Introducing the 16 nm Transceiver Family for The 6 GHz Band Radio Solution

The recent allocation of the 6 GHz band for wireless communication systems has opened up new possibilities for high-speed and low-latency applications. Analog Devices’ 16 nm transceiver family offers a highly integrated solution for this new frequency band, featuring low power consumption and high performance. This article introduces the 6 GHz band and discusses the benefits of the zero-IF architecture employed in ADI’s transceiver family. This article also highlights the key features of this transceiver family and explores their application in various scenarios.

With the forward momentum of wireless communication systems, new technologies and new spectrum are continuously being pursued and adopted. For those involved in the wireless industry, it’s no surprise that the 3GPP’s inclusion of the 6 GHz frequency band in frequency range 1 (FR1) was welcome news. By expanding the original FR1 from 450 MHz to 6000 MHz to 410 MHz to 7125 MHz, the industry gains access to a significant amount of new spectrum, opening up fresh opportunities for growth and innovation.

Compared to the legacy FR1 frequency band, the new 6 GHz band supports much wider bandwidths, with n96 at 1200 MHz, n102 at 500 MHz, and n104 at 700 MHz. Offering high-capacity spectrum with good network energy performance and better propagation than frequency range 2 (FR2) bands ensures that the new 6 GHz band will become an important resource for wireless connectivity. In the U.S., the Federal Communication Commission (FCC) earmarked the band for unlicensed Wi-Fi in 2020, making the 6 GHz band highly competitive in this market.

This article reviews the features and benefits of ADI’s 16 nm transceiver family for these applications. Available in both 8T8R and 4T4R configurations, the ADI 16 nm transceiver is a highly integrated device with extensive digital front-end functionality, including DPD, CFR, and CDDC/CDUC. It also includes energy-saving features.

The ADI 16 nm transceiver series integrates differential transmitters and receivers and observation receivers. The tunable frequency ranges from 400 MHz to 7125 MHz, and the tunable bandwidth is as wide as 600 MHz. With a high-speed JESD204B/JESD204C interface, it can connect to the baseband processor.

The transmitter in the transceiver applies zero-IF architecture, providing higher linearity and noise performance with relatively lower power consumption than RF sampling converters. The receiver path uses an analog demodulator and a continuous-time delta-sigma ADC to downconvert RF input to a baseband I/Q signal. The ADC incorporates inherent antialiasing filtering, significantly relaxing filtering requirements.

In conclusion, ADI’s 16 nm transceiver family offers a powerful and flexible solution for various wireless communication applications in the 6 GHz band. With its zero-IF architecture, high integration, and low power consumption, it is well-suited for wireless Massive MIMO systems, Wi-Fi systems, and other applications requiring high performance and energy efficiency.
