WILD FMC+ DME1 ADC & DAC – WWDME1

The WILD FMC+ DME1 ADC & DAC is the industry’s first COTS product to feature 64 GS/s, 10-bit ADC and DAC Direct RF capability. The SOSA-aligned DME1 integrates a Jariet Technologies transceiver and is targeted at demanding applications requiring direct sampling frequency coverage anywhere from 0.1 to 36 GHz (VHF through Ka-band), and/or wide instantaneous bandwidths.

Want the same Direct RF capability in a 3U VPX form factor? See the WILDSTAR 3AE1 3U OpenVPX Board.

The WILD FMC+ DME1 ADC & DAC allows sample rates as high as 64 GSps and provides up to four channels each (6U) of high speed, precision analog-to-digital and digital-to-analog outputs for a compatible motherboard.

It has a usable ADC/DAC analog bandwidth of 20/36 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.
