Welcome
We live in a wireless world. Cellular phones, 2G, 3G, LTE, Satcom & broadcast, digital TV & Radio and the list goes on. All these systems use various radio frequency ranges, various parts of a scarce radio spectrum. All of these systems incorporate various types of filters as essential parts. Without these they simply could not work. Your access to this website probably involved satellite communication. Satellites cannot work without elaborate filter multiplexers which allow a number of transponders to share the same antenna.
This BBC news item of June 3rd 2011 shows how important filters still are in today’s wireless world.
Experts in the field of rf & microwave filter technology are rare and few universities teach courses on filter theory. At the same time it is an exciting and challenging field of rf engineering & design. Even though I have worked in this field for many years I still enjoy its challenges and the opportunities to do new things. This website is intended for creating interest in the highly specialised field of filters, provide some help for beginners and students and to complement existing literature on the subject. Eventually there is a certain amount of math involved, but if you chose to master the field of filter theory and design, you will find access into other fields of rf engineering relatively easy and your analytic skills will definitely improve.
