izinhlelo zokusakaza zomsakazo we-FM ebangeni le-87-108MHz, kuyilapho sidlula ngokuphumelelayo isignali eqondiwe engu-118-138MHz ebhendi ye-VHF, enganciphisa amasignali alahlekile futhi igweme ukuphazamiseka kohlelo.

II-LC high-pass filterr inokulahlekelwa okuphansi kokufaka kwe≤1.0dB kanye nokulahlekelwa okukhulu kwembuyiselo ye≥I-15dB, iqinisekisa ukudluliswa kwesignali okuzinzile kanye nokunciphisa ukuphazamiseka kokubonisa. Inikeza amandla okucindezela okufika ku≥40dB ebhendini engu-87.5-108MHz, ithuthukisa ngempumelelo ukusebenza kokumelana nokuphazamiseka.

Njengomuntu onolwaziUmkhiqizi wesihlungi se-LC, i-Apex kade yagxila kuyoIdizayini yesihlungi se-LC RFfuthi isekela izidingo zamakhasimende zokwenza ngokwezifiso zamabhendi amaningi. Iumkhiqizoinamandla okuthwala angu-50W, izinga lokushisa elisebenzayo elingu -40°C kuya +85°C, ifakwe isixhumi esibonakalayo sohlobo lwe-N, futhi ithobela izindinganiso zemvelo ze-RoHS.

Ngokungeziwe kumamodeli ajwayelekile, siphinde sisekele izixazululo ezahlukahlukene ezenziwe ngokwezifiso futhi sinikeze ezenziwe ngokwezifisoimiklamo yokuhlunga ephezuluukuhlangabezana nezidingo ezikhethekile kusakhiwo, isikhombimsebenzisi kanye nokusebenza kukagesi. Kuyinto ekahleLC isihlungi umkhiqizoisisombululo.
