Project Overview
YDRGDW20Q is a digital band-selective repeater with a medium-low RF output power of 20dBm. It support three bands(B1/B3/B8) with adjustable bandwidth available on each of the three supported bands. There are 4 sub-bands(20MHz ) in total supported by this model, 1 sub-band for B1 and B8, two for B3.
Key Features
• Digital bandwidth-adjustable features allow for seamless adaptability to different frequency bands.
• LCD display the input/output signal strength.
• Auto isolation detection.
• Improve any three mobile networks at the same time.
• Support 3 bands(B1/B3/B8,adjustable bandwidth from 0.2 to 20MHz for each band).
• Built-in Auto Gain Control (AGC)& Auto Level Control (ALC).
• Center frequency movable.
• OMS Lite for remote/local control and monitoring(Optional)
