Telecommunications engineer Israel Arnedo Gil of the UPNA has proposed in his doctoral thesis a new method to design microwave filters. These filters allow to improve the circuits operating between 1 GHz and 300 GHz, that is, microwave and millimeter wave circuits. These circuits have multiple applications: radars, information transmission (telephony, television, internet or data), satellite communication, wireless communication systems, etc.

In short, it is necessary to have filters for microwave circuits and millimeter wave, since the filters only let pass to the electromagnetic waves of a certain frequency, blocking the others.

Arnedo has improved the usual tools for filter design. It indicates that, in parallel with television, the filter synthesis techniques so far were black and white, and that the techniques developed by Arnedo have brought color.

Specifically, three areas of use have found the use of synthesis tools designed by Arnedo: in the space sector, that is, in communication between stations and satellites of the Earth, in the processing of radar signals (analog processing at high speed), and in the UWB technology (Ultra-Wideband) that is usually presented as a step forward in wireless communications.
