3.0 DMD2050 Hardware

The DMD2050 is based on a two printed circuit card (minimum configuration) design with
additional optioned printed circuit cards available for additional features. The minimum
configuration consists of an L-Band/IF Assembly and a Digital Baseband Assembly. The optional
printed circuit cards include a Turbo Codec printed circuit card and one of several types of
Interface printed circuit card (refer to Appendix A). A block diagram of the DMD2050 is shown in
Figure 3-1.

3.0.1 DMD2050 L-Band/IF Printed Circuit Card

The L-Band/IF Printed Circuit Card consists of an analog modulation function, an analog complex
downconversion, and two wide-band digital synthesizers. The block diagram of the L-Band/IF
Assembly is shown in Figure 3-2.
