FWBD-2900 Product brief FWBD-2900 Product brief FWBD-2900 has 802.11N 2×2 radio supporting up to 300 Mbps data-rate The FWBD-2900 is consisting of two major sections, Digital section and Analog Section DIGITAL SECTION The section is made up of:  QCA9557  DDR2 Memory  Flash Memory  Power Supplies QCA9557 The Qualcomm Atheros QCA9557 is a highly integrated and feature-rich IEEE 802.11n 2x2 2.4/5 GHz System-on-a-Chip (SoC) for advanced WLAN AP/router platforms. The QCA9557 supports 802.11n operations up to 144.4 Mbps for 20 MHz and 300 Mbps for 40 MHz, and 802.11a/b/g data rates. Additional features include Low-Density Parity Check (LDPC), Maximal Ratio Combining (MRC), Tx Beamforming (TxBF), and On-Chip One-Time Programmable (OTP) memory. Power Supplies The 48V/0.5A DC input voltage is regulated to the following voltages for various purposes:  +1.2V for CPU core voltage  +3.3V for CPU, Flash, DDR  +5V RF ANALOG SECTION QCA9557 has integrated 2T2R MAC, BBP and RF. Each TX/RX chain only needs out-of-band rejection filters, Low noise power amplifier, Power amplifier and a switch to switch between transmission and reception mode. The switch and LNA on/off are controlled by the QCA9557 BBP integra
