Bandpass filters are used in both wired and wireless communications systems, sensor applications, instrumentation, medical applications, and many others. When it comes to these types of applications, ...

A tuned circuit formed by a capacitor and an inductor is a familiar enough circuit, and it’s understood that it will resonate at a particular frequency. As that frequency increases, so the size of the ...

Why a tunable GHz-range filter is needed. How a new approach to devices based on YIG and magnetic spin waves offers a much smaller and lower-power solution. How the new device was implemented along ...
