DSP & Signal Processing Job opening

Due to our continuing success with the KRM-4 RFSoC product line and increasing project load, we are actively looking for an FPGA developer with experience in signal processing for telecommunications and radar applications. Read more [...]

KR keeps growing

It is hard to believe that almost 5 Years have elapsed since we moved to our “new” location at Ackerstrasse 30 in Basel. At that time, I could not imagine that we would fill and [...]

Testing KR modules beyond limits

In April 2021 we started to subject our KRM-4ZUxxDR modules to an extensive temperature test on a KRC-4700 test carrier, extended outside of our temperature specification of 0 °C to 70 °C for a commercial [...]


How to Choose an RF SoM for Best Performance

RFSoMs (Radio Frequency converter enabled Systems on Module) are convenient, take care of all the RFSoC's complex power requirements and memory interfaces, are typically compact, and save months, if not quarters in development time. But [...]

KR turns 20: Revisiting a Favorite Project

KR turns 20 this year -- a good time to pause and reflect on some of the milestones along the way. One of our favorites remains the robots project for the Museum of Mathematics in [...]
