Title: Synthesis and Tuning of Modern Microwave Filters

Date: November 8th, 2012

Time: 8am PT, 11am ET, 5pm CET

Abstract:
The first part of this webinar focuses on filter synthesis. Starting with the classic coupling matrix approach in which the matrix coefficients determine the filter topology, we will focus on the conversion of this matrix into a 3D model in CST MICROWAVE STUDIO® (CST MWS). We will demonstrate the new link between CST MWS and the filter synthesis tool Nuhertz as well as a specialized built-in macro for automatic band-pass filter synthesis and construction.

The second part of the webinar will discuss numerical approaches to the simulation and tuning – direct 3D simulation, space mapping techniques, group delay, and inverse Chirp-Z transformation – that can be applied within CST STUDIO SUITE. Multiphysics modeling for thermal and mechanical analysis of high power filters, as well as multipacting in space-borne components, will be briefly discussed. Real world design examples will be used throughout.

Presenter bio:
Vratislav Sokolholds an M.Sc. and Ph.D. in radioelectronics from the Czech Technical University in Prague. He was a Post-Doctoral Research Associate with Cork Institute of Technology in Ireland where he dealt with an ultra-wideband transceiver. His activities are focused on microwave circuit design and modeling using electromagnetic field simulators and precise microwave measurement and calibration. He joined CST AG in 2006 where he is an application engineer.
