Izindaba - I-Helical Duplexer Yokuxhumana kwe-VHF/UHF

Amabhendi emvamisa ye-VHF/UHF ayaqhubeka nokudlala indima engenakuphikwa kokubili ekuxhumaneni kwabantu kanye nezimboni.i-duplexer eyisiyingiinezinga lokusebenza kahle kokuhlunga, ukuqina okuqinile kanye nokusebenza kahle kwezindleko, okwenza kube ukukhetha okuphezulu kwezinhlelo zomsakazo, ama-repeater kanye namadivayisi eselula.

Inzuzo eyinhloko yalokhui-duplexer yeselula eyisiyingiilele ekwakhiweni kwesakhiwo sayo esijikelezayo, esihambisana nobude obugcwele¼ λubuchwepheshe bokuzwakala. Lo mklamo uvumela ukulungiswa ngaphakathi Imvamisa engu-150MHz kanye no-380-450MHz ihluka ngenkathi ifinyelela ngaphezu kuka-85 dB wokuhlukaniswa—ukuhlunga ngempumelelo imfuhlumfuhlu kagesi kanye nokunciphisa ukulahlekelwa kokufakwa ngezinga eliphezulu. Ngokwesakhiwo,i-duplexer eyisiyingiinendlu encane ye-aluminium ekhishwe ngaphandle, ehambisana ne-chassis yensimbi engasebenzisi lutho kanye nezingxenye ezifakwe i-Teflon. Ingaphandle layo limbozwe nge-vinyl emnyama engagqwali, okuqinisekisa ukusebenza okuzinzile ngisho nasezindaweni zangaphandle nezimboni ezinzima.

⭐Izimo Ezintathu Zokusebenza Eziyinhloko

1. Ama-Repeater Anamandla Aphansi: Igcina isilinganiso esiphansi se-Voltage Standing Wave Ratio (VSWR) esizinzile ngesikhathi sokusebenza isikhathi eside komthwalo ogcwele, okunciphisa kakhulu ukulahleka kwamandla. Ifaneleka kakhulu ekusetshenzisweni ngaphandle kokunakekelwa ezindaweni ezinezintaba, ngaphansi komhlaba, nakwezinye izindawo, iyasiza ekwandiseni ukumbozwa kokuxhumana.

2. Imisakazo engenantambo yedijithali ne-analog: Ihlanganisa amabhendi emvamisa ye-VHF 150 MHz kanye ne-UHF 380–450 MHz, ivumela ukuhlanganiswa okungenamthungo nemishini evamile ngaphandle kwesidingo sokulungiswa okwengeziwe kwemvamisa. Iqeda ngokuphelele ukukhuluma ngezendlalelo ezindaweni eziyinkimbinkimbi ze-electromagnetic, ihlangabezana nezidingo zokuxhumana kobuchwepheshe kanye nokusetshenziswa komsakazo kwabaqalayo.

3. Iselula Egcwele Amadivayisi e-Duplex: Inesakhiwo esincane, ukumelana nokudlidliza, kanye nokuzivumelanisa nezimo zokushisa, ivumela ukudluliswa kwesignali okubushelelezi nokuvumelanayo. Kuyisici esifanele sokufanisa izimo ezifana nokutakula okuphuthumayo kanye nemisebenzi yasensimini.

Uma kuqhathaniswa nobukhulu be-duplexer yendabuko, lo mkhiqizo ufinyelela ibhalansi ephelele phakathi kokusebenza nokusebenza kahle, ngezinzuzo ezibalulekile ekusebenzeni kahle kwamandla kanye nokusebenza kahle kwezindleko. Ifanele ukuthunyelwa ngezinga elikhulu kumaphrojekthi amancane kanye nokuthuthukiswa kwemishini yobungcweti, inikeza ukwesekwa okuqinile kokuxhumana kwe-VHF/UHF yesizukulwane esilandelayo..

Xhumana nathi ukuze uthole ikhotheshini! Lo mkhiqizo usetshenziswa kabanzi kwezokuphepha komphakathi, ezokuthutha kanye nezokuthutha, ezenzakalelayo zezimboni, kanye nomsakazo wabaqalayo, uthembeke kakhulu emakethe.
