VHF Cavity Mafirita

VHF cavity masanganisi zvishandiso zvinoshandiswa muVHF kutepfenyura chiteshi kubatanidza kubuda kweakawanda ma transmitters kuita antenna imwe. Izvi zvinobvumira akawanda ma transmitters kuti ashandiswe kuwana kuvharika kwakafanana nema antenna mashoma uye mune dzimwe nguva, yakakwirira masimba masimba. Nekusanganisa akawanda ma transmitters kuita antenna imwe chete, VHF vatepfenyuri vanogona kuwedzera nzvimbo yavo yekuvhara uye kuderedza huwandu hwema antenna anoshandiswa munhepfenyuro yavo. Izvi zvinogona kukonzera kuchengetwa kwemutengo sezvo mashoma antenna anoda kuiswa uye kuchengetedzwa. Pamusoro pazvo, inobvumira vatepfenyuri kuti vape ruzivo rwakanyanya kuvimbika munzvimbo dzisingagoneke nemuchina mumwe chete.

Maitiro ekushandisa nemazvo VHF cavity sefa munhepfenyuro?
1. Sarudza sefa yakakodzera zvichienderana neinodiwa frequency renji uye simba rinodiwa.

VHF cavity sefa inoshanda sei muVHF nhepfenyuro?
Iyo VHF cavity sefa inoshanda nekuteya zvisingadiwe frequency pakati pemaviri kana anopfuura akatuniwa resonant cavities. Iwo ma cavities akabatanidzwa pamwechete kuti agadzire sefa ine chaiyo bandwidth. Sezvo frequency ichipfuura nepasefa, chiratidzo chisingadiwe chinodzikisirwa, chichibvumira chete chiratidzo chaunoda kupfuura. Kuwanda kwekudzikisa kunotarirwa nemhando yehutano (Q) yemakumbo, iyo inogona kugadziriswa nekushandura ukuru hwemukati wemukati. Iyo sefa inoramba chero masaini kunze kweinodiwa frequency renji, ichibvumira iyo inodiwa kuti ipfuure nekukanganisa kudiki.
Nzira yekusarudza yakanakisa VHF cavity sefa?
Paunenge uchisarudza VHF cavity sefa yenhepfenyuro, zvakakosha kuti utarise zvinhu zvakati wandei, kusanganisira yaunoda frequency renji, simba rinodiwa, uye bhajeti. Izvo zvakakoshawo kuve nechokwadi chekuti sefa yakanyatso kuisirwa uye kuyedzerwa kwakakodzera yekuisa kurasikirwa uye frequency mhinduro. Uyezve, zvakakosha kutarisa sefa kune chero zviratidzo zvekuora kana kukuvara. Chekupedzisira, zvakakosha kuve nechokwadi chekuti chiyero chesimba chesefa hachipfuurire uye kuti sefa inokodzera nharaunda iyo ichashandiswa.
Nei VHF cavity sefa yakakosha uye zvichidikanwa kune VHF nhepfenyuro nhepfenyuro?
VHF cavity mafirita akakosha kuVHF nhepfenyuro nekuti anodzivirira siginecha yekutepfenyura kubva mukukanganiswa. Izvi zvinodikanwa kuve nechokwadi chekuti chiratidzo chaunoda chakajeka uye kuti chero ma frequency asingadiwe akavharwa. Nekusefa aya ma frequency asingadiwe, chiratidzo chinodzivirirwa kubva pakukanganiswa uye kukanganisa, zvichipa ruzivo rwekuteerera zviri nani. Pamusoro pezvo, kushandisa VHF cavity sefa kunogona kuderedza simba rinodiwa kutepfenyura, kuchengetedza mari uye kuderedza huwandu hwesimba rinoshandiswa.
Mangani marudzi eVHF cavity sefa aripo?
Kune akati wandei marudzi eVHF cavity mafirita, anosanganisira bandpass mafirita, notch mafirita, lowpass mafirita, uye highpass mafirita. Bandpass mafirita anobvumira kuti yakati frequency renji ipfuure, nepo notch mafirita achiramba imwe frequency. Mafirita eLowpass anobvumira kuti mafrequency ese pazasi peimwe nzvimbo apfuure, nepo mafirita epamusoro achibvumira kuti ma frequency ese ari pamusoro peimwe nzvimbo apfuure. Rudzi rwese rwesefa runopa akasiyana mazinga ekudzivirira uye anogona kushandiswa mumamiriro akasiyana zvichienderana neinodiwa frequency renji uye simba rinodiwa.
Maitiro ekubatanidza nemazvo VHF cavity sefa muVHF nhepfenyuro?
Kuti ubatanidze nemazvo VHF cavity sefa muVHF nhepfenyuro, iyo sefa inofanirwa kuiswa padhuze nemupepeti sezvinobvira. Iyo sefa inofanirwa kuve yakabatana mumutsetse wekutumira pakati peiyo transmitter uye antenna. Sefa inofanirwa kuongororwa kuti yarasika here yekuisa uye frequency mhinduro isati yashandiswa. Pamusoro pezvo, chiyero chesimba chesefa hachifanirwe kudarika uye sefa inofanirwa kutariswa kune chero zviratidzo zvekuipa kana kukuvara.
Ndezvipi zvishandiso zvine chekuita neVHF cavity sefa mune nhepfenyuro?
Midziyo ine hukama neVHF cavity sefa muchiteshi chekutepfenyura inosanganisira iyo sefa pachayo, inofambisa, uye antenna.

Pamusoro pezvo, mita yemagetsi uye frequency analyzer inogona kuve yakakosha pakuyedza sefa yekurasika kwakaringana yekuisa uye frequency mhinduro.
Ndeapi akanyanya kukosha zvirevo zveVHF cavity sefa?
Iwo akanyanya kukosha emuviri uye RF maratidziro eVHF cavity sefa ndiyo frequency renji, kurasikirwa kwekuisa, chiyero chesimba, uye Q factor. Iyo frequency renji inosarudza kuti ndeapi mafrequency anogona kupfuura nepasefa, nepo kurasikirwa kwekuisa kuri kuwanda kwechiratidzo chekudzivirira iyo sefa inopa. Chiyero chesimba chinotaridza kuti isimba rakawanda sei iro sefa rinogona kubata pasina kukuvara, uye iyo Q factor inosarudza huwandu hwekudzikisira pane yakapihwa frequency.
Seinjiniya, sei kuchengetedza VHF cavity sefa muVHF nhepfenyuro?
Seinjiniya, zvakakosha kuchengetedza nemazvo VHF cavity sefa muVHF nhepfenyuro. Izvi zvinosanganisira kutarisa sefa kune chero zviratidzo zvekuipa kana kukuvadzwa, pamwe nekuyedza sefa yekurasika kwakaringana yekuisa uye frequency mhinduro. Pamusoro pezvo, zvakakosha kuve nechokwadi chekuti chiyero chesimba chesefa hachipfuurire uye kuti sefa inokodzera nharaunda iyo ichashandiswa. Kana paine matambudziko akaonekwa, iyo sefa inofanirwa kutsiviwa nekukurumidza sezvinobvira.
Maitiro ekugadzirisa VHF cavity sefa kana ikatadza kushanda muVHF nhepfenyuro?
Kana VHF cavity sefa ikatadza kushanda muVHF nhepfenyuro, inofanirwa kuongororwa kuti ione chikonzero chekutadza. Zvichienderana nechikonzero, sefa inogona kuda kugadziriswa kana kutsiviwa. Kana iyo sefa inogona kugadziriswa, zvikamu zvakaputsika zvinofanirwa kubviswa uye kutsiviwa nezvikamu zvitsva zvinosangana nezvinodiwa zvepakutanga. Kana iyo sefa isingagone kugadziriswa, sefa nyowani inofanirwa kutengwa uye kuiswa mutsetse wekutumira.
Maitiro ekusarudza kurongedza kwakaringana kweVHF cavity sefa panguva yekufambisa?
Pakusarudza kurongedza kwakakodzera kweVHF cavity sefa yeVHF nhepfenyuro, zvakakosha kuti titarise saizi uye huremu hwesefa, pamwe nenharaunda iyo ichachengetwa uye kutakurwa. Iko kurongedza kunofanirwa kuve kwakasimba zvakakwana kuchengetedza sefa kubva mukukuvadzwa, uye inofanirwa kugadzirwa kuchengetedza sefa yakaoma uye isina guruva nemarara. Pamusoro pezvo, iyo sefa inofanirwa kuchengetedzwa mupakeji kudzivirira kufamba panguva yekufambisa, uye pasuru yacho inofanirwa kunyorwa nemazvo kuti ive nechokwadi chekuti inobatwa nemazvo.
Imhandoi yezvinhu iyo casing yeVHF cavity sefa inowanzo gadzirwa?
Iyo casing yeVHF cavity sefa inowanzogadzirwa nesimbi, senge aluminium kana simbi. Izvi zvinhu zvinosarudzirwa simba razvo, kusimba, uye kugona kuvharidzira kukanganiswa kwemagetsi. Izvo zvinhu zvecasing hazvizokanganisa kushanda kwesefa, chero bedzi yakanyatsovharwa.
Chii chakakosha chimiro cheVHF cavity sefa?
Iyo yakakosha chimiro cheVHF cavity sefa ine maviri kana anopfuura akatuniwa resonant cavities akabatanidzwa pamwechete. Iwo cavities akagadzirirwa kuteya zvisingadiwe ma frequency, achibvumira iyo inodiwa chiratidzo kuti ipfuure. Saizi yemukati megoti inotaridza mhando yemhando (Q) yesefa, iyo inotaridza huwandu hwekudzikisira pane yakapihwa frequency. Iyo Q factor ndiyo inonyanya kukosha pakuona kushanda kwesefa, uye iyo sefa haishande sezvaitarisirwa kana chero magonhi akashaikwa kana asina kunyatsogadziriswa.
Muchiteshi chenhepfenyuro, ndiani anofanirwa kupihwa kubata VHF cavity sefa?
Muchiteshi chekutepfenyura, iyo VHF cavity sefa inofanirwa kutungamirwa neinjiniya ane hunyanzvi anoziva sefa uye zvinodiwa pakugadzirisa. Uyu munhu anofanirwa kuve nehunyanzvi hwekutaurirana, pamwe neruzivo rwehunyanzvi uye ruzivo mukushanda nekuchengetedza VHF cavity mafirita. Pamusoro pezvo, vanofanirwa kuve nekwaniso yekuziva chero zviratidzo zvekuipa kana kukuvadzwa, uye vakwanise kugadzirisa nekugadzirisa sefa kana zvichidikanwa.
