Digital IF: Technology Readiness Level CERDEC FAST Prototypes
Underlying Technology A/D, D/A, DSP, FFT, IP, Ethernet SNMPv1, SNMPv3, XML over IP, secure XML over IP
Technology Readiness Level Description
6. System/subsystem model or prototype demonstration in a relevant environment
Representative model or prototype system, which is well beyond the breadboard tested for TRL 5, is tested in a relevant environment. Represents a major step up in a technology's demonstrated readiness. Examples include testing a prototype in a high fidelity laboratory environment or in simulated operational environment.
Technology Readiness Level Description
8. Actual system completed and 'flight qualified' through test and demonstration
Technology has been proven to work in its final form and under expected conditions. In almost all cases, this TRL represents the end of true system development. Examples include developmental test and evaluation of the system in its intended weapon system to determine if it meets design specifications.

Digital IF: Enterprise Terminal Cost-Benefit
modems through block conversion L-Band IF Digital IF
Modems, 192 each $1,920,000 $ 960,000
Switch Matrix Combiner/Divider, 192x24 $3,200,000
Ethernet Switch, 288 x 288, 2 each $ 200,000
Digital Combiner/Dividers, 24 each $ 240,000
Digital / L-band Converters, 24 each $ 600,000
Coax Cables, L-band Amps $ 50,000 $ 50,000
Totals, modems to RF $5,170,000 $2,050,000 Assumptions
Significant components only Modem cost is half Modem conversion cost is trivial Ethernet Switch – layer 1 – quoted Digital combiner/dividers $10k / aggregate Digital / L-band Converters $25k per pair All are conservative
Conclusions Save > $3M / terminal, incl modems Save > $1M / terminal sinking modem cost Conservative; yet to consider
