Si4707

Si4707 Weather Band Radio Receiver

Si4707 ICs are the industry's first weather band (WB) radio receivers to include a specific area message encoding (SAME) processor. Leveraging our patented Si4700/01 FM tuner's digital low intermediate frequency (low-IF) receiver architecture, Si4707 devices deliver superior RF performance combined with sophisticated digital processing to yield best-in-class audio quality and SAME data sensitivity. Si4707 weather band receivers provide the space savings and low-power consumption necessary for portable devices while delivering the high performance and design simplicity desired for all weather alert radios. 

Offering unmatched integration and PCB space savings, Si4707 ICs require only one external component and less than 15 mm² of board area.  Available in a tiny 3 mm x 3 mm QFN package, Si4707 eliminates the need for a front-end tuner IC, external ADC, DSP, RAM and numerous discrete components found in traditional SAME weather band radios. The high integration and complete system production test simplifies design in, increases system quality and improves manufacturability.
