  • How to select a space-grade switching regulator
  • Thanks for another great post - I wish you would reveal the parts to solve my current procurement predicament. I totally get what you say about consistency when providing radiation hardness data and I waste a lot of time chasing this sort of information which is often incomplete. Cheers, Dave

  • Spacecraft data handling using ARM-based processors
  • Thanks for the article, 90 billion is a lot of chips and I wasn't aware these are being used in so many safety critical applications. I know my phone contains many ARM cores. The hardened Vorago device could be an alternative to a space FPGA in some cases. Dave.

  • Wideband testing of satellites
  • I've had lots of issues with I/Q mismatch when using analog up convertors and its interesting to read that AWGs can do this digitally and more precisely. Nice article.

  • IBIS-AMI for rocket scientists
  • Rajan, thanks for another interesting post. I havent used IBIS-AMI before but will do soon to verify 3.125 Gbps links between FPGAs and boards. This tutorial is timely for me. I am interested in your space FPGA course, Dave.

  • RF impedance matching for rocket scientists
  • Rajan, Thanks for taking time to write another interesting post. Very interesting indeed and it explains why we are losing power and seeing ripple. Enjoyed the video and I want one of your pens. Dave

  • Decoupling for rocket scientists, part 1
  • Its interesting to understand how to estimate the amount of decoupling and the number of caps that will be required, I always struggled with this. Thanks for taking the time to write this post and look forward to the next instalment. Dave.

  • Introducing the world’s first 28nm semiconductor for space
  • Wow, an impressive FPGA which will give the space industry comparable performance to some of the latest commercial devices. Thanks for taking the time to write another great post and look forward to reading the upcoming posts in the tutorial series, Dave.

  • Are you bored with your board?
  • thanks for another interesting and insightful post, I hadn't realised that the density of the weave could affect performance as you have described. Dave.
