Description
The RDA5850 is a single-chip broadcast FM transceiver with a fully integrated synthesizer, IF selectivity, and MPX decoder. It supports multi-interface and requires the least external components, making it very suitable for portable devices with its small 4x4mm package size. The RDA5850 features a powerful low-IF digital audio processor that provides optimum sound quality under varying reception conditions. It also uses RDA patented dual synthesizers and an all-digital transmit structure for excellent transmission performance and agility. The RDA5850 supports a frequency band of 65M~115M and integrates 4K memory, making it suitable for use in simple wireless control appliances such as toys.
