Quarter-wave resonant cavity filters are used in many RF applications in land mobile radio. For instance, they are used in duplexers for repeaters, in transmitter combiners, and as filters for ...

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, ...

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 ...

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 ...

Certain applications such as satellite communications require very severe filtering functions. Low passband loss may be combined with extreme selectivity and group delay linearity requirements. In ...
