Industry’s First COTS Mezzanine with 64 GSps ADC/DAC Sample Rates Is Introduced by Annapolis MicroSystems

Annapolis Micro Systems announced the availability of the industry’s first COTS FMC+ Mezzanine Card to feature Jariet Technologies’ Electra-MA chip with 64 GS/s, 10-bit ADC, and DAC capability. It is targeted at demanding applications requiring direct sampling frequency coverage anywhere from 0.1 to 36 GHz, and/or wide instantaneous bandwidths.

This breakthrough, direct sampling Jariet transceiver performs frequency conversion and filtering in the digital domain, eliminating the need for costly analog frequency conversion. The WILD FMC+ DME1 ADC & DAC Card thus provides an unprecedented level of performance and integration for RF and microwave systems:

• 2-Channel, 40 to 64 GSps, 10b ADC
• 2-Channel, 40 to 64 GSps, 10b DAC

It has a usable analog bandwidth of 36 GHz and a maximum instantaneous bandwidth of 6.4 GHz on both channels simultaneously. All transceiver channels feature onboard digital downconverters (DDCs) and digital upconverters (DUCs), including sub-band channelizers for dynamic frequency selection.

“We are excited to be the first company to use Jariet’s Electra-MA transceiver in a COTS mezzanine,” said Noah Donaldson, Annapolis Micro Systems Chief Technology Officer. “This daughter card integration allows for maximum flexibility of use, and for significantly higher performance than adding the transceiver directly to a baseboard.”

“The DME1 WFMC+ from Annapolis Micro Systems represents a significant milestone in the maturity of direct sampling transceiver products,” said Craig Hornbuckle, Chief Technology Officer of Jariet Technologies. “While ADC and DAC prototypes sampling at tens of Gigasamples per second have existed in the lab for a few years, the technology has finally reached the level of maturity necessary to practically deploy it for the warfighter. Flexible spectrum access from VHF through Ka-band will be a gamechanger in the competition to control the electromagnetic spectrum.”

The DME1 is available for use with 3rd party FMC+ baseboards or with Annapolis’ WILDSTAR 3U OpenVPX Baseboards (one WFMC+ mezzanine site) or 6U OpenVPX Baseboards (two WFMC+ mezzanine sites). Annapolis WILDSTAR Baseboards utilize up to three high-performance FPGAs.
