(QCN9074 2.4/5/6 GHz 4 x 4 11AX)

QCN9074-0 is an 802.11ax Wi-Fi 6E PCIe radio for Enterprise Access Points, Retail Routers, Range Extenders and Carrier Gateways.

QCN9074-0 with Qualcomm® 802.11ax technology is a highly integrated wireless local area network (WLAN) system-on-chip (SoC) for 2.4/5/6 GHz IEEE802.11ax/ac/n/g/b/a applications. QCN9074-0 performs AP and STA functionality with4x4 MIMO and 4 spatial streams. The QCN9074-0 is a dual-synthesizer WLAN radio with native 160 MHz support. It includes a CPU with local SRAM for time critical management functions of the media access layer (MAC) and physical layer (PHY). The QCN9074-0 integrates a multi- protocol MAC, 4x4 MIMO PHY, analog-to-digital/digital-to-analog converters (ADC/DAC), 4-antenna radio transceivers, and a PCIe interface in an all-CMOS device for low power consumption and small form-factor applications.

The QCN9074-0 chipset implements half-duplex OFDM, CCK, and DSSS PHY, and complies with IEEE 802.11a/b/g/n/ac/ax. In 5 GHz and 6 GHz bands, the maximum PHY rate of 4949 Mbps is achieved in 802.11ax 4x4/160 MHz native operation. In 2.4 GHz bands, a maximum PHY rate of 573.5 Mbps for 20 MHz and 1147 Mbps for 40 MHz is supported. Additional features include 

IEEE802.11ax and IEEE802.11ac explicit transmit beamforming (TxBF), DL/UL multi-user MIMO (MU-MIMO) up to 4 users, DL/UL multi user OFDMA up to 37 users, Dynamic Bandwidth Switching, agile DFS and agile spectrum analysis, where designated chain #3 scans another channel than the serving channel during listen receive intervals, Maximum Likelihood (ML) decoding, Low-Density Parity Check (LDPC), Maximum Ratio Combining (MRC), Space Time Block Code (STBC). The QCN9074-0 also supports the following protocols: IEEE802.11d/h/i/j/k/r/u/v/w/x.

The QCN9074-0 chipset supports up to four simultaneous spatial streams integrating four Tx and four Rx chains for high throughput and extended coverage. Tx chains combine PHY in-phase (I) and quadrature (Q) signals, convert them to the desired RF radio frequency. External power amplifiers (PAs) increase the signal strength to the desired EIRP. Rx chains receive from antennas through external LNAs. The frequency synthesizer supports 1-MHz steps to match frequencies defined by IEEE 802.11a/b/g/n/ac/ax specifications. The QCN9074-0 supports frame data transfer to and from the host using a 1 or 2 lane PCIe gen3 interface that supports interrupt generation and status reporting. Other external interfaces include EEPROM, GPIO, UART, PTA, and MCI interfaces for radio coexistence management.
