Si4738/39 AM/FM/WB Radio Receivers

Si4738/39 devices are the industry's first fully integrated, 100% CMOS AM/FM/WB and FM/WB radio receivers, providing space savings and low power consumption necessary for portable devices while delivering high performance and design simplicity for all AM/FM/WB solutions.  

Leveraging our proven and patented digital low intermediate frequency (low-IF) receiver architecture, Si4738/39 devices deliver superior RF performance and interference rejection in both AM and FM bands. The high integration and complete system production test simplify design-in, increase system quality, and improve manufacturability. With unmatched integration and PCB space savings, Si4736/37/38/39 ICs require just two external components and less than 15 mm2 of board area, excluding the antenna inputs.
