BT/ZB/ 802.11 n/ac Dual-band Transceiver RS8112


The RS8112 is an ultra low power and high performance RF transceiver for Bluetooth, zigbee and WLAN IEEE 802.11 a/b/g/n/ac applications. It supports simultaneous BT/ZB and WLAN operation and has an integrated high-efficiency 2.4GHz & 5GHz CMOS PA with integrated Baluns for both bands in transmit mode. It has an analog interface to the SoC with integrated MAC/BBP, making this an ideal companion RF to Redpine’s 1x1 Wi-Fi Technology.
