• Pogawa chizindikiro m'magulu awiri a matalikidwe ofanana ndi kusiyana kwa 90 ° kapena 180 ° nthawi zonse.
• Kuphatikizika kwa ma quadrature kapena kupanga kuphatikiza / kuphatikizika kosiyana.
Mawu Oyamba
Ma hybrids ndi ma hybrids ndi zida zomwe mizere iwiri yopatsirana imadutsana moyandikirana kuti mphamvu imafalikire pamzere umodzi kupita ku mzere wina. A 3dB 90 ° kapena 180 ° wosakanizidwa amagawa chizindikiro cholowetsa muzotulutsa ziwiri zofanana za matalikidwe. Ma coupler otsogolera nthawi zambiri amagawa chizindikiro cholowera muzotulutsa ziwiri zosagwirizana. Mawu akuti “directional coupler”, “90° hybrid”, ndi “180° hybrid” amachokera pamisonkhano. Komabe, ma hybrids a 90 ° ndi 180 ° amatha kuganiziridwa ngati ma 3 dB owongolera. Ngakhale izi zikufanana, magawo omwe amagwiritsidwa ntchito pofotokozera mayendedwe azizindikiro mu ma couplers olunjika ndi kugwiritsa ntchito, m'magwiritsidwe enieni, ndi osiyana mokwanira kuti apereke malingaliro osiyana.
180 ° Hybrids Kufotokozera Kwantchito
Chosakanizidwa cha 180 ° ndi chipangizo chofanana cha madoko anayi chomwe chimapereka zizindikiro ziwiri zofanana za matalikidwe mugawo pamene zimadyetsedwa kuchokera ku doko lake (S) ndi zizindikiro ziwiri zofanana za 180 ° kunja kwa gawo pamene zimadyetsedwa kuchokera ku doko lake losiyana (D). Mosiyana ndi izi, ma siginecha amalowetsa madoko C ndi D adzawonjezera pa doko lachiwerengero (B) ndipo kusiyana kwa ma siginecha awiriwo kudzawonekera pa doko losiyana (A). Chithunzi 1 ndi chithunzi chomwe chidzagwiritsidwa ntchito m'nkhaniyi kuyimira 180 ° wosakanizidwa. Port B imatha kuonedwa ngati doko lalikulu komanso doko A ndiye doko losiyana. Madoko A ndi B ndi madoko C ndi D ndi awiriawiri a madoko.
90 ° Hybrid kapena ma hybrid couplers kwenikweni ndi 3 dB otsogolera ma coupler momwe gawo la chizindikiro chophatikizika ndi chizindikiro chotuluka ndi 90 ° motalikirana. Popeza -3 dB imayimira theka la mphamvu, 3 dB coupler imagawa mphamvu mofanana (mkati mwa kulolerana kwina) pakati pa zotuluka ndi madoko ophatikizidwa. Kusiyana kwa gawo la 90 ° pakati pa zotuluka kumapangitsa kuti ma hybrids akhale othandiza pakupanga ma attenuators amagetsi, zosakaniza za ma microwave, ma modulator ndi zida zina zambiri za ma microwave. Chithunzi 5 chikuwonetsa chithunzi chozungulira ndi tebulo lachowonadi lomwe lidzagwiritsidwe ntchito pofotokozera za hybrid ya RF frequency 90°. Monga momwe tikuwonera mu chithunzichi, chizindikiro chomwe chimagwiritsidwa ntchito pazolowera zilizonse chimapangitsa kuti zizindikilo ziwiri zofanana za matalikidwe omwe ali quadrature, kapena 90 °, achoke pagawo wina ndi mnzake. Madoko A ndi B ndi Madoko C ndi D ali kwaokha. Monga tanenera kale mu gawo la 180 ° hybrid, zida za RF ndi ma microwave zimagwiritsa ntchito njira zosiyanasiyana zomangira. Ngakhale mayankho amalingaliro ndi ofanana, malo adoko ndi msonkhano ndi wosiyana. Pansipa, pazithunzi pali mitundu ya "kuwoloka" ndi "non-crossover" yoperekedwa ma frequency a microwave (500 MHz ndi mmwamba) ndi tebulo lachowonadi. Ma hybrids a digiri makumi asanu ndi anayi amatchedwanso ma quadrature hybrids chifukwa gawo la zotuluka ziwirizi ndi quadrant (90°) motalikirana. Zindikiraninso kuti sizipanga kusiyana kulikonse komwe ndi doko lolowera malinga ngati ubale pakati pa madoko ukhalabe. Izi zili choncho chifukwa ma 90° hybrids ndi magetsi komanso makina ofananira ma X ndi Y Axes.
Si Chuan Keenlion Microwave kusankha kwakukulu kwa mlatho wosakanizidwa wa 3DB mumipangidwe yopapatiza ndi ma burodibandi, kuphimba ma frequency kuchokera ku 0.5 mpaka 50 GHz. Amapangidwa kuti azigwira kuchokera pa 10 mpaka 30 watts kulowetsa mphamvu mu 50-ohm transmission system. Mapangidwe a Microstrip kapena stripline amagwiritsidwa ntchito, ndikukonzedwa kuti azigwira bwino ntchito.
Mayunitsi amabwera muyezo wokhala ndi zolumikizira za SMA kapena N zazikazi, kapena 2.92mm, 2.40mm, ndi zolumikizira za 1.85mm pazigawo zapamwamba kwambiri.
Titha kusinthanso 3DB Hybrid Bridge malinga ndi zomwe mukufuna. Mutha kulowa patsamba losintha kuti mupereke zomwe mukufuna.
