Itekhnoloji yokucoca iMillimeter-wave (mmWave) licandelo elibalulekileyo ekwenzeni unxibelelwano olungenazingcingo lwe-5G oluqhelekileyo, ukanti lujongene nemiceli mngeni emininzi ngokwemilinganiselo yomzimba, ukunyamezelana kwemveliso, kunye nokuzinza kobushushu.
Kummandla wonxibelelwano olungenazingcingo oluqhelekileyo lwe-5G, ugxininiso lwexesha elizayo luya kutshintshela ekusebenziseni amaza angaphezulu kwe-20 GHz ngaphakathi kwe-mmWave spectrum ukunyusa umthamo we-bandwidth, ekugqibeleni ukonyusa amazinga othumelo.
Kuyaziwa ukuba ngenxa yokujikeleza okuphezulu kunye nokulahleka kwendlela ebalulekileyo, imiqondiso ye-mmWave ifuna ii-eriyali ezincinci. Ezi-eriyali zidityaniswe ndawonye ukuze zenze umqadi omxinwa, i-eriyali enenzuzo ephezulu.
Obunye ubunzima obuphambili kuyilo lokucoca kukuziqhelanisa nemilinganiselo ye-eriyali, ngakumbi kwizihluzi zefrikhwensi ephezulu. Ukongeza, ukunyamezela kwemveliso kunye nokuzinza kobushushu bezihluzi kuchaphazela kakhulu yonke inkalo yoyilo lwemveliso kunye nemveliso.
Izithintelo zobungakanani kwi-mmWave Technology
Kwiinkqubo zoluhlu lwe-eriyali yesiqhelo, isithuba phakathi kwezinto kufuneka sibe ngaphantsi kwesiqingatha sobude bobude ( λ/2 ) ukunqanda uphazamiseko. Lo mgaqo usebenza ngokulinganayo kwii-eriyali ezikhanyayo ze-5G. Umzekelo, i-eriyali esebenza kwibhendi ye-28 GHz ine-elementi yokubeka isithuba esimalunga ne-5 mm.
Uluhlu lwezigaba eziqeshwe kwizicelo ze-mmWave zihlala zithatha uyilo lwesakhiwo esicwangcisiweyo, njengoko kubonisiwe ngezantsi, apho ii-eriyali (iindawo ezityheli) zixhonywe kwiibhodi zesekethe eziprintiweyo (PCBs) (iindawo eziluhlaza), kunye neebhodi zesekethe (iindawo eziluhlaza) zinokudityaniswa ngokuthe ngqo kwi ibhodi ye-eriyali.
Isithuba kwezi bhodi zesekethe sele sincinci, kodwa itekhnoloji ekhulayo iphonononga ngakumbi izakhiwo ezixineneyo, okuthetha ukuba izihluzi kunye nezinye iibhloko zesekethe kufuneka zibe zincinci kakhulu ukuze zifakwe ngqo ngasemva kwe-eriyali PCB.
Impembelelo yokuVeliswa koNyamezelo kwizihluzi
Ngenxa yokubaluleka kwezihluzo ze-mmWave, ukunyamezelana kwemveliso kudlala indima ebalulekileyo, kuphembelela ukusebenza kohluzo kunye neendleko.
Ukuphinda siphande ezi zinto, sithelekise iindlela ezintathu ezahlukeneyo zokwenziwa kohluzo lwe-26 GHz:
Le theyibhile ilandelayo ichaza unyamezelo olugqithisileyo olufunyanwa kwimveliso:
Ukunyamezelwa kweMpembelelo kwi-PCB Microstrip Filters
Njengoko kubonisiwe ngezantsi, uyilo lokucoca imicrostrip luyaboniswa.
Uyilo lwegophe lokulinganisa luhamba ngolu hlobo lulandelayo:
Ukuphonononga isiphumo sonyamezelo kule PCB microstrip filter, ezisibhozo ukunyamezelana okugqithisileyo kwakhethwa, ebonisa umahluko ophawulekayo.
Ukunyamezelwa kweMpembelelo kwi-PCB Stripline Filters
Uyilo lokucoca umgca we-stripline, oluboniswe ngezantsi, luyisakhiwo esinamanqanaba asixhenxe kunye neebhodi ze-dielectric ze-30 mil RO3003 phezulu nasezantsi.
I-roll-off ingaphantsi komnqantsa, kwaye i-coefficient yoxande ingaphantsi kuneyo ye-microstrip ngenxa yokungabikho kwe-zero kufuphi ne-passband, okukhokelela ekusebenzeni okusemgangathweni kwe-harmonic kwi-frequencies ezikude.
Ngokufanayo, uhlalutyo lokunyamezela lubonisa uvakalelo olungcono xa kuthelekiswa nemigca ye-microstrip.
Ukuqukumbela
Kunxibelelwano olungenazingcingo lwe-5G ukufikelela kwizantya ezikhawulezayo, itekhnoloji yokucoca i-mmWave esebenza kwi-20 GHz okanye i-frequencies ephezulu iyimfuneko. Nangona kunjalo, imiceli mngeni iyaqhubeka ngokwemilinganiselo yomzimba, uzinzo lokunyamezelana, kunye nobunzima bokuvelisa.
Ngoko ke, impembelelo yokunyamezelana kuyilo kufuneka iqwalaselwe ngononophelo. Kuyabonakala ukuba izihlungi ze-SMT zibonakalisa ukuzinza okukhulu kune-microstrip kunye nezihluzo ze-stripline, ezibonisa ukuba izihlungi ze-SMT ze-surface-mounting zingavela njengeyona nto ikhethiweyo yonxibelelwano lwe-mmWave yexesha elizayo.
