Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The QCA9880-BR4A-R s 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 low-level setup of WLAN physical layer (PHY) and RF to offload the host processor for other tasks. It enables high-performance 3x3 MIMO with three spatial streams for wireless applications demanding the highest robust link quality and maximum throughput and range. The QCA9880 integrates a multi-protocol MAC, PHY, analog-to-digital/digital-to-analog converters (ADC/DAC), 3x3 MIMO radio transceivers, and PCI Express interface in an all-CMOS device for low power consumption and small form-factor applications.

The QCA9880-BR4A-R implements half-duplex OFDM, CCK, and DSSS PHY, supporting 1.3 GBps for 802.11ac 80 MHz channel operation. It supports 802.11n up to 216.7 Mbps for 20 MHz and 450 Mbps for 40 MHz channel operations, and IEEE 802.11a/b/g data rates. Additional features include Maximal Likelihood (ML) decoding, Low-Density Parity Check (LDPC), Maximal Ratio Combining (MRC), Space Time Block Code (STBC), and On-Chip One-Time Programmable (OTP) memory to eliminate the need for an external flash and to further reduce the external component count and BOM cost. The QCA9880 supports 802.11 wireless MAC protocol, 802.11i security, Rx/Tx filtering, error recovery, and 802.11e quality of service (QoS).

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
