DMD1050TS Hardware

The DMD1050TS uses three printed circuit cards in its design. The standard configuration
consists of:

•

L-Band Assembly

•

Digital Baseband Assembly

•

FIPs 140-2 TRANSEC Security module

This configuration includes built in data interfaces and several software upgrade options.

A block diagram of the DMD1050TS is shown in Figure 3-1.
