JDCR-DB Series (+17dBm)

Dual Band Consumer Repeater

Product Overview

The JDCR-DB Series Cellular Repeater is a medium-powered, gain adjustable dual band repeater that is perfect for use in a DAS application needing to provide enhanced coverage for Voice + 3G or 4G high speed data to an office building, department store, warehouse, underground parking lot, or small multi-story hotel. Our repeaters are built with carrier level optimization in mind and thus use very high quality internal components to achieve this. These include low noise amplifiers with high linearity, properly specified  and set output power limits and well designed alarm/protection circuitry.

A main feature standard on all our repeaters are individually assigned Uplink and Downlink attenuation adjustment DIP switches. This is particularly advantageous when optimizing your repeater for LTE to ensure you get the best throughput speeds.  

A certified test report is included with each repeater that leaves our factory, so you are assured of strict quality controls.

To maintain safe and specific output signal levels, this advanced repeater has built-in AGC (Automatic Gain Control) and ALC (Automatic Limit Control) circuits which can automatically control the gain of the repeater within a 15dB range depending on the RF environmental conditions. In addition, it also has built-in attenuation dip switches that allow you to manually attenuate (fine tune) the repeater's Uplink and Downlink channels in 1db increments up to 31dB, using color changing LED's as a status indicator. These Alarm LED's are used as a guide to prevent your installation from re-producing errors due to excessive input signal strength if a pre-amp is used, or from signal oscillation due to the indoor antenna and outdoor antenna being too close to each other, which can have adverse effects on a base station and greatly impede system performance. 

A Network Safe / MUTE™ feature comes standard with this repeater to protect the cellular network. In short, the repeater will stop transmitting if any errors or signal oscillation is detected within 2-4 sec of detection. It will cycle for 30 sec then attempt to transmit again. If no adjustment in gain has been made to correct the error within the 30 sec MUTE cycle, the system will again shut down after 5 sec. It will run this sequence for a total of 3 times and then shut down completely.  Power cycling  the unit will reset this sequence.

This repeater is designed to be transparent to the network and will therefore support the same number of calls the serving sector of the BTS the donor antenna is aimed at.
