Coaxial RF connectors ni gaw Microwave ginra hta ahkyak ai RF shapoi ai arung arai ni rai nna, Microwave jak/hpaji amyu myu, Microwave matut mahkai arung arai ni, jak rung ni hte radar system ni hta grai law hkra jai lang nga ai.
RF coaxial connector amyu myu: Kade nna ai aten hta wireless matut mahkai lam hte radar hpaji masa ni lawan ladan rawt jat wa ai majaw, system htawn shabra ai shara hpe jat wa na matu system htawn shabra ai atsam hpe jat wa hkra galaw ra ai. Microwave system ting a daw langai hku nna, RF coaxial connector ni gaw, n-gun kaba -shapoi ya ra ai lam ni hpe hkam sharang lu ra ai. RF engineer ni mung -n-gun kaba ai chyam dinglik ai lam hte shadawn shadang ni hpe ayan galaw ma ai, chyam dinglik na matu lang ai Microwave jak amyu myu hte arung arai ni mung n-gun kaba ai -arung arai ni ra nga ai. Ndai lam gaw RF coaxial matut mahkai ai atsam hpe madung madun ai RF coaxial matut mahkai ai atsam hpe grau grau nna ra sharawng ai lam hpe shabyin ya nga ai. Dai majaw, RF coaxial connector ni a power atsam hpe kade daram chye ai kun? RF coaxial connector ni a power capacity gaw grai sawng ai lam langai rai nna, lam law law a majaw byin pru wa ai, nkau mi gaw langai hte langai matut mahkai nga ai. Ndai lam ni hta madung hku nna, connector kaba ai (pinhole kaba ai lawm ai), bungli galaw ai aten, hkum hkrang arung arai, n-gun n rawng ai arung arai, matut mahkai ai lam hpe kam mai ai lam, matut mahkai ai lam hpe ninghkap lu ai atsam, voltage standing wave ratio (VSWR), grup yin nbung katsi ai lam, tsaw ai shara ni lawm ai. Lawu na sumla hta Megaphase kaw nna n bung ai frequency ni hta RF connector amyu myu a matu hpaji jaw da ai power capacity manu ni hpe madun da ai. RF product ni hpe design galaw ai shaloi, dai product a bungli galaw ai frequency hte power hpe hkam la lu ai atsam hpe madung tawn nna, gingdan ai connector hpe lata la mai ai.
Hpang e, RF coaxial connector ni a power atsam hpe hkra machyi shangun ai lam ni hpe hkrak tup sang lang dan na re. Frequency langai sha re ai RF signal ni a matu, kaba ai connector ni gaw power hpe grau hkam sharang lu ai atsam nga ai. Ga shadawn, connector pinhole size gaw connector a ya na n-gun hte matut mahkai nga ai, dai gaw power hte hkrak matut mahkai nga ai. Masha law malawng lang ai RF coaxial matut mahkai ai lam ni hta, 7/16 (DIN), 4.3-10, hte N-hpan matut mahkai ai lam ni gaw grai kaba ai, grau kaba ai pinhole size ni hte bung ai.

Ndai N-hpan n-gun jat wa ai lam gaw, gat lawk hta dut shabra ai passive component law malawng, attenuator hte 200W jan n-gun rating nga ai load ni hta, N-hpan n-gun jat wa ai lam hpe sang lang dan nga ai. RFbuy (www.rfbuy.com) gaw n-gun kaba ai-n-gun shayawm ai jak ni, kaga n-gun shayawm ai jak ni hpe loi loi hte lu la mai ai. RF coaxial connector ni a power hpe hparan lu ai atsam gaw signal frequency law wa ai hte maren yawm mat wa ai. Hkrang shala ai signal frequency galai shai ai lam gaw, shapoi ai sum ai lam hte voltage standing wave ratio (VSWR) hpe hkrak hkra machyi shangun nna, dai gaw shapoi ai n-gun atsam hpe mung hkra machyi shangun ai. Dai hta n-ga, hkum hkrang hta byin ai hkra machyi lam ni mung byin chye ai. Ga shadawn, SMA connector langai mi gaw 2GHz hta 500W daram n-gun hkam la lu ai atsam nga ai, raitim 18GHz hta gaw 100W daram n-gun hkam la lu ai atsam nga ai. RFbuy RF Mall (www.rfbuy.com) hku nna, 18 GHz jan ai frequency hta bungli galaw ai attenuator hte load zawn re ai passive component law malawng gaw, 100 W hta n-pu na n-gun atsam hpe hkam la lu ai.
