Description
The RDASW62 is a highly integrated single-chip transceiver for Walkie Talkie applications. It is designed and manufactured by RDA Microelectronics Inc. The chip is capable of realizing the translation from RF carrier to voice in the RX path and from voice to RF carrier in the TX path with the support of only one microcontroller. It comes equipped with a powerful digital signal processor that ensures optimum voice quality, flexible function options, and robust performance under varying reception conditions.
