So, any recommendations? Use student versions of the commercial packages? Cobble together (or find) useful pieces from the web? An integrated package would be ideal but I don't hold out too much hope. You daily tasks will consist of leading and executing technical. Design distributed-element microstrip filters with low-pass or band-pass response, and stubs, stepped impedance or interdigital topology. You are an expert for techno-economical aspects in your own area of responsability. I haven't found much open source filter synthesis software beyond simple ham radio oriented material. As an RF Filter Mechanical Design Engineer, you will have the senior responsibility for specifying, planning, reporting, designing and reviewing within your technical area (e.g. Less expensive options include LTSpice and the QUCS open-source circuit simulator. On the other hand, these are the tools they will likely use in a professional working environment. Then request free inductor samples with the push of a button. You can create elliptic low pass filters using actual Coilcraft inductance values, not just ideal components. On one hand, I hate to give the students the idea that they need to buy a $10k+ software package to perform filter synthesis and circuit analysis when there are cheaper tools available. Coilcraft LC Filter Designer Software Coilcraft has teamed with Nuhertz Technologies to offer this customized version of their powerful FilterSolutions software. I believe I can get student licenses of either Keysight GENESYS or Microwave Office from AWR, although I haven't yet looked into it. I'm looking for recommendations for both the filter synthesis and circuit analysis apsects of the lab. We use Rigol DS815 spectrum analyzers with tracking generators as our network analyzers to test/tweak our filters after we build them. All - I teach a lab-based RF course and am thinking about adding a section on buidling and evaluating RF filters.
