AT1846SD
Description
The AT1846S 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 AT1846S has a powerful digital signal processor, which makes it have optimum voice quality, flexible function options, and robust performance under varying reception conditions.
The AT1846S 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 ponents and eliminates the plicated design of sensitive RF circuits on PCB.
