Ham radio operators vanogara vachitsvaga michina yakanaka yekuvandudza mashandiro avo. Kana zvasvika pakumisikidza chiteshi chinodzokorora, pane akati wandei ekufunga nezvawo, zvinosanganisira antennas, amplifiers, uye mafirita. Chimwe chezvakanyanya kukosha ndeye duplexer kana cavity sefa, iyo inoita basa rakakosha mukugadzirisa mafambiro eredhiyo, kunyanya munzvimbo dzine vanhu vakawanda. Muchinyorwa chino, isu tichaongorora mabhenefiti uye mashandisiro eUHF duplexers uye mafirita emhangura e ham radio.
UHFDuplexeruyeCavity SefaOverview
Iyo duplexer kana cavity sefa chishandiso chinoshandisa parallel resonant maseketi kubvumira antenna imwe chete kushandiswa kugamuchira uye kutumira masaini pama frequency akasiyana. Inoshanda nekuparadzanisa masaini anouya uye anobuda mumigwagwa miviri yakaparadzana, achivabvumira kupfuura panguva imwe chete kuburikidza neantenna imwechete pasina kukanganisa mumwe nemumwe. Pasina gavi sefa kana duplexer, chiteshi chinodzokorora chaizoda maviri akapatsanurwa antenna, imwe yekufambisa uye imwe yekugamuchira. Iyi mhinduro haisi nguva dzose inoshanda kana inogoneka, kunyanya munzvimbo dzemaguta umo nzvimbo inogumira.
UHF duplexers uye mafirita emhangura akagadzirirwa kubata huwandu hwakafara hwema frequency, kazhinji pakati pe400 MHz uye 1 GHz, zvichiita kuti ive sarudzo yakanaka kwazvo yeredhiyo ham. Vanogona kusefa zviratidzo zvisingadiwi uye kukanganisa, zvichibvumira kutaurirana kwakajeka uye kwakavimbika. Pamusoro pezvo, iwo ari nyore kuisa, compact, uye yakaderera-yekugadzirisa zvishandiso.
Mabhenefiti eUHF Duplexers uye Cavity Filters
Imwe yemabhenefiti makuru ekushandisa UHF duplexer kana cavity sefa kugona kwayo kuwedzera kushanda kweiyo inodzokorora chiteshi. Nekubvumidza antenna imwe chete kubata akawanda ma frequency, inoderedza huwandu hwenzvimbo inodiwa uye inorerutsa maitiro ekuseta. Iyo inovandudzawo huwandu hwechiratidzo chemhando, kuderedza ruzha uye kukanganisa, izvo zvinogona kukonzera kutaurirana kwakavimbika.
Imwe mukana ndeyekuti UHF duplexers uye cavity mafirita anogona kubatsira kuchengetedza zviri pamutemo frequency kushandiswa. Kushandisa maredhiyo enzira mbiri pasina kusefa kwakakwana kunogona kukonzera kukanganisa nemimwe michina yekutaurirana, izvo zvinogona kukonzera kukanganisa kumabasa ekukurumidzira. Vashandi vezvekutengeserana nevemaindasitiri vanosungirwa kushandisa mafirita kuona kuti havasi kutyora chero mitemo ine chekuita nekukanganiswa kweredhiyo.
Zvikumbiro zveUHFDuplexersuyeCavity Filters
UHF duplexers uye mafirita mafirita anogona kushandiswa mumhando dzakasiyana dzekushandisa, kusanganisira nharembozha, base zviteshi, uye zviteshi zvinodzokorora. Mune nharembozha, dzinogona kushandiswa kusefa kunze zvisingadiwe masaini uye kugadzirisa chiratidzo chechiratidzo paunenge uchifamba. Muzviteshi zvepasi, ivo vanogona kubatsira kubata akawanda mafrequency uye kugadzirisa kuvharika kwese. Muzviteshi zvekudzokorodza, zvakakosha pakubvumira antenna imwe chete kubata ese ari maviri ekutepfenyura nekugamuchira masaini, achivaita iwo anofanirwa kuve nawo kune vanofarira radio radio.
Mhedziso
UHF duplexers uye mafirita mafirita maturusi akakosha kune ham radio operators, achivabvumira kubata akawanda mafrequency uye kuvandudza kushanda kwese kweseta yavo. Iwo ari nyore kuisa, yakaderera-kugadzirisa, uye inopa huwandu hwemashandisirwo munharembozha, base zviteshi, uye zviteshi zvinodzokorora. Kana zvasvika pakumisikidza yakavimbika yekutaurirana network, yakanaka sefa ndiyo inofanirwa kuve nayo. Kunyangwe iwe uri hobbyist kana nyanzvi, uchishandisa UHF duplexer kana cavity sefa ndiyo nzira yakanakisa yekuve nechokwadi chekutaura kwakajeka uye kwakavimbika pasina kukanganisa kana kukanganisa.
Si Chuan Keenlion Microwave sarudzo yakakura mune narrowband uye Broadband masisitimu, inovhara ma frequency kubva 0.5 kusvika 50 GHz. Iwo akagadzirirwa kubata kubva pagumi kusvika pamakumi matatu ekuisa simba mu50-ohm transmission system. Microstrip kana stripline madhizaini anoshandiswa, uye akakwenenzverwa kuita zvakanaka.
