ECHO Microwave is developing another filter lines such as Thin-Film
and substrate Filters, especially for high frequency bands up to
40GHz. We already have good filter solutions as cavity, ceramic, LC
and SIW, but we expect the thin-film and substrate filters to be good
choices for your high frequency application such as Military, Radar,
Aerospace and Satellite Communication System.
Thank you.
