Crystal filter has multiple notches

Designed to enhance sound reproduction in such applications as satellite communications, radar, cellular phone infrastructure, microwave transmission, and precession instrumentation, the Model RNXF-37-15 notch crystal filter reduces the gain of narrowband frequency spectra, leaving the surrounding audio unaffected. Uniquely, the RNXF-37-15 allows between two and five notches, with attenuation down to 70 dB and very low ripple.

Key specifications include a frequency range of 1 MHz to 60 MHz, input and output impedence of 50 or 75 Ω, dimensions as small as 36 x 23 x 12 mm with optional SMD packaging. Output is through a pin or a BNC/SMA Connector.
