Chifukwa Chake Zogawa Mphamvu Sizingagwiritsidwe Ntchito Ngati Zophatikiza Zamphamvu Kwambiri

Zofooka za ogawa mphamvu pakugwiritsa ntchito mphamvu zambiri zitha kuyambitsidwa ndi zinthu zofunika izi:

‌1. Zoletsa Zokhudza Kusamalira Mphamvu za Choletsa Kudzipatula (R)‌

• ‌Njira Yogawa Mphamvu‌:
• Ikagwiritsidwa ntchito ngati chogawa mphamvu, chizindikiro cholowera paINimagawidwa m'magulu awiri a co-frequency, co-phase signals pa mfundo ‌AndiB‌.
• Chotsutsa cha kudzipatulaRSichikumana ndi kusiyana kwa magetsi, zomwe zimapangitsa kuti pasakhale kuyenda kwa magetsi komanso kuti magetsi asatayike. Mphamvu yamagetsi imatsimikiziridwa ndi mphamvu yogwiritsira ntchito mphamvu ya chingwe cha microstrip.
• ‌Njira Yophatikiza‌:
• Ikagwiritsidwa ntchito ngati chophatikiza, zizindikiro ziwiri zodziyimira pawokha (kuchokera kuKUCHOKERA1ndiOUT2ndi ma frequency kapena magawo osiyanasiyana amagwiritsidwa ntchito.
• Kusiyana kwa ma voltage kumachitika pakati paAndiB‌, zomwe zimayambitsa kuyenda kwa magetsi kudzeraRMphamvu zinatha muRzofanana½ (OUT1 + OUT2)Mwachitsanzo, ngati cholowera chilichonse chili 10W,RIyenera kupirira kutentha kwa ≥10W.
• Komabe, choletsa kudzipatula mu magawanidwe amphamvu okhazikika nthawi zambiri chimakhala gawo la mphamvu yochepa lomwe silimatha kutentha mokwanira, zomwe zimapangitsa kuti lizitha kulephera kutentha kwambiri pakakhala mphamvu zambiri.

‌2. Zopinga za Kapangidwe ka Kapangidwe‌

• ‌Zolepheretsa za Mzere wa Microstrip‌:
• Zogawa mphamvu nthawi zambiri zimagwiritsidwa ntchito pogwiritsa ntchito mizere ya microstrip, yomwe ili ndi mphamvu zochepa zogwiritsira ntchito mphamvu komanso yosakwanira kusamalira kutentha (monga kukula kochepa, malo otsika kutentha).
• ResistorR‌sichipangidwira kutayikira kwamphamvu kwambiri, zomwe zimalepheretsa kudalirika kwa mapulogalamu ophatikiza.
• ‌Kuzindikira kwa Gawo/Mafupipafupi‌:
• Kusagwirizana kulikonse kwa gawo kapena mafupipafupi pakati pa zizindikiro ziwiri zolowera (zomwe zimapezeka nthawi zambiri m'zochitika zenizeni) kumawonjezera kutayika kwa mphamvu muR‌, kuonjezera kutentha kwa thupi.

‌3. Zolepheretsa pa Zochitika Zabwino Kwambiri Zokhudzana ndi Kusinthasintha/Kugwirizana kwa Gawo‌

• ‌Mlandu wa Chiphunzitso‌:
• Ngati zolowera ziwiri zili bwino kwambiri pa nthawi imodzi komanso pa nthawi imodzi (monga ma amplifiers ogwirizana omwe amayendetsedwa ndi chizindikiro chomwecho),Rsichichotsa mphamvu iliyonse, ndipo mphamvu yonse imaphatikizidwa paIN‌.
• Mwachitsanzo, ma input awiri a 50W akhoza kusakanikirana kukhala 100W paINngati mizere ya microstrip ingathe kuthana ndi mphamvu yonse.
• ‌Mavuto Ogwira Ntchito‌:
• Kulinganiza bwino magawo n'kosatheka kwambiri m'machitidwe enieni.
• Zogawa mphamvu sizili zolimba pakuphatikiza mphamvu zambiri, chifukwa ngakhale kusagwirizana pang'ono kungayambitseRkuyamwa mphamvu zosayembekezereka, zomwe zimapangitsa kuti zilephereke.

‌4. Kupambana kwa Mayankho Ena (monga, Ma Couplers Osakanikirana a 3dB)‌

• ‌Zolumikizira za 3dB Hybrid‌:
• Gwiritsani ntchito mapangidwe a m'mimba okhala ndi mphamvu zambiri zakunja, zomwe zimathandiza kuti kutentha kusamayende bwino komanso kuti mphamvu zambiri zigwiritsidwe ntchito (monga 100W+).
• Perekani padera pakati pa madoko ndipo lekererani kusalingana kwa magawo/mafupipafupi. Mphamvu yosafanana imayendetsedwa bwino kupita ku katundu wakunja m'malo mowononga zigawo zamkati.
• ‌Kusinthasintha kwa Kapangidwe‌:
• Mapangidwe ozikidwa pa m'khola amalola kuti kutentha kuyende bwino komanso kugwira ntchito bwino kwambiri pakugwiritsa ntchito mphamvu zambiri, mosiyana ndi zogawa mphamvu zochokera ku microstrip.

‌Mapeto‌

Zogawa mphamvu sizili zoyenera kugwiritsidwa ntchito pophatikiza mphamvu zambiri chifukwa cha mphamvu yochepa yogwiritsira ntchito mphamvu ya chotsukira chokha, kapangidwe kosakwanira ka kutentha, komanso kusamvana kwa magawo/mafupipafupi. Ngakhale m'magawo oyenera a co-phase, zoletsa za kapangidwe ndi kudalirika zimapangitsa kuti zikhale zosagwira ntchito. Pakuphatikiza ma siginolo amphamvu kwambiri, zida zapadera monga ‌Zolumikizira za 3dB zosakanizidwa‌amakonda kwambiri, amapereka kutentha kwabwino kwambiri, kupirira kusagwirizana, komanso kugwirizana ndi mapangidwe amphamvu kwambiri okhala ndi zibowo.

Concept imapereka mitundu yonse ya zida zogwiritsira ntchito ma microwave zomwe sizigwira ntchito zankhondo, zamlengalenga, zamagetsi, zakulankhulana ndi satelayiti, za kulumikizana ndi Trunking: chogawa mphamvu, cholumikizira cholunjika, fyuluta, duplexer, komanso zida zotsika mtengo za LOW PIM mpaka 50GHz, zokhala ndi mitengo yabwino komanso yopikisana.
