Techniques, methods & infrastructure
Our RF lab is equipped with three network analyzers (Agilent E5071C, Agilent E6061B, HP 3577A), oscilloscopes, soldering stations, and a variety of mechanical tools.
For 3D electromagnetic simulations of RF coils, software packages Remcom XFdtd and Agilent ADS running on a dedicated workstation with four NVIDIA Tesla C2070 GPUs are available.
