In the future, 5G network is developing towards network diversification, broadband, integration and intelligence. With the popularity of various intelligent terminals, mobile data traffic will grow explosively after 2020. In the future 5G technology, increasing the radio frequency working bandwidth of devices and improving the high-speed processing capacity are the core technologies to ensure the usage of future 5G network.
NR6816 Chip
Recently, Nufront launched a RF engine chip to meet the need of the future 5G terminal platform-NR6816. NR6816 adopts Zero IF architecture, integrates LNA and Pre-PA in the chip, receives and transmits IF filters, supports 3.2-3.8G frequency band. In addition, a single chip can support channel bandwidths with 20/40/80/100/160/200 MHz, and multi-channel can support the channel bandwidth up to 800MHz .

NR6816 supports quick mode switching, standby, receive, send, loop calibration, DPD and other working modes, and can optimize the power consumption of the chip in various modes. In addition, the chip supports fast gain switching, which can meet the application scenarios of AGC. NR6816's excellent reception and transmission performance can not only meet the system application of EUHT (Enhanced Ultra High Throughput), but also meet the requirements of 5G system in different scenarios such as user experience rate, flux density, time delay, energy efficiency and connection number, etc. Meanwhile, NR6816 also supports the performance requirement of 256QAM under 802.11ac160M, and the application of 1024QAM under 802.11ax.
