Vashandi veHam radio vanogara vachitsvaga michina yakanakisisa yekuvandudza mashandiro avo. Kana zvasvika pakugadzira repeater station, kune zvinhu zvakawanda zvekufunga nezvazvo, zvinosanganisira antennas, amplifiers, uye filters. Chimwe chezvinhu zvakakosha iduplexer kana cavity filter, iyo inoita basa rakakosha mukugadzirisa mafrequency eredhiyo, kunyanya munzvimbo dzine vanhu vakawanda vanofamba. Muchinyorwa chino, tichaongorora mabhenefiti uye mashandisirwo eUHF duplexers nema cavity filters eham radio.
UHFDuplexeruyeSefa yeCavityPfupiso
Duplexer kana kuti cavity filter mudziyo unoshandisa parallel resonant circuits kuti antenna imwe chete ishandiswe kugamuchira nekutumira masaini pamafrequencies akasiyana. Inoshanda nekuparadzanisa masaini anopinda neanobuda kuita nzira mbiri dzakasiyana, zvichivabvumira kupfuura panguva imwe chete neantenna imwe chete pasina kukanganisana. Pasina cavity filter kana duplexer, repeater station inoda maantenna maviri akasiyana, rimwe rekutumira uye rimwe rekugamuchira. Mhinduro iyi haisi nguva dzose inoshanda kana kuti inogoneka, kunyanya munzvimbo dzemaguta uko nzvimbo iri shoma.
MaUHF duplexers nema cavity filters akagadzirwa kuti ashande ma frequency akasiyana-siyana, anowanzova pakati pe400 MHz ne1 GHz, zvichiita kuti ave sarudzo yakanaka ye ham radio. Anogona kusefa masaini asingadiwe uye kupindira, zvichiita kuti kutaurirana kwakajeka uye kwakavimbika. Pamusoro pezvo, ari nyore kuisa, akamanikana, uye haagadzirisi zvakanyanya.
Mabhenefiti eUHF Duplexers neCavity Filters
Chimwe chezvakanakira zvikuru zvekushandisa UHF duplexer kana cavity filter kugona kwayo kuwedzera kushanda zvakanaka kwerepeater station. Nekubvumira antenna imwe chete kutonga ma frequency akawanda, inoderedza huwandu hwenzvimbo inodiwa uye inoita kuti maitiro ekugadzirisa ave nyore. Inovandudzawo kunaka kwemasaini ese, ichideredza ruzha nekupindira, izvo zvinogona kukonzera kutaurirana kwakavimbika.
Chimwe chakanakira ndechekuti maUHF duplexers nema cavity filters zvinogona kubatsira kuchengetedza kushandiswa kwema frequency zviri pamutemo. Kushandisa maredhiyo maviri pasina kusefa kwakakwana kunogona kukonzera kukanganiswa kwemamwe maturusi ekutaurirana, zvichikonzera kukanganiswa kwemabasa ekukurumidzira. Vashandisi vemabhizinesi nemaindasitiri vanosungirwa kushandisa ma filters kuti vave nechokwadi chekuti havasi kutyora mitemo ine chekuita nekukanganiswa kwema frequency eredhiyo.
Mashandisirwo eUHFDuplexersuyeMafirita Emumaburi
MaUHF duplexers nema cavity filters zvinogona kushandiswa mumhando dzakasiyana-siyana dzemashandisirwo, kusanganisira ma mobile units, base stations, uye repeater stations. Mu mobile units, dzinogona kushandiswa kusefa masignal asingadiwe uye kuvandudza kunaka kwemasignal paunenge uri munzira. Mu base stations, dzinogona kubatsira kugadzirisa ma frequency akawanda uye kuvandudza kufukidzwa kwese. Mu repeater stations, dzinodiwa kuti antenna imwe chete igone kubata masignal ekutumira nekugamuchira, zvichiita kuti ave chinhu chinodiwa kune vanofarira ham radio.
Mhedziso
MaUHF duplexers nema cavity filters zvishandiso zvakakosha kune vanofambisa maradio eham, zvichivabvumira kubata ma frequency akawanda uye kuvandudza kushanda zvakanaka kwese kwese kwese kwese. Zviri nyore kuisa, hazvigadziriswi zvakanyanya, uye zvinopa maapplication akasiyana-siyana mumafoni, ma base stations, uye ma repeater stations. Kana zvasvika pakugadzira network yekutaurirana yakavimbika, firita yakanaka inofanirwa kuve nayo. Ungave uri munhu anofarira zvemitambo kana nyanzvi, kushandisa UHF duplexer kana cavity filter ndiyo nzira yakanakisa yekuona kutaurirana kwakajeka uye kwakavimbika pasina kukanganiswa kana kukanganiswa.
Si Chuan Keenlion Microwave ine sarudzo yakakura mu narrowband uye broadband configurations, inofukidza ma frequency kubva pa 0.5 kusvika 50 GHz. Yakagadzirwa kuti ikwanise kubata simba rekupinda rema watts gumi kusvika makumi matatu mu 50-ohm transmission system. Madhizaini e microstrip kana stripline anoshandiswa, uye akagadzirirwa kushanda zvakanaka.
