The Wilkinson power divider ndi chogawanitsa chokhazikika chomwe chimagwiritsa ntchito ma transmitter awiri, ofanana, osaphatikizana a quarter-wavelength transmission. Kugwiritsa ntchito mizere yopatsira kumapangitsa kuti chogawa cha Wilkinson chikhale chosavuta kugwiritsa ntchito pogwiritsa ntchito mizere yosindikizidwa yosindikizidwa. Kutalika kwa mizere yopatsira nthawi zambiri kumachepetsa ma frequency a Wilkinson divider ku ma frequency opitilira 500 MHz. The resistor pakati pa madoko otuluka amawalola kukhala ndi zopinga zofananira pomwe akupereka kudzipatula. Chifukwa madoko otuluka amakhala ndi ma siginecha a matalikidwe ndi gawo lomwelo, palibe voteji kudutsa resistor, kotero palibe ukuyenda wapano ndipo resistor sichimataya mphamvu iliyonse.
Zogawa mphamvu
Wogawa mphamvu ali ndi chizindikiro chimodzi cholowetsa ndi zizindikiro ziwiri kapena zingapo zotuluka. Zizindikiro zotulutsa zimakhala ndi mulingo wa mphamvu womwe ndi 1/N mulingo wamagetsi olowetsa pomwe N ndi kuchuluka kwa zotuluka mugawo. Zizindikiro pa zotuluka, mu mawonekedwe ofala kwambiri ogawa mphamvu, ali mu gawo. Pali zida zapadera zogawa mphamvu zomwe zimapereka kusintha kosinthika pakati pa zotulutsa. Mapulogalamu amtundu wa RF ogawa mphamvu, monga tanenera kale, amawongolera gwero la RF ku zida zingapo (Chithunzi 1).
Chithunzi cha RF source cholozera ku zida zingapo
Chithunzi 1: Zogawa zamagetsi zimagwiritsidwa ntchito kugawa chizindikiro cha RF wamba kuzipangizo zingapo monga gawo la antenna system kapena mu quadrature demodulator.
Chitsanzo ndi mlongoti wokhazikika pomwe gwero la RF limagawika pakati pa zinthu ziwiri za mlongoti. Antennas amtunduwu amakhala ndi zinthu ziwiri kapena zisanu ndi zitatu kapena kupitilira apo, chilichonse chomwe chimayendetsedwa kuchokera pa doko logawa mphamvu. Zosintha zamagawo nthawi zambiri zimakhala zakunja kwa chogawa kuti zilole kuwongolera kwamagetsi kuwongolera mlongoti wakumunda.
Chogawa mphamvu chikhoza kuyendetsedwa "kumbuyo" kotero kuti zolowetsa zambiri zitha kuphatikizidwa kukhala chinthu chimodzi chopanga chophatikizira mphamvu. Mu makina ophatikizira zida izi zimatha kuwonjezera ma vector kapena kuchotsa ma siginecha kutengera matalikidwe awo ndi magawo ake.
Wogawa MphamvuMawonekedwe
• Zogawa zamagetsi zitha kugwiritsidwa ntchito ngati zophatikizira kapena zogawa
• Wilkinson ndi High kudzipatula mphamvu dividers amapereka kwambiri kudzipatula, kutsekereza chizindikiro kuyankhulana pakati pa madoko zotuluka
• Kuyika kochepa ndi kubwereranso kutaya
• Wilkinson ndi zogawa mphamvu zodzitchinjiriza zimapereka matalikidwe apamwamba kwambiri (<0.5dB) ndi (<3°)
• Mayankho a Multi-octave kuchokera ku DC kupita ku 50 GHz
Dziwani zambiri za Power Dividers
Monga momwe dzinalo limatanthawuzira, chogawa chamagetsi cha RF/microwave chimagawaniza siginecha kukhala ma siginecha awiri ofanana ndi ofanana (mwachitsanzo mu gawo). Itha kugwiritsidwanso ntchito ngati chophatikizira mphamvu, pomwe doko wamba ndilotulutsa ndipo madoko awiri ofanana amagwiritsidwa ntchito ngati zolowetsa. Mafotokozedwe ofunikira akagwiritsidwa ntchito ngati chogawa mphamvu amaphatikizapo kutayika kwa kuika, kubwereranso, ndi matalikidwe ndi gawo lapakati pakati pa mikono. Pakuphatikiza mphamvu zama siginecha osagwirizana, monga poyesa mayeso olondola a intermodulation distortion (IMD) ngati IP2 ndi IP3, chofunikira kwambiri ndikudzipatula pakati pa madoko olowera.
Pali mitundu itatu ikuluikulu ya zogawa mphamvu za RF ndi zophatikizira mphamvu za RF: 0º, 90 hybrid wosakanizidwa, ndi 180º wosakanizidwa. Ogawa zero-degree RF amagawa siginecha yolowera m'masigino awiri kapena kupitilira apo omwe ali ofanana mumtali ndi gawo. Zophatikiza za Zero-degree RF zimalumikizana ndi ma siginecha angapo kuti apereke chotuluka chimodzi. Posankha 0 º dividers, magawo ogawa mphamvu ndi mfundo yofunika kuiganizira. Parameter iyi ndi kuchuluka kwa zotulutsa za chipangizocho, kapena kuchuluka kwa njira zomwe siginecha yolowera imagawika pazotulutsa. Zosankha zikuphatikiza 2, 3, 4, 5, 6, 7, 8, 9, 12, 16, 32, 48, ndi 64-njira zida.
RF magetsi splitters / dividersndi zida za RF / microwave zomwe zimagwiritsidwa ntchito pogawa (kapena kugawa) ma siginecha a microwave. Sichuan Keenlion Microwave Technology CO., Ltd zogawa mphamvu zikuphatikiza 2-way, 3-way, 4-way, 6-way, 8-way mpaka 48-way machitidwe a 50 Ohm ndi 75 Ohm machitidwe, okhala ndi DC-passing ndi DC-blocking, mu coaxial, surface mount, ndi MMIC die formats. Zigawo zathu za coaxial zilipo ndi SMA, N-Type, F-Type, BNC, 2.92mm ndi 2.4mm zolumikizira. Sankhani kuchokera pamitundu yopitilira 100 yomwe ili ndi ma frequency osiyanasiyana mpaka 50
GHz, kugwiritsa ntchito mphamvu mpaka 200W, kutaya pang'ono kuyika, kudzipatula kwambiri, komanso kusalinganika bwino kwa matalikidwe ndi gawo losagwirizana.
Tithanso kusintha Sefa ya Band Pass malinga ndi zomwe mukufuna. Mutha kulowa patsamba losintha kuti mupereke zomwe mukufuna.
