Beijing, August 21, 2025-Mu bintu ebikulaakulana amangu nga empuliziganya ya 5G, yintaneeti ya setilayiti, ne rada ya milimita-amayengo, ebiyungo bya RF coaxial bitundu bikulu mu kutambuza siginiini, era omulimu gwabyo gukosa butereevu obutebenkevu bw’enkola yonna. Olw’obwetaavu bw’ebintu ebikozesebwa mu kukola emirimu egy’amaanyi, bayinginiya boolekedde okusoomoozebwa okw’amaanyi ennyo. Gye buvuddeko, abakugu mu by’amakolero baafunza amagezi ttaano ag’omugaso okuyamba bayinginiya okulongoosa dizayini y’ebiyungo, okulongoosa obulungi bw’okugezesa, n’okwongera ku bulamu bw’ebyuma.
Amagezi 1: Londa okukwatagana kwa Impedance okutuufu
Impedance ya RF coaxial connectors (mu ngeri entuufu 50Ω oba 75Ω) erina okukwatagana obulungi n’enkola; bwe kitaba ekyo, okutunula kwa siginiini n’okufiirwa amaanyi bijja kuvaamu. "Mu milimita-wave frequency bands (okugeza, waggulu wa 28GHz), n'okukyama kw'ebipimo okwa mm 0.1 kuyinza okuleeta okuvunda okw'amaanyi mu SWR," bwatyo dayirekita w'ebyekikugu mu kkampuni ekola ebiyungo mu nsi yonna bwe yategeezezza. Bayinginiya balina okukulembeza nga bakozesa enkola ya standard impedance models eziweebwa omukozi n’okukakasa okukwatagana kwennyini nga bakozesa vector network analyzer (VNA).
Amagezi 2: Faayo ku kuyonja n’okulabirira enkola y’okukwatagana.
Ppini z’ebiyungo ne sockets zitera okufuuka oxidation n’ebisasiro by’ebyuma oluvannyuma lw’okuziyingiza n’okuziggyamu enfunda eziwera, ekivaako okweyongera okuziyiza okukwatagana. "Tukuwa amagezi okukozesa ppamba atalina mwenge-okuyonja ebifo ebikwatagana n'okuteeka ebikopo by'enfuufu mu mbeera enkambwe," yinginiya eyeenyigira mu kukola prototype ya 6G bwe yategeezezza. Ku mbeera ezeesigika ennyo- (nga okukozesa mu bwengula), obuwanvu bw’okusiiga zaabu bulina okusukka 1μm okutumbula okuziyiza okwambala.
Amagezi 3: Okulongoosa okufuga torque y’okussaako.
Okunyweza ennyo oba okunyweza ennyo kiyinza okukendeeza ku bulamu bw’ekiyungo. Ebiwandiiko by’amakolero biraga nti torque esengekeddwa ku biyungo bya SMA eri 0.7–1.0 N·m, ate ebiyungo ebituufu ebya mm 2.92 byetaaga obutuufu bwa 0.35 N·m. "Okukozesa ekisumuluzo ekitono ekya torque-limited kikendeeza ku nsobi z'abantu, ekikulu naddala mu kukola ebintu mu bungi," bwaggumiza maneja wa R&D ow'ekitongole ekikola ebyuma ebigezesebwa.
Amagezi 4: Okulongoosa obulungi bw’okuziyiza ku frequency enkulu.
Mu 5G millimeter wave frequency band, obutakola bulungi bwa connector shielding buyinza okuvaako ensonga z’okutaataaganyizibwa kw’amasannyalaze (EMI). Ebisembyeyo okugonjoola ebizibu mulimu okuziyiza emirundi esatu n’ebintu ebiziyiza amasannyalaze ebitono-dielectric-constant insulation materials. "Mu laabu yaffe, twakizudde nti okugattako PTFE (polytetrafluoroethylene) padding kiyinza okulongoosa shielding attenuation n'okusukka 10dB," omukulembeze wa ttiimu y'abanoonyereza mu yunivasite bwe yategeezezza.
Amagezi 5: Okugonjoola ebizibu mu bwangu
Enkola bw’efuna obutali bumativu bwa siginiini, bayinginiya basobola okukozesa enkola ey’emitendera esatu-okuzuula ensonga z’ekiyungo:
1. Okukebera n’amaaso: Weetegereze oba ppini ezifukamidde oba okusekula kwa plating;
2. Okugezesa time domain reflectometry (TDR): Funa obutakwatagana bwa impedance;
3. Enkola y’okukyusa: Kyuusa ekiyungo ekiteeberezebwa okukakasa ensonga.
"Ensobi za frequency enkulu-zitera okubaawo ku nsengekera z'ebiyungo essatu ezisooka. Okukulembeza ebifo bino kiyinza okukekkereza ebitundu ebisukka mu 50% eby'obudde bw'okugonjoola ebizibu," yinginiya omukulu owa RF bw'awa amagezi.
Industry Trend: Miniaturization ne high frequency bikwatagana mu ngeri ya parallel
Nga obunene bwa chip package bwe bukendeera, obwetaavu bw'ebiyungo ebitono ennyo (ultra-small connectors, ne 1.0mm ne 0.8mm, bweyongera mangu. Mu kiseera kye kimu, tekinologiya wa waveguide-to-coaxial conversion awagira frequency ezisukka 110 GHz afuuse ekifo eky’okunoonyereza n’okukulaakulanya. Abakugu balagula nti ebiyungo ebigezi ebirina okuliyirira ebbugumu okugatta bijja kufuuka bya bulijjo mpolampola mu myaka etaano egijja.
Mu bufunzi
Okulongoosa omulimu gw’ebiyungo bya RF coaxial kyetaagisa okugatta ennyo endowooza n’enkola. Okukuguka mu bukodyo obwo waggulu tekijja kukoma ku kulongoosa bulungibwansi bwa yinginiya wabula era kijja kuteekawo omusingi omunywevu ogw’omulembe oguddako-ebikozesebwa mu mpuliziganya. Nga omukugu omu mu by'amakolero bwe yagamba, "Ebikwata ku nsonga bye bisalawo obuwanguzi oba okulemererwa kwa siginiini za frequency enkulu-, era ebiyungo bye biri ku mutima gw'ebintu bino."
