CDM-Qx Satellite Modem	Revision 5
Introduction	MN/CDMQx.IOM

1.5L-Band

Fully configured, the modem will meet or exceed all of the applicable requirements in IESS-315 and is available with a full range of industry standard digital interfaces. The modem expands the capabilities into L-Band frequencies. Utilizing advanced technology and proprietary digital signal processing techniques, the design eliminates analog circuitry to perform modem signal processing, resulting in higher reliability and reduced packaging size.

1.6Compatibility

The Modem is backwards compatible with a number of Comtech EF Data CDM modems, SDM modems, and SLM modems.
