Achikamura simbainokamura chiratidzo chinouya kuita zviratidzo zviviri (kana kupfuura) zvekubuda. Kana zviri nani, chinoparadzanisa simba chinogona kuonekwa sechisina kurasikirwa, asi mukuita kwese panenge paine kupararira kwesimba. Nekuti inetwork inodzokororwa, chinosanganisa simba chinogonawo kushandiswa sechinobatanidza simba, uko maport maviri (kana kupfuura) anoshandiswa kubatanidza zviratidzo zvekupinda muchinhu chimwe chete chinobuda. Mupfungwa, chinoparadzanisa simba nechinhu chinosanganisa simba zvinogona kuva chinhu chimwe chete, asi mukuita kwese panogona kunge paine zvinodiwa zvakasiyana zvevanobatanidza nevanoparadzanisa, zvakaita sekubata simba, kufananidza phase, kufananidza port uye isolation.

Zvikamu zvemagetsi zvinopatsanura magetsi nezvinosanganisa magetsi zvinowanzonzi zvinopatsanura magetsi. Kunyange zvazvo izvi zvakarurama, mainjiniya vanowanzo chengeta izwi rekuti "splitter" kureva chimiro chisingadhuri chinoparadzanisa simba pamusoro pebandwidth yakakura, asi chine kurasikirwa kukuru uye simba shoma.

Izwi rekuti "divider" rinonyanya kushandiswa kana chiratidzo chinouya chikakamurwa zvakaenzana pazvose zvinobuda. Semuenzaniso, kana paine maport maviri ekubuditsa, chimwe nechimwe chinowana zvishoma pasi pehafu yechiratidzo chekupinza, zvakanaka -3 dB zvichienzaniswa nechiratidzo chekupinza. Kana paine maport mana ekubuditsa, chiteshi chimwe nechimwe chinowana chikamu chimwe muzvina chechiratidzo, kana -6 dB zvichienzaniswa nechiratidzo chekupinza.

Kuiswa kwemurwere kwake ega

Pakusarudza rudzi rwemuchina wekuparadzanisa kana wekusanganisa, zvakakosha kufunga nezvekupatsanura. Kupatsanura kwakanyanya zvinoreva kuti zviratidzo zvezviitiko (mumuchina wekusanganisa) hazvipindirani, uye chero simba risingatumirwe kumuchina rinonyangarika pane kutumirwa kumuchina wekuburitsa. Mhando dzakasiyana dzemuchina wekuparadzanisa dzinobata izvi nenzira dzakasiyana. Semuenzaniso, mumuchina wekuparadzanisa weWilkinson, resistor ine kukosha kwe2Z0 uye yakasungirirwa pamagetsi anobuda. Mumuchina wekusanganisa wequadrature, muchina wechina une magumo. Kupatsanura hakuparadzi simba kunze kwekunge paine chakaipa chaitika, sekunge imwe amplifier yakundikana kana kuti ma amplifier ane zvikamu zvakasiyana.

Mhando dzeVanoparadzanisa

Kune mhando dzakasiyana-siyana dzezvigadziri kana kuti zvinosanganisa simba. Zvimwe zvacho zvinosanganisira:

Wilkinson power divider

Mugovanisi weWilkinson unopatsanura chiratidzo chekupinda kuita zviratidzo zviviri zvakaenzana zvechikamu chekubuda, kana kubatanidza zviratidzo zviviri zvakaenzana kuita chimwe chakasiyana. Mugovanisi weWilkinson unovimba nematransformer ekota-wave kuti aenderane nechiteshi chakapatsanurwa. Resistor inoiswa pakati pezvinobuda, uko isingakuvadzi chiratidzo chekupinda paPort 1. Izvi zvinovandudza zvakanyanya kupatsanurwa uye zvinobvumira maport ese kuti aenderane ne impedance. Rudzi urwu rwemugovanisi runowanzo shandiswa mumasystem eredhiyo akawanda nekuti runogona kupa huwandu hwakanyanya hwekupatsanurwa pakati pemaports ekubuda. Nekukanda zvikamu zvakawanda zvekota-wave, Wilkinson's inogona kubata zviri nyore 9:1 bandwidths yemasystem ehondo emagetsi.

Sezvinoreva zita racho, RF/microwave power divider ichapatsanura chiratidzo chekupinda kuita zviratidzo zviviri zvakafanana uye zvakafanana (kureva muchikamu). Inogona zvakare kushandiswa se power combiner, uko common port iri output uye power ports mbiri dzakaenzana dzinoshandiswa se inputs. Zvimiro zvakakosha pazvinoshandiswa se power divider zvinosanganisira insertion loss, amplitude uye phase balance pakati pemaoko, uye return loss. Pakubatanidza simba rezviratidzo zvisina hukama, chinonyanya kukosha i isolation, inova insertion loss kubva kune imwe power port yakaenzana kuenda kune imwe.

Zvinoparadzanisa SimbaZvinhu zvirimo

• Zvinoparadzanisa simba zvinogona kushandiswa sezvinobatanidza kana kupatsanura

• Wilkinson neHigh isolation power dividers dzinopa high isolation, dzinovhara masaini ekutaurirana pakati pe output ports

• Kuisa zvishoma uye kurasikirwa kwekudzoka

• Wilkinson nezvinoparadzanisa simba zvinopa amplitude yakanaka kwazvo (<0.5dB) uye (<3°) phase balance

Si Chuan Keenlion Microwave ine ma "two-way power dividers" akasiyana-siyana mu "narrowband" uye "broadband configurations", inofukidza mafrequency kubva kuDC kusvika ku50 GHz. Yakagadzirwa kuti ikwanise kubata simba rekupinda re10 kusvika ku30 watts mu "50-ohm transmission system". Madhizaini e "microstrip" kana "stripline" anoshandiswa, uye akagadzirirwa kushanda zvakanaka.

Zvishandiso zvinouya zvakajairwa zvine zvibatiso zvechikadzi zveSMA kana N, kana kuti zvibatiso zve 2.92mm, 2.40mm, uye 1.85mm zvezvikamu zve high frequency.

Tinogonawo kugadzirisa chinoparadzanisa simba zvinoenderana nezvamunoda. Munogona kupinda papeji rekugadzirisa kuti mupe zvinodiwa zvamunoda.
