Practical Aspects of Microwave Filter Development

The design and development of microwave filters and networks proceeds from strong theoretical underpinnings, with readily-available theory (and software) covering such diverse areas as circuit topology, electromagnetic radiation and coupling, thermal and mechanical properties of materials, mechanical resonances and finish characteristics. However, practicality requires consideration of design and production economics, including not only labor costs, but skilled labor availability. Modern simulation tools can be applied to prediction of performance, and can include not only electrical parameters and component tolerances, but the effect of ambient operating environment and projected production delivery rates. The art of filter design requires time for mastery.
