Greetings from Comtech EF Data – This e-Newsletter features the technical & business case for deploying the bandwidth-efficient CDM-Qx with DoubleTalk™ Carrier-in-Carrier® plus the High-Power Outdoor Amplifier, and solutions for optimizing communications for government & military applications.

     
ST Teleport, a full-service satellite communications solution provider conducted performance measurement testing of the CDM-Qx Satellite Modem with the DoubleTalk™ Carrier-in-Carrier® technology. The purpose was to study the bandwidth and power efficiency of the CDM-Qx with DoubleTalk Carrier-in-Carrier (CnC) in a SCPC link. The test results showed that a bi-directional SCPC link with 512 kbps data rate will use 921 kHz of satellite bandwidth without CnC. With CnC, it used 453 kHz which represents 50% bandwidth savings.

Offering the same superior performance as our indoor amplifiers, the High-Power Outdoor Amplifier (HPOD) series of C-, X- and Ku-Band Solid-State Power Amplifiers provide a cost effective, more reliable replacement for TWT amplifiers in satellite communications terminals.  We offer field replaceable power supplies, effectively minimizing a limiting MTBF factor in electronic equipment. The design provides conservative thermal performance using forced air-cooling for extreme environments. These are available with an internal reference and require no DC power from the modem, greatly simplifying multi-carrier and redundant operation.  [See Datasheet]
