Isihlungi se-LC High-Pass: Isixazululo se-RF Esisebenza Kakhulu se-118-138MHz Band

faka isizinda sokuthuthukiswa okuqhubekayo kwezokuxhumana okungenantambo kanye nezinhlelo ze-RF,Izihlungi ze-LC ezidlula kakhuluzisetshenziswa kabanzi ezinhlelweni ezahlukene ze-VHF RF ngenxa yesakhiwo sazo esincane, ukusebenza okuzinzile, kanye nokuphendula okuguquguqukayo. Imodeli ye-ALCF118M138M45N eyethulwe yi-Apex Microwave iyisibonelo esijwayelekile, eyenzelwe ibhendi engu-118MHz kuya ku-138MHz, kucatshangelwa kokubili ukusebenza kanye nokuthembeka.

Lokhuumkhiqizoiyisihlungi se-FM esakhiwe ngokuzimela yi-Apex, esingacindezela ngempumelelo izinhlelo zokusakaza umsakazo we-FM ebangeni lama-87-108MHz, ngenkathi sidlula ngempumelelo isignali eqondiwe engu-118-138MHz ebhendini le-VHF, okunganciphisa izimpawu ezilahlekile futhi kugweme ukuphazamiseka kohlelo.

IIsihlungi se-LC esidlula phezului-r inokulahlekelwa okuphansi kokufakwa kwe-≤I-1.0dB kanye nokulahlekelwa okuphezulu kokubuya kwe-≥I-15dB, iqinisekisa ukudluliswa kwesignali okuzinzile kanye nokunciphisa ukuphazamiseka kokukhanya. Inikeza amandla okucindezela afinyelela ku-≥40dB kubhendi engu-87.5-108MHz, okuthuthukisa ngempumelelo ukusebenza kohlelo lokulwa nokuphazamiseka.

Njengomuntu onolwaziUmkhiqizi wesihlungi se-LC, I-Apex ibilokhu igxile kakhuluUmklamo wesihlungi se-LC RFfuthi isekela izidingo zamakhasimende zokwenza ngokwezifiso amabhendi amaningi.umkhiqizoinomthamo wokuthwala amandla ongu-50W, ububanzi bokushisa bokusebenza obungu--40°C kuya ku-+85°I-C, ifakwe isikhombimsebenzisi sohlobo lwe-N, futhi ihambisana nezindinganiso zemvelo ze-RoHS.

Ngaphezu kwamamodeli ajwayelekile, sisekela nezixazululo ezahlukahlukene ezenziwe ngokwezifiso futhi sihlinzeka ngezifisoimiklamo yokuhlunga ephezuluukuhlangabezana nezidingo ezikhethekile zesakhiwo, isikhombimsebenzisi kanye nokusebenza kukagesi. Kuyindlela ekahle kakhuluUmkhiqizo wokuhlunga we-LCikhambi.
