SOFTWARE
COMSOL Multiphysics®
The RF Module, an add-on to the COMSOL Multiphysics® software, analyzes RF, microwave, mmWave, and THz designs in various multiphysics scenarios. The RF Module optimizes impedance matching and far-field gain pattern of antennas, and insertion loss and coupling effects of passive circuits in the application area of 5G and IoT. The EM simulation can be extended to perform multiscale modeling with ray tracing. It is possible to include other physics phenomena, such as temperature increase with absorbed radiation, and structural deformation induced by heat expansion.

3D Geometry Model
Modelithics has introduced a new set of full-wave EM capable 3D geometry models for Coilcraft’s 0603CS surface mount air coil inductor series. The model is now available within Modelithics COMPLETE+3D Library for ANSYS HFSS™. Individual 3D models are available from 1.6 to 390 nH and are validated against multi-substrate measured S-parameters through 20 GHz and equivalent series resistance (ESR), as well as against the corresponding Modelithics CLR Global Circuit model. As Coilcraft is a Sponsoring Modelithics Vendor Partner (MVP), free 90-day trials of all available Modelithics Coilcraft models are available to qualified customers by request.

COMMUNICATIONS
Ultra-Performance Receiver
The SIR-4000 uses the latest DSP technologies to meet the specific needs of the end user. Elcom recognized that in today’s real-time threat environment one size does not fit all. The company’s goal was to provide the end user a tool that could cover a wider frequency range (up to 40 GHz) and instantaneous bandwidth (up to 2 GHz) critical to RWR applications.
