27dBm Lte & Wcdma 18002100MHz 2G 3G 4G ALC Dual-Band Signal Extender Amplifier Lte Mobile Network Repeater Cell Phone Signal Booster yog tsuas yog siv los pab cellular Base Station (BTS) lossis Repeaters los daws teeb meem sab hauv tsev qhov muag tsis pom qhov chaw, nws txoj haujlwm feem ntau yog them nyiaj poob haujlwm hauv- lub tsev faib cable, fais fab splitter thiab directional coupler, thiab txuas ntxiv nyob rau hauv lub tsev teeb liab kev pab them nqi, thiab txhim kho saj zawg zog ntawm nyob rau hauv lub tsev teeb liab kev pab them nqi system tsim kom tau raws li qhov yuav tsum tau ntawm lub zog ntawm lub tsev teeb liab kev pab them nqi system.
Dual band repeater nta:
1.Customized 2-bands zaus, xws li 900/1800MHz, 900/2100MHz, 900/2600MHz, 1800/2100MHz, 1800/2600MHz, 2100/2600MHz, 850/1900MHz thiab lwm yam kom tau raws li qhov sib txawv network signals thov;
2.Nrog MGC muaj nuj nqi, (Manual Gain Control), Cov neeg tuaj yeem kho qhov nce raws li xav tau;
3.Nrog DL teeb liab LED zaub, pab txhim kho lub kav hlau txais xov sab nraum zoov ntawm lub xeev zoo tshaj plaws;
4. Nrog AGC thiab ALC, ua kom rov ua haujlwm ruaj khov.
5.PCB nrog kev ua haujlwm cais, ua rau UL thiab DL teeb liab tsis cuam tshuam ib leeg,
6.Low intermodulation, siab nce, ruaj khov tso zis zog
