Chodulira cha microwave cha RFndi chipangizo chokhala ndi madoko atatu chomwe chimagwiritsidwa ntchito kutumiza ndikulandira ma RF signals pogwiritsa ntchito antenna yomweyo mumakina olumikizirana. Duplexer imagwira ntchito ngati circulator ya mapulogalamu otsika mphamvu. Mu zida zopanda zingwe monga mafoni anzeru ndi ma LAN opanda zingwe, duplexer yomwe imagwiritsidwa ntchito mu zida ziwiri ndi duplexer yokhala ndi madoko atatu yomwe ili kumapeto kwa mbali ya antenna, yomwe imagwiritsidwa ntchito kulekanitsa magulu awiri a gulu lachiwiri. Zinthu zingapo zofunika ndi izi:
1. Kutayika kwa chizindikiro cha RF pakati pa chotumizira ndi antenna mu chigamba chotumizira ndikochepa, ndipo kutayika pakati pa antenna ndi wolandila munjira yolandirira ndikochepa.
2. Kutalikirana kwakukulu kwa zizindikiro za RF pakati pa chotumizira ndi cholandirira.
Duplexerkapangidwe lingaliro:
1. Duplexer imagwiritsidwa ntchito mu gawo lolowera ndi kutulutsa la antenna, ndipo ili ndi ntchito yogawa kapena kusakaniza ma frequency awiri osiyanasiyana panthawi yotumizira ndi kulandira. RF duplexer ndi chipangizo chotumizira ma signal awiriawiri panjira imodzi. Mu makina olumikizirana pa wailesi kapena radar, ma duplexer amalola kuti agawane antenna yofanana pamene akulekanitsa wolandila ndi wotumiza.
Ma diplexer a microwave a 2.RF opangidwa ndi ma microwave osagwiritsidwa ntchito amatha kupangidwa pogwiritsa ntchito zinthu za cell kapena zinthu zazing'ono zozungulira.
3. Kapangidwe ka Duplexer pogwiritsa ntchito zigawo zapakati: Mu kapangidwe kake, zigawo zosagwiritsidwa ntchito zimagwiritsidwa ntchito popanga zosefera za band-pass, low-pass ndi high pass za duplexer. Duplexer imapangidwa pogwiritsa ntchito zosefera ziwiri za band zomwe zimakhala ndi mayankho osiyanasiyana afupipafupi koma zimakhala ndi mawonekedwe ofanana panjira zolandirira ndi zotumizira. Malingaliro a kapangidwe ka zosefera monga Chebyshev angagwiritsidwe ntchito popatukana bwino pakati pa njira za Tx ndi Rx za ma circuits oyambira.
Zindikirani kuduplexer:
1. Popeza imagwiritsidwa ntchito mu gulu la ma frequency lomwe limagwiritsidwa ntchito ndi wolandila ndi wotumiza, liyenera kukhala lotha kuthana ndi mphamvu yotulutsa ya wotumiza.
2. Phokoso la transmitter lomwe limachitika pafupipafupi polandila liyenera kuchepetsedwa mokwanira ndipo liyenera kupangidwa kuti ligwire ntchito pakati pa transmitter ndi receiver kapena pansi pa nthawi ya pafupipafupi.
3.Kupatula kokwanira kungaperekedwe kuti kupewe kufooka kwa chidziwitso cha wolandirayo.

Si Chuan Keenlion Microwave ndi ma RF Duplexer ambiri omwe ali ndi ma narrowband ndi ma broadband configurations, omwe amaphimba ma frequency kuyambira 0.5 mpaka 50 GHz. Amapangidwa kuti azitha kugwira mphamvu yolowera ya ma watts 10 mpaka 30 mu makina otumizira ma 50-ohm. Mapangidwe a microstrip kapena stripline amagwiritsidwa ntchito, ndipo amakonzedwa kuti agwire bwino ntchito.
Tikhozanso kusintha RF Duplexer malinga ndi zomwe mukufuna. Mutha kulowa patsamba losinthira kuti mupereke zofunikira zomwe mukufuna.
