DC~Notch Band~1GHz

A Notch Filter, also called a Band Stop Filter or Band Reject Filter, is a passive RF component that blocks a specific frequency band while allowing all other frequencies to pass. At Concept Microwave, our notch filters are engineered for high-Q narrowband suppression, precisely eliminating interfering carriers, harmonics, or unwanted signals with minimal impact on adjacent frequencies.
