Chifukwa Chake Ogawa Mphamvu Sangagwiritsidwe Ntchito Monga Ophatikiza Mphamvu Zapamwamba

Kulephera kwa magawo ogawa mphamvu pakuphatikiza mphamvu zambiri kumatheka chifukwa cha izi:

pa1. Zochepa Zogwirira Ntchito Zamphamvu za Isolation Resistor (R)pa

• paPower Divider Mode:
• Mukagwiritsidwa ntchito ngati chogawa mphamvu, chizindikiro cholowera paINAmagawidwa m'magulu awiri, ma co-phase sign pa mfundoAndiB.
• The isolation resistorRSimakumana ndi kusiyanasiyana kwamagetsi, zomwe zimapangitsa kuti ziro ziziyenda komanso sizitha mphamvu. Mphamvu yamagetsi imatsimikiziridwa kokha ndi mphamvu ya chingwe cha microstrip.
• paCombiner Mode:
• Akagwiritsidwa ntchito ngati chophatikiza, zizindikiro ziwiri zodziyimira pawokha (kuchokeraOUT1ndiOUT2() ndi ma frequency kapena magawo osiyanasiyana amayikidwa.
• Kusiyana kwamagetsi kumachitika pakati pawoAndiB, kuchititsa kuyenda kwamakonoR. Mphamvu zidathaRzofanana½(OUT1 + OUT2). Mwachitsanzo, ngati cholowetsa chilichonse ndi 10W,RIyenera kupirira ≥10W.
• Komabe, chodziletsa chodzipatula pazigawo zogawira magetsi nthawi zambiri chimakhala champhamvu chochepa chokhala ndi kutentha kosakwanira, zomwe zimapangitsa kuti pakhale kulephera kwamphamvu kwambiri.

pa2. Zolepheretsa Zomangamangapa

• paMiyeso ya Microstrip Line:
• Zogawa zamagetsi nthawi zambiri zimagwiritsidwa ntchito pogwiritsa ntchito mizere ya microstrip, yomwe ili ndi mphamvu zochepa zogwiritsira ntchito mphamvu komanso kusamalidwa kokwanira kwa kutentha (mwachitsanzo, kukula kochepa kwa thupi, malo ochepetsera kutentha).
• The resistorRSizinapangidwe kuti ziwonongeke zamphamvu kwambiri, zomwe zimalepheretsanso kudalirika pamapulogalamu ophatikiza.
• paPhase/Frequency Sensitivity:
• Gawo lililonse kapena kusagwirizana pafupipafupi pakati pa ma siginecha awiriwa (odziwika muzochitika zenizeni) kumawonjezera kutha kwa mphamvu muR, kukulitsa kupsinjika kwa kutentha.

pa3. Zochepa muzochitika zabwino za Co-Frequency / Co-Phasepa

• paTheoretical Mlandu:
• Ngati zolowetsa ziwiri ndizofanana bwino komanso gawo limodzi (mwachitsanzo, zokulitsa zolumikizira zomwe zimayendetsedwa ndi chizindikiro chomwecho), ‌RSimawononga mphamvu, ndipo mphamvu yonse imaphatikizidwa paIN.
• Mwachitsanzo, zolowetsa ziwiri za 50W zitha kuphatikizana kukhala 100W pa ‌INNgati mizere ya microstrip imatha kuthana ndi mphamvu zonse.
• paMavuto Othandiza:
• Kuyanjanitsa koyenera kwa gawo kuli pafupifupi kosatheka kukhalabe mu machitidwe enieni.
• Ogawa mphamvu alibe mphamvu zophatikizira mphamvu zambiri, chifukwa ngakhale kusagwirizana pang'ono kungayambitseRkuyamwa mafunde amphamvu mosayembekezereka, zomwe zimapangitsa kulephera.

pa4. Kupambana kwa Njira Zina (mwachitsanzo, 3dB Hybrid Couplers)pa

• pa3dB Zophatikiza Zophatikiza:
• Gwiritsani ntchito zida zapabowo zokhala ndi zoletsa zamphamvu zakunja, zomwe zimapangitsa kuti pakhale kutentha koyenera komanso mphamvu yayikulu yogwiritsira ntchito mphamvu (mwachitsanzo, 100W+).
• Perekani kudzipatula pakati pa madoko ndi kulolera kusagwirizana kwa gawo/mafuwidwe. Mphamvu zosagwirizana zimapatutsidwa motetezeka ku katundu wakunja m'malo mowononga zida zamkati.
• paKusinthasintha kwapangidwe:
• Mapangidwe opangidwa ndi ma cavity amalola kuwongolera kwamphamvu kwamafuta ndi magwiridwe antchito amphamvu pamapulogalamu apamwamba kwambiri, mosiyana ndi ogawa magetsi opangidwa ndi microstrip.

paMapetopa

Zogawa zamagetsi ndizosayenera kuphatikiza mphamvu zambiri chifukwa cha mphamvu yodzipatula yokhayokha, kusakwanira kwa matenthedwe, komanso kusamvana kwa magawo / pafupipafupi. Ngakhale muzochitika zabwino zamagulu, zovuta zamapangidwe ndi zodalirika zimapangitsa kuti zikhale zosatheka. Pophatikiza ma siginecha amphamvu kwambiri, zida zodzipatulira monga3dB hybrid couplersZokondedwa, zopatsa mphamvu zotentha kwambiri, kulolerana ndi zolakwika, komanso zogwirizana ndi mapangidwe apamwamba amphamvu kwambiri.

Lingaliro limapereka zida zonse za ma microwave ankhondo, Azamlengalenga, Electronic Countermeasures, Satellite Communication, Trunking Communication application: Power divider, directional coupler, fyuluta, duplexer, komanso LOW PIM zigawo mpaka 50GHz, zokhala ndi zabwino komanso zopikisana.
