NOMVDIC ND10005 RF Module

General Description

• The RTL8821CU-CG is a highly-integrated IEEE 802.11 a/b/g/n/ac MAC/Baseband/RF WLAN and Bluetooth Baseband/RF single chip. For Wireless LAN (WLAN) operation, it supports
  1-stream 802.11ac solution with Multi-user MIMO (Multiple-Input, Multiple- Output) STA mode with USB2.0 network interface controller. For Bluetooth operation, it supports Bluetooth 2.1/4.2 with USB interface controller.

• The RTL8821CU-CG baseband implements multiuser Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) STA mode with one transmit and one receive path (1T1R). Features include one spatial stream transmission, short Guard Interval (GI) of 400ns, spatial spreading, and support for variant channel bandwidths. Moreover, RTL8821CU-CG provides one spatial stream Space-Time Block Code (STBC) and Low Density Parity Check (LDPC) to extend the range of transmission. As the recipient, the RTL8821CU-CG 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 802.11a, 802.11b and 802.11g data rates. Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling capability, are available. CCK provides support for legacy data rates, with long or short preamble. The high speed FFT/IFFT paths are combined with BPSK, QPSK, 16QAM, 64QAM and 256QAM modulation of the individual subcarriers. The compatible coding rate of 1/2, 2/3, 3/4, and 5/6 provides up to 433.3Mbps for IEEE 802.11ac with MIMO-OFDM.

• The RTL8821CU-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. 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.

• The RTL8821CU-CG supports fast receiver Automatic Gain Control (AGC) with synchronous and asynchronous control loops among antennas, antenna diversity functions, and adaptive transmit power control functions to obtain better performance in the analog portions of the transceiver.

• The RTL8821CU-CG MAC supports 802.11e for multimedia applications, 802.11i and WAPI (Wireless Authentication Privacy Infrastructure) for security, and 802.11n/ac for enhanced MAC protocol efficiency. Protocol efficiency is significantly improved by using packet aggregation techniques, such as A-MPDU with BA and A-MSDU. Power saving mechanisms, such as Legacy Power Save, U-APSD, and MIMO, can reduce the power wasted during idle time. They can also compensate for the extra power required to transmit MIMO-OFDM. The RTL8821CU-CG provides simple legacy and 20MHz/40MHz/80MHz co-existence mechanism to ensure backward and network compatibility.

• The RTL8821CU-CG Bluetooth controller complies with Bluetooth core specification v4.2, and supports dual mode (BR/EDR + AMP + Low Energy Controllers). It is backward compatible with previous versions including v2.1 + EDR and v3.0 + HS. For BR/EDR, it can support scatternet topology up to four active links in slave mode, and seven active links in master mode. For Low Energy, it supports multiple states and allows eight active links in master mode. Both BR/EDR and LE can operate simultaneously.

  The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.

• Co-location warning:
  This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter

• OEM integration instructions:

  • This device is intended only for OEM integrators under the following conditions:

  • The antenna must be installed such that 20 cm is maintained between the antenna and users, and the transmitter module may
    not be co-located with any other transmitter or antenna. The module shall be only used with the external antenna(s) that has
    been originally tested and certified with this module.

  • For all products market in US, OEM has to limit the operation channels in Channel 1 to Channel 11 or 3-9 as specified above
    by the supplied firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory
    Domain change.

  • As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still
    responsible for testing their end-product for any additional compliance requirements required with this module installed (for
    example, digital device emissions, PC peripheral requirements, etc.).
