Direct Digital Radio Frequency (RF) Conversion Digital Radio Frequency Memory (DRFM)
RFSS’ Direct-to-Digital DRFM (D2 DRFM) technology obviates the need for RF signal translation that are typically necessary to digitize and reconstruct RF signals, by using a novel D/A scheme that mimics existing A/D technology. RFSS is a leader in the design, development, and manufacture of complex hardware-in-the-loop radar simulation equipment and Digital RF Memory (DRFM) jamming systems for defense and aerospace industries worldwide. The benefits include a sizable reduction in SWAP-C, reduced system latency; and dramatic improvements in reliability, bandwidth, and capability up to 20 GHz. These would address Defense applications like UAV’s, fighter aircraft, and small jammer pods. In particular, PMA-272’s ALQ-167 jamming pods would enjoy the benefits of the D2 DRFM During Phase II RFSS was able to prototype and validate the interfaces through emulation and simulations on representative hardware. We also identified a lower risk approach utilizing COTS FPGA boards with industry standard mezzanine interfaces such as a high density FMC mezzanine modules, and better components that will support the higher speeds and data rates including DDR4 memories and DDS clock and multiplier schemes. By working down these risks, we see that we are much closer to a field ready unit than previously envisioned. RFSS is looking to have this technology integrated into AEA systems that are highly sensitive to SWAP-C and reliability, like UAV’s and small electronic warfare pods. RFSS would likely provide these to a prime contractor for an AEA, under a subcontract that would include some NRE.
