Shenzhen Mingjiada Electronics Co., Ltd. sells (Qualcomm) System-on-Chip QCA9880-BR4A-R Dual-Band 3x3 MIMO 802.11ac/abgn WLAN SoCs

QCA9880-BR4A-R Device Overview:

The QCA9880 is a highly integrated wireless local area network (WLAN) system-on-chip (SoC) for 5 GHz 802.11ac or 2.4/5 GHz 802.11n WLAN applications.The QCA9880 integrates an on-board CPU for underlying WLAN physical layer (PHY) and RF setup to offload the main processor for other tasks. It enables high-performance 3x3 MIMO with three spatial streams for wireless applications requiring the highest robust link quality, maximum throughput, and maximum range. the QCA9880 integrates a multi-protocol MAC, PHY, analog-to-digital/digital-to-analog converter (ADC/DAC), 3x3 MIMO radio transceiver, and PCI Express interfaces in a full CMOS device for low-power and small form factor applications. low power and small form factor applications.

The QCA9880 implements half-duplex OFDM, CCK, and DSSS PHY and supports 802.11ac 80 MHz channel operation at 1.3 GBps. It supports 802.11n 20 MHz up to 216.7 Mbps and 40 MHz up to 450 Mbps channel operation, as well as IEEE 802.11a/b/g data rates. Other features include maximum likelihood (ML) decoding, low-density parity check (LDPC), maximum ratio combining (MRC), space-time block coding (STBC), and on-chip one-time programmable (OTP) memory, eliminating the need for external flash and further reducing the number of external components and BOM cost. The QCA9880 supports 802.11 wireless MAC protocols, 802.11 i security, Rx/Tx filtering, error recovery, and 802.11e quality of service (QoS).
