Millimeter-wave (mmWave) filter technology is a crucial component in enabling mainstream 5G wireless communication, yet it faces numerous challenges in terms of physical dimensions, manufacturing tolerances, and temperature stability.
Mu nkuru yimbere 5G itumanaho ridafite umugozi, Ibyibatsikiriho bizahinduranya kugirango dukoreshe inshuro ziri hejuru ya 20 GHZ muri SHZRUM yo kuzamura ubushobozi bwa bande, amaherezo yongera ibiciro byoherejwe.
Birazwi neza ko bitewe numubare wabo mwinshi ninzira ikomeye yo gutakaza, ibimenyetso bya MMwave bisaba antene nto. Izi ntenna zishyizwe hamwe kugirango zishyireho urumuri-rutam, inyungu-ndende Antenna.
Kimwe mu bibazo by'ibanze mu gushushanya ibishushanyo mbonera mu kumenyera ibipimo bya Antenna, cyane cyane kuyungurura. Byongeye kandi, kwihanganira ubushyuhe nubushyuhe bugabanya ingaruka kuburyo buri kintu cyibicuruzwa no gutanga umusaruro.
Ingano yubunini muri tekinoroji ya MMwave
Muri sisitemu gakondo ya antenna barray, intera iri hagati yibintu igomba kuba munsi ya kimwe cya kabiri cyuburebure (λ / 2) kugirango wirinde kwivanga. Iri hame rikoreshwa kimwe kuri 5G mbi. Kurugero, antenne ikorera muri 28 GHZ itsinda ryabapima hafi 5 mm.
IHURIRO RY'IGIHUGU BAKORESHEJWE MU BIKORWA MMWAVE AGACIRO BY'UBUYOBOZI BW'UBUYOBOZI, nkuko bigaragara hano hepfo, aho antennas (PCB) yashyizwe ku bibaho byacapwe (PCB), hamwe n'ibibaho by'umuzunguruko) bishobora guhuzwa mu kibaho cya Anteni.
Umwanya uri kuri iyi mbaho zumuzunguruko zisanzwe, ariko ikoranabuhanga rigaragara ni ugushakisha ndetse no muyungurura hamwe nibindi bikoresho bigize umuzunguruko bigomba kuba bito cyane bigomba kuzenguruka inyuma ya antenne PCB.
Ingaruka zo Gukora Inganda Kuyungurura
Urebye akamaro ka mmave muyunguruzi, gukora kwihanganira bigira uruhare runini, bigira ingaruka kubijyanye no kuyungurura ibikorwa nibiciro.
Kugirango ukomeze gukora iperereza kuri izi ngingo, twagereranije ibintu bitatu bitandukanye 26 GHZ yo kuyungurura uburyo:
Imbonerahamwe ikurikira iragaragaza kwihanganira ibintu bikabije byahuye nibikorwa:
Ingaruka zo kwihanganira kuri PCB Microstrip Kuyunguruzi
Nkuko bigaragara hano hepfo, imiterere ya microstrip iyungurura iragaragaza.
Igishushanyo cyo kwigana ni ibi bikurikira:
Kugira ngo wige ingaruka zo kwihanganira kuri iyi pcb filter, kurwara umunani bishobora kwihanganira byatoranijwe, byerekana itandukaniro rigaragara.
Ingaruka zo kwihanganira kuri PCB Stripline
Igishushanyo cya Stripline, cyerekanwe hepfo, nimiterere irindwi-stage hamwe na mil ro3003 kurira kuri hejuru no hepfo.
Kuzunguruka ntibihagije, kandi urukiramende ruruta ruri munsi ya microstrige kubera kubura Zeros hafi ya Passesh, bikaviramo imikorere ya Suboptal hafi ya kure.
Mu buryo nk'ubwo, isesengura ryitonda ryerekana sentitivitivitivitivitivitivitivitivitivitivitivitivitivitivitivitic hamwe n'imirongo iciriritse.
Umwanzuro
Kuri 5g itumanaho rya 5G kugirango ugere ku muvuduko wihuse, MMwave Akayunguruzo Ikoranabuhanga rikorera kuri 20 GHZ cyangwa inshuro ziri hejuru ni ngombwa. Ariko, ibibazo bikomeza ibipimo byumubiri, gutura neza, no gukora ibintu.
Rero, ingaruka zo kwihanganira ibishushanyo zigomba gusuzumwa neza. Biragaragara ko smt muyungurura neza kurenza microstrikingi na stripline muyunguruzi, byerekana ko umusozi wa SMT-umusozi ushobora guhita kugaragara nkitumanaho rya MMwave ejo hazaza.
