Multi-band Radios

FM/AM, Shortwave, Longwave, Weather Band Radio Receivers. The Si473x, Si474x, Si4707, Si4831/35 and Si4840/44 devices are the industry's first fully integrated, 100% CMOS FM/AM/SW/LW and WB radio receiver ICs. Offering unmatched integration and PCB space savings, the Si47xx ICs require only two external components and less than 15mm² of board area excluding the antenna inputs.
