  • Description

    The RDA5872 is a single-chip broadcast FM transceiver with fully integrated synthesizer, IF selectivity, and MPX decoder. This CMOS IC chip supports multi-interface, requiring the least external components. It has a small package size of 4x4mm and is completely adjustment-free, making it highly suitable for portable devices. The RDA5872 also features a powerful low-IF digital audio processor, providing optimum sound quality under varying reception conditions. With RDA patented dual synthesizers and an all-digital transmit structure, it offers excellent transmission performance and agility. The RDA5872 supports a frequency band of 65MHz to 115MHz and integrates 4K memory, making it ideal for simple wireless control appliances such as toys.
