Rockwell Collins Filter Products specializes in designing mechanical filters to meet your unique and evolving requirements. We produce two different types of mechanical filters. For frequencies between 100 kHz and 700 kHz, we create filters made from rods resonating in a torsion mode. For frequencies below 100 kHz, we use flexure mode bar resonators. Our filters can achieve bandwidths from 0.05 to 5 percent. Whatever your filter needs are, Filter Products can customize designs to meet them.
