1. General Description

AzureWave Technologies, Inc. introduces the pioneer of the IEEE 802.11 a/b/g/n/ac WIFI with

Bluetooth 4.2 combo M.2 module --- AW-CM308NF. The AW-CM308NF IEEE 802.11 a/b/g/n/ac PCIE
WIFI with Bluetooth 4.2 combo M.2 module is a highly integrated single-chip MIMO (Multiple In, Multiple

Out) wireless local area network (WLAN) solution to let users enjoy the digital content through the latest

wireless technology without using the extra cables and cords. It combines a WLAN MAC, a 2T2R

capable WLAN baseband, and RF in s single chip. It enables a high performance, cost effective, low

power, compact solution that easily fits onto the PCI Express and USB M.2 module.

The AW-CM308NF baseband implements Multi-user Multiple Input, Multiple Output (MU-MIMO)

Orthogonal Frequency Division Multiplexing (OFDM) with two transmit and two receive paths (2T2R).
Features include two spatial stream transmissions, short Guard Interval (GI) of 400ns, spatial spreading,

and support for variant channel bandwidth. Moreover, AW-CM308NF provides one spatial stream space-

time block code (STBC), Transmit Beamforming (TxBF) and Low Density Parity Check (LDPC) to extend
the range of transmission. At the receiver, extended range and good minimum sensitivity is achieved by

having receiver diversity up to 2 antennas. As the recipient, the AW-CM308NF also supports explicit

sounding packet feedback that helps senders with beamforming capability.

For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying
(CCK) and OFDM baseband processing are included to support all IEEE 802.11b, 802.11g and 802.11a

data rates. Differential phase shift keying modulation schemes, DBPSK and DQPSK with data

scrambling capability are available, and CCK provides support for legacy data rates, with long or short
preamble. The high speed FFT/IFFT paths, combined with BPSK, QPSK, 16QAM, 64QAM and 256QAM

modulation of the individual subcarriers, and rate compatible coding rate of 1/2, 2/3, 3/4, and 5/6, provide

up to 866.7Mbps for IEEE 802.11ac MIMO OFDM.

The RTL8822BE-CG builds in an enhanced signal detector, an adaptive frequency domain equalizer,
and a soft-decision Viterbi decoder to alleviate severe multi-path effects and mutual interference in the

reception of multiple streams. For better detection quality, receive diversity with Maximal-Ratio-Combine

(MRC) applying up to two receive paths is implemented. Robust interference detection and suppression

are provided to protect against Bluetooth, cordless phone, and microwave oven interference.

Receive vector diversity for multi-stream application is implemented for efficient utilization of the MIMO

channel. Efficient IQ-imbalance, DC offset, phase noise, frequency offset, and timing offset

compensations are provided for the radio frequency front-end.
