Test and Measurement

---

Through our partners at the University of Virginia, we provide on-wafer measurement capabilities from DC to 1THz, and waveguide coverage from 100GHz to 1THz. Equipment includes a number of vector network analyzers (up to 50GHz), a variety of millimeter-wave synthesizers (up to 50GHz), VNA extenders up to 1.1THz, power meters, and waveguide and coaxial components.

To aid in services we have created and continually maintain scikit-rf (www.scikit-rf.org), the the most popular python package for RF/Microwave engineering. Scikit-rf provides a modern object-oriented network analysis library with support for a wide range of calibration routines, instrument automation, and post processing features.

Microwave Design

---

Our team has extensive mmw and THz microwave circuit design experience. We employ a combination of finite element analysis and custom python-based infrastructure to achieve accurate designs efficiently. For computation and modeling, our partners at UVa have a number of high-performance computers and software packages including Ansoft’s High Frequency Structure Simulator, Agilent’s Advanced Design System, and Agilent’s Momentum.
