EM Simulation Tool Used to Develop High-Performance Custom FiltersSource: CST of America, Inc.
Test Equipment Plus, Inc. provides service and support for the used test and measurement equipment market. One of the many product lines they support are Signal Hound® spectrum analyzers. The first prototypes of the analyzers were in need of a spectral filtering solution to improve their overall performance. This case study describes how Test Equipment Plus utilized the CST Microwave Suite EM simulation tool to produce virtual prototypes of the analyzers with buried printed filters instead of the problematic discrete filters they were using before.
