Product brief
Product brief
FWBD-2901 has 802.11ac 2×2 radio supporting up to 866.7 Mbps data-rate
The FWBD-2901 is consisting of two major sections,
QCA9882 (Radio)
Digital section and Analog Section
The Qualcomm Atheros QCA9882 s a highly

QCA9557 (CPU)
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. It includes a MIPS 74Kc
processor, one PCI Express 1.1 Root Complex and
one PCI Express Root Complex/Endpoint interfaces,
one RGMII interface, one SGMII interface, two USB
2.0 MAC/PHY, and external memory interface for
serial Flash, DDR1 or DDR2, I2S/SPDIF-Out audio
interface, SLIC VOIP/PCM interface, two UARTs, and
GPIOs that can be used for LED controls or other
general purpose interface configurations. 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
Maximal Likelihood (ML) decoding, Low-Density
Parity Check (LDPC), Maximal Ratio Combining
(MRC), Tx Beamforming (TxBF), and On-Chip
One-Time Programmable (OTP) memory.
The QCA9557 PCIE Root Complex interface can be
used to connect to an endpoint such as the
Qualcomm Atheros single-chip MAC/PHY/radio for
dual concurrent WLAN applications. The QCA9557
supports booting from either SPI NOR or NAND
flash. If NOR flash is used as boot codestore, an
additional NAND flash device can still be
connected, for end-user multi-media storage and
other applications.
integrated wireless local area network (WLAN)
system-on-chip (SoC) for 5 GHz 802.11ac or 5 GHz
802.11n WLAN applications. The QCA9882
integrates an on-board CPU for low-level setup of
WLAN physical layer (PHY) and RF to offload the
host processor for other tasks. It enables
high-performance 2x2 MIMO with three spatial
streams for wireless applications demanding the
highest robust link quality and maximum
throughput and range.
The QCA9880 supports up to two simultaneous
traffic streams integrating two Tx and three Rx
chains for high throughput and extended coverage.
Tx chains combine PHY in-phase (I) and quadrature
(Q) signals, convert them to the desired frequency,
and drive the RF signal to multiple antennas. Rx
chains use an integrated architecture. The
frequency synthesizer supports 1-MHz steps to
match frequencies defined by IEEE 802.11a/n/ac
specifications. The QCA9882 supports frame data
transfer to and from the host using a PCIE interface
providing interrupt generation and report
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
QCA9882 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
QCA9882 BBP integrated module.
