RF Duplexer
Cholumikizira cha cavity duplexer ndi mtundu wapadera wa cholumikizira cha duplexer chomwe chimagwiritsidwa ntchito mumakina olumikizirana opanda zingwe kuti chilekanitse zizindikiro zotumizidwa ndi zolandiridwa mu gawo la ma frequency. Cholumikizira cha cavity duplexer chimakhala ndi ma resonant cavities awiri, omwe ali ndi udindo wolumikizana mbali imodzi.
Mfundo yogwirira ntchito ya cavity duplexer imachokera pa kusankha ma frequency, komwe kumagwiritsa ntchito cavity yeniyeni ya resonant kuti itumize ma signal mosankha mkati mwa ma frequency range. Makamaka, chizindikiro chikatumizidwa mu cavity duplexer, chimatumizidwa ku cavity inayake ya resonant ndipo chimakulitsidwa ndikutumizidwa pa resonant frequency ya cavity imeneyo. Nthawi yomweyo, chizindikiro cholandiridwacho chimakhalabe mu cavity ina ya resonant ndipo sichidzatumizidwa kapena kusokonezedwa nacho.

Kuphatikiza kwa RFTYT RF Hybrid Combiner Signal ndi Amplification
Chosakaniza cha RF hybrid, chomwe ndi gawo lofunika kwambiri pa njira zolumikizirana opanda zingwe ndi radar ndi zida zina zamagetsi za RF, chagwiritsidwa ntchito kwambiri. Ntchito yake yayikulu ndikusakaniza ma signal a RF olowera ndi kutulutsa ma signal atsopano osakanikirana. Chosakaniza cha RF Hybrid chili ndi mawonekedwe a kutayika kochepa, mafunde ang'onoang'ono oyima, kudzipatula kwakukulu, kukula kwabwino kwa amplitude ndi phase balance, komanso ma inputs ndi outputs angapo.
RF Hybrid Combiner ndi kuthekera kwake kopeza kulekanitsa pakati pa zizindikiro zolowera. Izi zikutanthauza kuti zizindikiro ziwiri zolowera sizidzasokonezana. Kulekanitsa kumeneku ndikofunikira kwambiri pamakina olumikizirana opanda zingwe ndi ma amplifier amphamvu a RF, chifukwa kumatha kuletsa kusokonezeka kwa chizindikiro ndi kutayika kwa mphamvu.

Zolumikizira za RFTYT Low PIM Zophatikizidwa kapena Zotseguka
Cholumikizira chapakati pa ma modulation otsika ndi chipangizo chomwe chimagwiritsidwa ntchito kwambiri m'makina olumikizirana opanda zingwe kuti achepetse kusokonekera kwa ma intermodulation m'zida zopanda zingwe. Kusokonekera kwa ma intermodulation kumatanthauza chochitika chomwe zizindikiro zingapo zimadutsa mu dongosolo losakhala la mzere nthawi imodzi, zomwe zimapangitsa kuti pakhale mawonekedwe a zigawo za pafupipafupi zomwe sizilipo zomwe zimasokoneza zigawo zina za pafupipafupi, zomwe zimapangitsa kuti magwiridwe antchito a dongosolo la opanda zingwe achepe.
Mu machitidwe olumikizirana opanda zingwe, ma coupler otsika pakati pa ma modulation nthawi zambiri amagwiritsidwa ntchito kulekanitsa chizindikiro champhamvu kwambiri cholowera ndi chizindikiro chotulutsa kuti achepetse kusokonekera kwa ma intermodulation.

Cholumikizira cha RF (3dB, 10dB, 20dB, 30dB)
Cholumikizira ndi chipangizo cha microwave chomwe chimagwiritsidwa ntchito kwambiri pogawa zizindikiro zolowera ku ma doko angapo otulutsa, ndipo zizindikiro zotuluka kuchokera ku doko lililonse zimakhala ndi ma amplitude ndi magawo osiyanasiyana. Chimagwiritsidwa ntchito kwambiri mu makina olumikizirana opanda zingwe, makina a radar, zida zoyezera ma microwave, ndi zina.
Zolumikizira zitha kugawidwa m'mitundu iwiri malinga ndi kapangidwe kake: microstrip ndi cavity. Mkati mwa cholumikizira cha microstrip mumapangidwa makamaka ndi netiweki yolumikizira yokhala ndi mizere iwiri ya microstrip, pomwe mkati mwa cholumikizira cha cavity mumapangidwa ndi mizere iwiri yachitsulo.
