Supports RF tests of the 6 GHz band, thus increasing the efficiency of wireless communication device production lines

Anritsu Corporation has launched the MU887002A-007 hardware option to extend the upper frequency of its TRX Test Module MU887002A for the Universal Wireless Test Set MT8870A/MT8872A from 6 GHz to 7.3 GHz.

With this hardware option, the MT8870A/MT8872A now supports RF tests of the 6 GHz band (5.925 to 7.125 GHz) used by the IEEE 802.11ax and NR-U standards, helping increase the efficiency of Wireless communication device production lines.

Development Background

Following U.S. FCC approval in April 2020 for unlicensed use of the 6 GHz band, countries worldwide are starting deployment tests. With its much wider 1200 MHz operation range coverage supporting higher communications speeds and larger data capacity, the 6 GHz band is expected to facilitate new applications and services. The IEEE 802.11ax WLAN standard regulates this 6 GHz band and the Wi-Fi Alliance is starting its Wi-Fi 6E certification program for IEEE 802.11ax 6 GHz devices.

Shipments of Wi-Fi 6E compliant wireless communication devices are starting in 2021 and are expected to reach a total of 800 million units in 2025.

Moreover, 3GPP Release 16 added NR-U to the unlicensed frequency bands for anticipated future use.

In these circumstances, production lines for wireless communication devices, such as smartphones and WLAN products, have an increasingly urgent demand for measuring instruments to evaluate 6 GHz band RF TRX performance.

To meet this demand, Anritsu has extended the upper frequency of the MU887002A module used by the Universal Wireless Test Set MT8870A/MT8872A to 7.3 GHz for evaluating 6 GHz band wireless communication device performance.

Product Outline

The Universal Wireless Test Set MT8870A and MT8872A are testers for mass-production of various types of communications equipment and modules. The TRX Test Modules MU887000A/01A/02A are installed in the main chassis and the mobile user equipment (UE) to be tested is connected to the TRX Test Module RF connectors to measure the Tx power, modulation accuracy, and Rx sensitivity required to evaluate the TRx performance. 

The TRX Test Module MU887002A with the built-in MU887002A-007 option can evaluate TRX performance in the 6 GHz band used by the IEEE802.11ax and NR-U standards.

Key Features

  • The MU887002A is compatible with the MU887000A/MU887001A and supports the 6 GHz band. It enables customers already using the MT8870A/MT8872A with these modules to support 6 GHz band measurements without major changes to the production-line setup.
  • The MU887002A supports a high modulated signal output power of –10 dBm (RMS) at frequencies of 6 GHz or more to enable RX tests, such as Max. Input Level measurement without an external amplifier.

Target Markets and Applications

  • Target Markets: Manufacturers of smartphones, modules, chipsets, and other WLAN communications equipment
  • Applications: Tuning Wireless communication device performance and evaluating TRX performance
