Qualcomm unveils 5G NR millimeter wave (mmWave) and sub-6 GHz RF modules for phones

Qualcomm today unveiled the Qualcomm QTM052 mmWave antenna module family, alongside the Qualcomm QPM56xx sub-6 GHz RF module family. They pair with the Qualcomm Snapdragon X50 5G modem in order to bring modem-to-antenna capabilities to smartphones.

The new batch of radio frequency (RF) solutions refer to both mmWave and sub-6GHz, and are designed for smartphones and other mobile devices. when paring these latest RF modules with the Snapdragon X50 modem, Qualcomm believes they are able to offer OEMs an incredibly compact end-to-end 5G solution. The solutions will be able to offer 5G coverage in dense urban areas and broad 5G NR coverage.

Today’s announcement of the first commercial 5G NR mmWave antenna modules and sub-6 GHz RF modules for smartphones and other mobile devices represents a major milestone for the mobile industry. Qualcomm Technologies’ early investment in 5G has allowed us to deliver to the industry a working mobile mmWave solution that was previously thought unattainable, as well as a fully-integrated sub-6 GHz RF solution. Now, these type of modem-to-antenna solutions, spanning both mmWave and sub-6 spectrum bands, make mobile 5G networks and devices, especially smartphones, ready for large scale commercialization. With 5G, consumers can expect gigabit-class Internet speeds with unprecedented responsiveness in the palm of their hands, which stand to revolutionize the mobile experience“,  said Cristiano Amon, President, Qualcomm Incorporated.

Millimeter wave (mmWave) signals have been a real headache for smartphone manufacturers. They pose problems from almost all perspectives, from materials used to form-factor, industrial design, thermals, and regulatory requirements for radiated power. Hence, mmWave was considered “highly impractical” for mobile devices.

With Qualcomm’s QTM052 mmWave antenna modules that work in tandem with the Snapdragon X50 5G modem, many of the challenges are solved. They offer beam-forming support, beam steering, and beam tracking technologies, which improve mmWave signal power and range. They feature an integrated 5G NR radio transceiver power management IC, RF front-end components and phased antenna array, that support 800 MHz of bandwidth in the 26.5-29.5 GHz (n257), as well as the entire 27.5-28.35 GHz (n261) and 37-40 GHz (n260) mmWave bands.

Both the QTM052 mmWave antenna module family and the QPM56xx sub-6 GHz RF module family are available to Qualcomm’s customers already. When exactly we will see them in our future devices is yet unknown, but with 5G getting closer and closer, we’re guessing pretty soon. 

 Qualcomm Delivers Breakthrough 5G NR mmWave and Sub-6 GHz RF Modules for Mobile Devices 

New family of mmWave antenna modules makes mobile mmWave viable in a smartphone form factor, supporting large-scale commercialization — 

SAN DIEGO — July 23, 2018 — Qualcomm Technologies, Inc., a subsidiary of Qualcomm Incorporated (NASDAQ: QCOM), today unveiled the world’s first fully-integrated 5G NR millimeter wave (mmWave) and sub-6 GHz RF modules for smartphones and other mobile devices. The Qualcomm® QTM052 mmWave antenna module family and the Qualcomm® QPM56xx sub-6 GHz RF module family pair with the Qualcomm® Snapdragon™ X50 5G modem to deliver modem-to-antenna capabilities across several spectrum bands, in a very compact footprint that is suited for integration in mobile devices. 

“Today’s announcement of the first commercial 5G NR mmWave antenna modules and sub-6 GHz RF modules for smartphones and other mobile devices represents a major milestone for the mobile industry. Qualcomm Technologies’ early investment in 5G has allowed us to deliver to the industry a working mobile mmWave solution that was previously thought unattainable, as well as a fully-integrated sub-6 GHz RF solution. Now, these type of modem-to-antenna solutions, spanning both mmWave and sub-6 spectrum bands, make mobile 5G networks and devices, especially smartphones, ready for large scale commercialization,” said Cristiano Amon, President, Qualcomm Incorporated. “With 5G, consumers can 

expect gigabit-class Internet speeds with unprecedented responsiveness in the palm of their hands, which stand to revolutionize the mobile experience.” 

To date, mmWave signals have not been used for mobile wireless communications due to the many technical and design challenges they pose, which impact nearly every aspect of device engineering, including materials, form-factor, industrial design, thermals, and regulatory requirements for radiated power. As such, many in the mobile industry considered mmWave highly impractical for mobile devices and networks, and thus unlikely to materialize. 

The QTM052 mmWave antenna modules work in tandem with the Snapdragon X50 5G modem, as a comprehensive system, to help overcome the formidable challenges associated with mmWave. They support advanced beam forming, beam steering, and beam tracking technologies, drastically improving the range and reliability of mmWave signals. They feature an integrated 5G NR radio transceiver, power management IC, RF front-end components and phased antenna array. They support up to 800 MHz of bandwidth in the 26.5-29.5 GHz (n257), as well as the entire 27.5-28.35 GHz (n261) and 37-40 GHz (n260) mmWave bands. Most importantly, the QTM052 modules integrate all these capabilities in a very compact footprint, such that up to four of them can be integrated in a smartphone. This allows OEMs to continue evolving the industrial design of their mobile devices, offering attractive form factors combined with the benefits of extremely high speeds from mmWave 5G NR, and making such devices available for launch as early as 2019. 

While mmWave is best suited for providing 5G coverage in dense urban areas and crowded indoor environments, broad 5G NR coverage will be achieved in sub-6 GHz spectrum bands. As such, the QPM56xx RF module family (including the QPM5650, QPM5651, QDM5650, and QDM5652) is designed to allow smartphones based on the Snapdragon X50 5G modem to support 5G NR in sub-6 GHz 

RF bands. The QPM5650 and QPM5651 feature integrated 5G NR PA/LNA/Switch and filtering subsystem. The QDM5650 and QDM5652 feature integrated 5G NR LNA/switch and filtering subsystem for diversity and MIMO support. All four modules offer integrated SRS switching required for optimum massive MIMO applications and support for 3.3-4.2 GHz (n77), 3.3-3.8 GHz (n78) and 4.4-5.0 GHz (n79) sub-6 bands. These sub-6 GHz RF modules provide mobile device makers with a viable path to delivering on the promise of 5G NR massive MIMO technology in mobile devices. 

Both the QTM052 mmWave antenna module family and the QPM56xx sub-6 GHz RF module family are now sampling to customers.
