RFM designs and manufactures bandpass filters, delay lines, and notch filters, for a wide range of wireless telecommunication and data communication applications. We provide filters from 61 MHz to more than 1.6 GHz in surface-mount, dual-in-line (DIP) and TO39 packages. Our filter products offer a wide range of bandwidth, low insertion loss, low amplitude and group delay ripple, small size and high out-of-band rejection. In addition to our standard product offering, RFM provides custom filter design services for high volume applications.
