Ultra-Narrow L-Band Notch Filter, 1626MHz Center, ≥50dB Rejection for Satellite Band Protection

Concept model CNF01626M01626Q08A1 cavity notch filter is designed to provide exceptional protection for the critical 1626MHz satellite frequency band. Featuring an ultra-narrow notch band centered at 1625.98MHz ±25KHz and delivering ≥50dB of rejection, it is the definitive solution for eliminating strong interference in sensitive L-band satellite receive chains, particularly for COSPAS-SARSAT and other satellite communication systems.

Descripton

Notch filter known also as a band stop filter or band stop filter, blocks and rejects frequencies that lie between its two cut-off frequency points passes all those frequencies either side of this range. It is another type of frequency selective circuit that functions in exactly the opposite way to the Band Pass Filter we looked at before. Band-stop filter can be represented as a combination of low-pass and high-pass filters if the bandwidth is wide enough that the two filters do not interact too much.
