Beijing, August 21, 2025-Lawan ai hku rawt jat wa nga ai 5G matut mahkai lam, satellite internet, millimeter{5}}wave radar zawn re ai ginra ni hta, RF coaxial matut mahkai lam ni gaw signal shapoi na matu ahkyak ai arung arai ni rai nna, shanhte a bungli galaw ai lam gaw, system ting a ngang grin ai lam hpe hkrak hkrak hkra machyi shangun nga ai. High-frequency application ni hpe ra sharawng ai lam law wa ai majaw, engineer ni gaw grau sawng ai mayak mahkak ni hpe hkrum sha nga ai. Kade nna ai aten hta, hpaga lam hpaji ninghkring ni gaw, engineer ni hpe connector design hpe grau kaja hkra galaw na matu, chyam dinglik ai lam hpe grau kaja hkra galaw na matu, jak rung ni a prat hpe galu kaba hkra galaw na matu karum ya lu ai tatut galaw mai ai hpaji jaw ga 5 hpe kadun dawk tsun dan ma ai.
Hpaji jaw ga 1: Teng man ai Impedance hpe lata la u
RF coaxial connector ni a impedance (ga shadawn 50Ω (sh) 75Ω) gaw system hte hkrak hkrak rai ra ai; n rai yang, signal n-gun yawm mat nna, power sum mat na re. "Millimeter-wave frequency bands ni hta (ga shadawn, 28GHz jan) 0.1mm daram n-gun n bung ai sha pyi SWR hta grai hkra machyi shangun chye ai," nga nna mungkan ting na connector galaw ai company langai a hpaji hparat hpa-awn langai tsun ai. Engineer ni gaw, galaw shapraw ai wa jaw ai madang masat da ai n-gun atsam hpe jai lang nna, vector network analyzer (VNA) hpe jai lang nna, tengman ai htuk manu ai lam hpe jep joi ra na re.
Tip 2: Contact interface hpe san seng hkra galaw na matu hte gram lajang na matu sadi u.
Connector pin hte socket ni hpe lang hte lang bang nna shaw kau ai hpang oxidation hte metal debris ni byin chye ai majaw, matut mahkai ai lam hpe ninghkap lu ai atsam grau law wa ai. "Anhte gaw, alcohol-n lawm ai cotton swab hpe lang nna, matut mahkai ai lam ni hpe jasan jaseng na matu hte, n hkru n kaja ai shara ni hta, nhprang wan shingnip ni hpe bang na matu hpaji jaw ga ai," nga nna 6G prototype galaw ai hta shang lawm ai engineer langai tsun ai. Hpa majaw nga yang, n-gun ja ai-kam hpa mai ai lam ni a matu (aerospace application zawn re ai ni) ja n-gun hpe 1μm hta jan nna, n-gun n-gun jat wa hkra galaw ra ai.
Tip 3: Install galaw ai torque hpe grau kaja hkra galaw u.
Grai n-gun ja ai (sh) n-gun n-ja ai gaw connector a prat hpe kadun shangun chye ai. Industry data hku yu yang, SMA matut mahkai lam a matu hpaji jaw da ai torque gaw 0.7–1.0 N·m rai nna, 2.92mm hkrak ai matut mahkai lam a matu gaw 0.35 N·m hkrak ai lam ra ai. "Torque-limited wrench hpe lang ai gaw shinggyim masha ni a shut ai lam hpe shayawm ya lu ai, dai gaw grau nna law law galaw shapraw ai hta ahkyak ai," nga nna chyam dinglik arung arai galaw ai company langai a R&D manager wa ahkyak shatai tsun ai.
Tip 4: Frequency kaba ni hta shielding galaw ai lam hpe grau kaja hkra galaw u.
5G millimeter wave frequency band hta, n-gun n-htuk ai connector hpe makawp maga ai atsam n nga ai majaw, wan n-gun n-gun n-gun (EMI) manghkang ni byin chye ai. Hpang jahtum na hparan ladat ni hta, masum lang makawp maga ai hte n-gun n law ai-dielectric-n-gun n rawng ai arung arai ni lawm ai. "Anhte a Lab hta, PTFE (polytetrafluoroethylene) padding hpe jat bang ai gaw, shingnip shingna hpe 10dB jan shayawm ya lu ai hpe mu lu ai," nga nna dakkasu sawk sagawn hpung ningbaw langai tsun ai.
Tip 5: Manghkang hpe lawan ai hku hparan na
System langai mi hta signal n kaja ai lam ni byin wa ai shaloi, engineer ni gaw connector manghkang ni hpe tam na matu, lahkam masum- ladat hpe lang mai ai:
1. Myi man hte yu ai: Bent pins (sh) plating peeling nga ai hpe yu u;
2. Aten domain reflectometry (TDR) chyam dinglik ai lam: Impedance n matut manoi ai lam ni hpe tam sawk sagawn ai;
3. Galai shai ai ladat: Manghkang hpe jep yu na matu, myit tsang ai connector hpe galai kau ra ai.
"High-frequency n kaja ai lam ni gaw shawng na connector interface masum hta law law lang byin chye ai. Ndai shara ni hpe ahkyak shatai nna galaw ai gaw manghkang hparan ai aten hpe 50% jan hkye la lu ai," nga nna RF engineer kaba langai hpaji jaw ai.
Hpaga lam masa: Kaji kajaw galaw ai lam hte nsen kaba ai lam gaw maren sha hpawng de wa ai
Chip package size ni yawm wa ai hte maren, 1.0mm hte 0.8mm pyi ultra-kaji ai matut mahkai lam ni hpe ra sharawng ai lam gaw lawan ladan rawt jat wa nga ai. Dai aten hta sha, 110 GHz jan na frequency ni hpe madi shadaw ya ai waveguide-to-coaxial galai shai ai hpaji masa gaw sawk sagawn ai lam hte rawt jat galu kaba wa ai lam hta grai ahkyak ai shara langai byin wa sai. Hpaji ninghkring ni tsun ai hta, du na 5 ning laman hta, nbung katsi ai hpe gram lajang ya lu ai hpaji rawng ai connector ni gaw, loi loi hte n-gun rawng wa na re.
Daw dan lam
RF coaxial connector ni a bungli hpe grau kaja hkra galaw na matu, theory hte practice hpe sung sung hpawng de ra ai. Lahta na ladat ni hpe atsawm chye na ai gaw, engineering hpaji hpe grau kaja hkra galaw ya lu ai sha n-ga, hpang na-prat na matut mahkai lam a matu ngang kang ai npawt nhpang hpe mung gawgap ya lu na re. Industry hpaji ninghkring langai tsun ai hte maren, "Details gaw high-frequency signal ni a awng dang ai lam (sh) hkrat sum ai lam hpe dawdan ya ai, connectors ni gaw ndai details ni a madung rai nga ai."
