The RF1419D is a surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in the 402-405 MHz band. This filter is ideal for short range wireless medical data applications where small size and low power consumption are required features. Receiver designs using this filter include superhet, direct conversion or superregen. Murata's advanced SAW design and fabrication technology is utilized to achieve high performance and optimum loss with simple external impedance matching.

Key Markets Healthcare | Medical
Key Applications Cardiac Pacemakers | Cardiac Defibrillators | Neuromuscular Stimulators
Applications Characteristics For medical implant devices with receivers that require rejection of strong out-of-band signals: | - That are non-life sustaining operational elements | - Operating under FCC Part 95 | - That require rejection of strong out-of-band signals (needing, for example, typical out-of-band rejection of 50 dB); | - That may require special rejection at -10.7MHz for local oscillator rejection and special rejection at -21.4MHz for image spurious response for typical superhet receivers.
