Qualcomm recently announced the world's first fully integrated 5G new air interface (5G NR) millimeter wave and below 6GHz RF module for smartphones and other mobile devices.
Qualcomm's QTM052 millimeter wave antenna module series and Qualcomm's QPM56xx 6 GHz RF module series can be combined with Qualcomm Snapdragon X50 5G modem to provide multiple functions from modem to antenna and across frequency bands, and support compact package size for mobile Terminal integration.
Qualcomm President Christiano Amon said: "Today's release of the first commercial 5G new air interface millimeter wave antenna module for smartphones and other mobile devices and RF modules below 6 GHz is an important milestone for the mobile industry. Forward-looking investments in the 5G space allow us to offer the industry a mobile millimeter-wave solution that was once considered unachievable, as well as a fully integrated RF solution below 6 GHz. Currently, this type of modem from RF to RF and across the millimeter wave and below 6 GHz The solution is enabling mobile 5G networks and terminals, especially smartphones, to be ready to support large-scale commercial use. With the advent of 5G, consumers can expect to enjoy gigabit network speeds and unprecedented levels in their hands. The responsiveness of these will continue to revolutionize the mobile experience."
Millimeter-wave signals have not been used in mobile wireless communications to date due to numerous technical and design challenges. These challenges cover almost every aspect of end-of-line engineering, including materials, form factor, industrial design, thermal and radiant power regulatory requirements. In view of this, many people in the mobile industry believe that the application of millimeter waves in mobile terminals and networks is impractical and unrealizable.
The Qualcomm QTM052 millimeter wave antenna module works in tandem with the Snapdragon X50 5G modem to form a complete system to meet the enormous challenges of millimeter waves. As a complete system, it supports advanced beamforming, beam steering and beam tracking techniques to significantly improve the coverage and reliability of millimeter-wave signals. The system includes an integrated 5G new air interface radio transceiver, power management IC, RF front-end components and phased antenna array, and is available at 26.5-29.5 GHz (n257) and full 27.5-28.35 GHz (n261) and 37-40 GHz ( Supports up to 800MHz bandwidth on the n260) millimeter wave band. Most importantly, the QTM052 module integrates all of these features into a compact package size that supports up to four QTM052 modules in a single smartphone. This will enable OEMs to continually optimize the industrial design of their mobile terminals and help them develop mobile terminals that are aesthetically pleasing and have ultra-high-speed millimeter-wave 5G air-to-air, and support these terminals to be launched in the first half of 2019.
Millimeter waves are suitable for providing 5G coverage in dense urban areas and crowded indoor environments, while extensive coverage of 5G new airspace will be achieved through the frequency band below 6 GHz. In view of this, the QPM56xx RF module series (including QPM5650, QPM5651, QDM5650 and QDM5652) can help smartphones equipped with Opteron X50 5G modems to support 5G new air ports in the frequency band below 6GHz. The QPM5650 and QPM5651 include an integrated 5G new air interface power amplifier (PA) / low noise amplifier (LNA) / switch and filtering subsystem. The QDM5650 and QDM5652 include an integrated 5G new air interface low noise amplifier/switch and filtering subsystem to support diversity and MIMO technology. All four modules support integrated channel sounding reference signal (SRS) switching to provide optimal massive MIMO applications and support 3.3-4.2 GHz (n77), 3.3-3.8 GHz (n78) and 4.4-5.0 GHz ( N79) Band below 6 GHz. These RF modules below 6 GHz provide mobile terminal manufacturers with a feasible path to support 5G new air interface massive MIMO technology in mobile terminals.
At present, the QTM052 millimeter wave antenna module series and the QPM56xx 6GHz or lower RF module series are being sampled to customers.
