Katsman, Vladimir SBIR Phase I Award, July 2022

To enhance the design of backend spectrometers included in NASArsquo;s microwave radiometers, ADSANTEC will develop a wide bandwidth (gt;30 Ghz) radiation-hardnbsp;digitizer with more than 6 effective bit resolution utilizingnbsp;a space qualified US located semiconductor foundry. The scalable digitizer with a sampling rate up to 25 Gs/snbsp;will be able to directly interface to space-qualified Xilinx Versal FPGAs using a patented FPGA compatible reverse pseudo-synchronization algorithm and rad hard SPI control interface.nbsp;nbsp;nbsp;The proposed FPGA interface integrates the proprietary synchronization protocol that minimizes the data transmission overhead. The utilization of advanced a wide temperature range (up to -200 Degree C) SiGe 9 HP technology developed by IBM will help to achieve the wide temperature range of operation and low power consumption of the digitizer, which will incorporate internal already proven extremely low noise clock source. The companyrsquo;s proprietary space qualified packaging will enable fabrication and testing of the prototype to TRL 8 by the end of Phase II.nbsp;The developed digitizer will support the advanced requirements of NASArsquo;s microwave radiometers development, next Generation of Laser Communication Relay Demonstration program, DoDrsquo;s program for GPS Block IIIF payload development, and numerous worldwide radio astronomy programs such as SKA and ALMA. ADSANTEC offers more than 200 space qua Application Specific Integrated Circuits including ADC ASNT 7113 A developed during NASA SBIR Programnbsp;in 2012 and commercially available as a space qualified ASIC.nbsp;
