Originally developed for the JBREWS program, the DGBR Series of spread spectrum radios and radio boards are designed to meet the rigorous demands of military and government users worldwide. Available as OEM board level radios or as packaged modems in rugged or waterproof enclosures, the radios operate over a 225 to 400 MHz frequency range. The radios may also be programmed to operate over any portion of this range to avoid interference with other radio systems in the area of operation.
 
With an advanced frequency hopping technology, a 4 watt RF output and a sensitive, wide dynamic range front end, the DGBR radios provide reliable data communications even in the most adverse environments. Error-free data transmission is assured with the proprietary 32-bit CRC error check, automatic acknowledgment and data retransmission. The DGBR radios share other powerful features with our popular 900 MHz and 2.4 GHz products, including 115.2 Kbps throughput, single radio repeater and slave/repeater modes.
