Wide-Band Directional Coupler 698-2700MHz N
Telsto Wide band Directional couplers muab kev sib txuas ncaj nraim ntawm ib txoj kev teeb liab mus rau lwm qhov hauv ib qho kev taw qhia nkaus xwb (lub npe hu ua cov lus qhia).Lawv feem ntau muaj cov kab txuas txuas txuas hluav taws xob mus rau ib txoj kab tseem ceeb.Ib qho kawg ntawm txoj kab pabcuam txuas mus tas li nrog kev sib tw ua tiav.Cov lus qhia (qhov sib txawv ntawm kev sib txuas hauv ib qho kev taw qhia piv rau lwm qhov) yog kwv yees li 20 dB rau cov khoom sib txuas, Cov kev taw qhia txuas tau siv thaum twg ib feem ntawm lub teeb liab yuav tsum tau muab cais tawm lossis ob lub cim yuav tsum tau ua ke.Telsto muaj qhov nqaim band thiab wireless band directional couplers nrog kev sib txuas ntawm 3 dB txog 50 dB lossis ntau dua.

stripping qhov ntev yog raws li qhia los ntawm daim duab (Fig2), yuav tsum tau them nyiaj mloog thaum stripping:
1. Qhov kawg nto ntawm tus neeg xyuas pib sab hauv yuav tsum tau chamfered.
2. Tshem tawm cov impurities xws li tooj liab nplai thiab burr ntawm qhov kawg ntawm lub cable.
Sib dhos qhov sib khi: Screw lub sealing ib feem nyob rau hauv raws li tus neeg xyuas pib ntawm lub cable raws li qhia los ntawm daim duab (Fig3).
Sib sau cov txiv ntoo qab (Fig 3).
Muab cov txiv ntseej rau pem hauv ntej thiab nraub qaum los ntawm screwing raws li qhia hauv daim duab (Figs(5)
1. Ua ntej screwing, smear ib txheej ntawm lubricating roj ntawm lub o-ring.
2. Khaws lub nraub qaum thiab lub cable tsis txav, ntsia hlau rau ntawm lub plhaub tseem ceeb ntawm lub plhaub sab nraub qaum.Screw lub plhaub tseem ceeb ntawm lub plhaub rov qab lub cev siv lub dab teg liab.Kev sib dhos tiav lawm.
