Profile: RFM is engaged in the design and manufacture of low-power radio frequency (RF) products using surface acoustic wave (SAW) technology. We provide discrete SAW resonators in frequencies ranging from 300 MHz to over 1 GHz. They are designed to be the frequency control element in transmitters and receiver local oscillators. Their use allows reduced receiver bandwidths. 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 & group delay ripple, small size and high out-of-band rejection.
