The AT6558R-5N32 with RF Transceiver ICs QFN-40 RoHS by ZHONGKEWEI is a 40-pin, RoHS-compliant, Quad Flat No-leads (QFN) Radio Frequency Transceiver Integrated Circuit (RFIC). It is designed for communications equipment that requires a media access controller (MAC) for short range radio link, such as Bluetooth, WLAN, and ZigBee applications. The device has a digital baseband processor and a RF transceiver integrated into the same package, all in a low power CMOS process. It is capable of supporting multiple modulation formats, including GFSK, DSSS, and MSK. The device also features integrated power saving modes, on-chip antenna switching, and an RF transceiver for operation in the 2.4 GHz ISM band. The AT6558R-5N32 with RF Transceiver ICs QFN-40 RoHS by ZHONGKEWEI is an ideal choice for Bluetooth, WLAN, and ZigBee applications.
