Description :

RDA1846 SINGLE CHIP TRANSCEIVER FOR WALKIE TALKIE 1. General Description GPIO0 GPIO1 GPIO2 GPIO3 GPIO4 GPIO5 GPIO6 RFIN Rev.1.2–Dec.2009 The RDA1846 is a highly integrated single-chip transceiver for Walkie Talkie applications. It totally realizes the translation from RF carrier to voice in the RX path and from voice to RF carrier in the TX path, requiring only one micro controller. The RDA1846 has a powerful digital signal processor, which makes it have optimum voice quality, flexible function options, and robust performance under varying reception conditions. The RDA1846 can be tuned to the worldwide frequency band for Walkie Talkie from 400MHz to 500MHz and especially from 134MHz to 174MHz which meets the frequency band of weather broadcast. The transceiver uses the CMOS process with a package size of 5X5mm. By virtue of its high integration, it requires the least external components and eliminates the complicated design of sensitive RF circuits on PCB. 1.1 Features    […]
