Tetra 380MHz Band Selective 380-385 MHZ 390-395 MHZ Ob Txoj Kev Xov Tooj Cua UHF Sab Nraud Sab Nraud Repeater Amplifier nrog RJ45
Cov zaus band 380-385 MHz (uplink) / 390-395 MHz (downlink) yog tsim los daws cov teeb meem ntawm cov teeb liab tsis muaj zog, uas yog pheej yig dua li ntxiv qhov chaw nres tsheb tshiab (BTS).Lub luag haujlwm tseem ceeb ntawm RF Bi-Directional Amplifiers system yog kom tau txais cov teeb liab hluav taws xob tsawg los ntawm BTS los ntawm kev xa xov tooj cua zaus thiab tom qab ntawd xa cov teeb liab amplified mus rau thaj chaw uas cov kev pab them nqi network tsis txaus.Thiab lub teeb liab ntawm lub xov tooj ntawm tes kuj tau nthuav dav thiab xa mus rau BTS ntawm qhov kev coj ua.
Cov khoom tseem ceeb:
● Nrog modularized tsim, yooj yim rau tu
● Software chaw taws teeb saib xyuas (serial chaw nres nkoj), yooj yim rautu thiab tswj.
● IP55 plua plav pov thawj & tsis muaj dej, nrog rau qhov yuav tsum tau muaj tsawg ntawm kev teeb tsa ib puag ncig;
● Nrog high-linearity fais fab amplifier thiab high-rejection duplexer, muaj peev xwm ntawm tsis kam intermodulation thiab spurious signals
