New Qualcomm modules allow you to make thin 5G-smartphones


Qualcomm Technologies has introduced advanced modules for the operation of mobile devices in fifth-generation networks. Specifically, specifically for the Snapdragon X50 5G modem, the manufacturer has developed the first fully integrated commercial modules for the 5G NR mmWave millimeter range and radio modules supporting frequencies up to 6 GHz. This opens the possibility of creating smartphones and other mobile devices using new technologies, but without increasing their size.

“Our announcement of the first commercial 5G NR mmWave antenna modules and radio modules supporting frequencies up to 6 GHz for smartphones and other mobile devices is an important milestone for the entire mobile communications industry. Investments of Qualcomm Technologies in 5G allowed us to present a working solution for millimeter-wave communication in the form factor of mobile devices, previously considered unrealizable, as well as a fully integrated solution supporting frequencies up to 6 GHz. Now, new solutions such as “modem-antenna” will allow commercialization of mobile networks and 5G devices to a whole new level. With 5G, consumers will gain access to the Internet at gigabit speeds with a minimum delay from gadgets that fit easily on the palm of your hand. This will be a real revolution in the user experience in mobile devices, “said Cristiano Amon, president of Qualcomm Incorporated.

Earlier, signals in the millimeter range were not used in mobile wireless communications due to the large number of technical and design complications associated with materials, form factor, design, cooling and regulatory requirements for radiation levels. New Qualcomm modules solve all the problems.

Modules QTM052 mmWave work in tandem with 5G-modem Snapdragon X50 as a single system, allowing to solve problems of using mobile devices in the millimeter range. Modules support advanced technologies for beam formation, control and tracking, which significantly increase the range and stability of signals in the millimeter range. Novelties are equipped with built-in transceiver 5G NR, integrated power management scheme, radio components of input stages and phased array antenna. They support operation on the band up to 800 MHz in the frequency bands 26.5-29.5 GHz (n257), 27.5-28.35 GHz (n261) and 37-40 GHz (n260). In addition, the QTM052 mmWave has a compact size, which allows the use of up to four such modules in one smartphone. As a result, OEMs will be able to make their gadgets compact and with access to high speeds of 5G NR mmWave. The launch of the first mobile devices with new modules is possible already in 2019.

The millimeter range is best suited for providing coverage of 5G in densely populated and densely built urban areas and in rooms with large concentrations of people and technology, but a wider coverage of the 5G NR will be obtained using a frequency range of up to 6 GHz. Therefore, the QPM56xx radio module (including the QPM5650, QPM5651, QDM5650 and QDM5652 models) is designed to provide 5G NR communication in smartphones based on the Snapdragon X50 5G modem in this range. All four modules also support the integrated SRS switching required to optimize the use of Massive MIMO technology, and operate in the frequency bands 3.4-4.2 GHz (n77), 3.3-3.8 GHz (n78) and 4.4 -5.0 GHz (n79). New radio modules allow mobile device developers to implement Massive MIMO 5G NR technology support. Antenna module QTM052 mmWave and radio modules QPM56xx are at the stage of sending to partners.
