Curtiss-Wright Controls Defense Solutions' new CHAMP-WB family of rugged OpenVPX modules will include the TDAC-25 10-bit 25 GS/s digital-to-analog converter (DAC) ASIC. The TDAC-25 delivers up to -60 dBc of dynamic range and enables direct-generation of wideband signals, and is claimed to be the world’s fastest commercially available DAC technology. The company claims the TDAC-25 significantly increases the wideband RF data conversion performance for signal generation in commercial communications development applications.
Curtiss-Wright will first deliver the TDAC-25 on the recently announced CHAMP-WB-DRFM card set featuring the Tektronix 12.5 GS ADC/DAC-based TADF-4300 module. The TADF-4300 was jointly developed by Curtiss-Wright and Tektronix for use with the CHAMP-WB Xilinx Virtex-7 based 6U VPX card. The first announced member of the CHAMP-WB family, the CHAMP-WB-DRFM card set, deploys the TDAC-25 as part of an ADC/DAC combination with maximum module speed rated at 12.5 GS/s.
Curtiss-Wright plans to provide the TDAC-25-based DAC-only configuration on the forthcoming CHAMP-WB-AWG (Arbitrary Waveform Generator) card set, which promises to establish a new standard of performance and precision for direct generation of wideband RF signals, reducing the need for additional frequency conversion blocks.
