Six Channel 4.0/2.7/1.6GSps 12b ADC + Single Channel 12GSps 16b DAC WFMC+ – WDHM40

This rugged COTS mezzanine is optimized for high-performance operation in Wireless Communication, SATCOM Uplink/Downlink, RADAR, SIGINT, and EW.

Compatible with any WILDSTAR mainboard with two WFMC+ slots.

The Six Channel 4.0/2.7/1.6GSps 12b ADC + Single Channel 12GSps 16b DAC WFMC+ allows sample rates as high as 4.0GSps and provides six channels of high speed, precision analog-to-digital converter outputs for a compatible motherboard. It provides excellent analog performance with flexible high-precision trigger options.
