Zozungulira za RF ndi zida zongokhala ndi madoko atatu kapena kupitilira apo zomwe zimatha kutumiza ma siginecha a RF mbali imodzi. Ntchito yake yaikulu ndikuwongolera kayendedwe ka kayendedwe ka chizindikiro, kuonetsetsa kuti chizindikirocho chikalowa kuchokera ku doko limodzi, chimachokera ku doko lotsatira, ndipo sichidzabwerera kapena kutumizidwa ku madoko ena. Izi zimapangitsa kuti zozungulira zizigwiritsidwa ntchito kwambiri pamakina osiyanasiyana a RF ndi ma microwave.
Ntchito zazikulu za RF zozungulira:
Duplexer ntchito:
Zochitika pakugwiritsa ntchito: M'makina a radar kapena makina olumikizirana opanda zingwe, chotumizira ndi cholandila nthawi zambiri amagawana mlongoti wamba.
Njira yogwiritsira ntchito: Lumikizani transmitter ku doko 1 la circulator, antenna ku doko 2, ndi wolandira ku doko 3. Mwanjira iyi, chizindikiro chotumizira chimaperekedwa kuchokera ku doko 1 kupita ku doko 2 (mlongoti), ndipo chizindikiro cholandira ndi kutumizidwa kuchokera ku doko 2 kupita ku doko 3 (wolandira), pozindikira kudzipatula kwa kufalitsa ndi kulandira kuti apewe kusokonezana.
Isolator ntchito:
Zochitika pakugwiritsa ntchito: Amagwiritsidwa ntchito kuteteza zida zazikulu zamakina a RF, monga zokulitsa mphamvu, ku zowonongeka zomwe zimayambitsidwa ndi ma siginecha.
Kukonzekera: Lumikizani transmitter ku doko 1 la circulator, mlongoti ku doko 2, ndi katundu wofanana ndi doko 3. Muzochitika zachilendo, chizindikirocho chimaperekedwa kuchokera ku doko 1 kupita ku doko 2 (mlongoti). Ngati pali kusagwirizana kwa mlongoti kumapeto kwa mlongoti, zomwe zimabweretsa kuwonetsera kwa siginecha, chizindikiro chowonetsedwacho chimatumizidwa kuchokera ku doko 2 kupita kumalo ofananirako a doko 3 ndikuyamwa, potero kuteteza chotumizira ku chikoka cha siginecha yowonetsedwa.
Reflection amplifier:
Momwe mungagwiritsire ntchito: M'makina ena a microwave, ndikofunikira kuwonetsa chizindikiro kumbuyo komwe kumachokera kuti mukwaniritse ntchito zina.
Kukhazikitsa: Pogwiritsa ntchito njira zotumizira zozungulira, chizindikiro cholowera chimalunjikitsidwa ku doko linalake, ndipo pambuyo pokonza kapena kukulitsa, chimawonetsedwanso ku gwero kudzera pa circulator kuti akwaniritse zobwezeretsanso chizindikiro.
Kugwiritsa ntchito pamagulu a antenna:
Momwe mungagwiritsire ntchito: M'magulu a antenna (AESA) omwe amagwira ntchito, ma siginecha amayunitsi angapo amayenera kuyang'aniridwa bwino.
Kukhazikitsa: Chozungulira chimagwiritsidwa ntchito pagawo lililonse la mlongoti kuti zitsimikizire kudzipatula koyenera kwa kutumiza ndikulandila ma siginecha ndikuwongolera magwiridwe antchito ndi kudalirika kwa gulu la antenna.
Kuyeza ndi kuyeza kwa labotale:
Momwe mungagwiritsire ntchito: M'malo oyeserera a RF, zida zodziwikiratu zimatetezedwa ku chikoka cha ma siginecha.
Kukhazikitsa: Ikani chozungulira pakati pa gwero la siginecha ndi chipangizo chomwe chikuyesedwa kuti mutsimikizire kutumizidwa kwa siginecha kumodzi ndikuletsa ma siginecha owonetseredwa kuti asawononge gwero la siginecha kapena kukhudza zotsatira zake.
Ubwino wa RF circulators:
Kudzipatula kwakukulu: Phatikizani bwino zizindikiro pakati pa madoko osiyanasiyana kuti muchepetse kusokoneza.
Kutayika kwapang'onopang'ono: Onetsetsani kuti ntchito ndi khalidwe la kutumizira zizindikiro.
Wide bandwidth: Imagwira pamagawo osiyanasiyana osiyanasiyana kuti ikwaniritse zofunikira zosiyanasiyana.
Ndi chitukuko chofulumira chaukadaulo wamalumikizidwe opanda zingwe, zozungulira za RF zimagwira ntchito yofunika kwambiri pamakina amakono olankhulirana. Kugwiritsa ntchito kwake pakulankhulana kwapawiri, kudzipatula kwazizindikiro ndi machitidwe a mlongoti kwathandizira kwambiri magwiridwe antchito komanso kudalirika kwadongosolo. M'tsogolomu, ndikupita patsogolo kwaukadaulo, magawo ogwiritsira ntchito ndi ntchito za ma RF ozungulira azikhala ochulukirapo komanso osiyanasiyana.
