General product information: The B2, B5 is a high performance outdoor point to point device specifically designed for optimized performance at 2.4GHZ, and 5GHz, respectively. It is built around the Atheros AR2315 SoC which integrates a 180MHz MIS4KC processor, MAC/BB functionality and RF operation on a single chip. The AR2315 is connected to FLash, RAM, a 40MHz crystal. Its MII interface is connected to a Ethernet hy and transformer to a RJ45 jack. An RF front-end connects to the chip which includes a power amplifer, low-noise amplifier, and TX/RX switch. The B2 contains a power control feedback mechanism which works with calibration stored in the EEROM to ensure proper predefined output powers for different channel frequencies and data rates.
