Qualcomm's 2nd gen 5G modem targets 7 Gbps peak downlink

Qualcomm has begun sampling its 2nd generation 5G New Radio (NR) modem chip --  a 7-nanometer device that supports 5G NR mmWave and sub-6 GHz spectrum bands with up to 7 Gbps download speeds and 3 Gbps upload speeds over 5G, and Category 22 LTE with up to 2.5 Gbps LTE download speeds.

The Snapdragon X55 5G modem is designed for global 5G rollouts and is expected to hit the market in commercial devices by late 2019. Target applications include premium smartphones, mobile hotspots, Always Connected PCs, laptops, tablets, fixed wireless access points, extended reality devices, and automotive applications.


Qualcomm highlights support for all major frequency bands, whether mmWave or sub-6 GHz, supports TDD and FDD modes of operations and is capable of both Standalone (SA) and non-standalone (NSA) network deployments – providing flexibility and enabling virtually all deployment types globally. The modem is also engineered to support dynamic spectrum sharing between 4G and 5G, enabling operators to accelerate 5G deployments by using their existing 4G spectrum holdings to deliver both 4G & 5G services dynamically. It supports 100 MHz envelope tracking technology, and adaptive antenna tuning for 5G sub-6 GHz, designed for power-efficient connectivity.


“Qualcomm Technologies is spearheading the first wave of 5G launches with our first generation 5G mobile platform. With significant evolution in capabilities and performance, our second generation commercial 5G modem is a true testament to the maturity and leadership of our 5G technology. We expect our 5G platform to accelerate 5G commercial momentum and power virtually all 5G launches in 2019 while significantly expanding the global 5G rollout footprint,” said Cristiano Amon, president, Qualcomm Incorporated.

The Snapdragon X55 5G modem pairs with the newly announced 5G mmWave antenna module (QTM525), a new single-chip 14nm RF transceiver for 5G sub-6 GHz and LTE, and sub-6 GHz RF front-end modules to deliver the next generation modem-to-antenna solution for all major spectrum bands. The new QTM525 5G mmWave antenna module builds on the innovation of Qualcomm Technologies’ first mmWave antenna module by reducing the height of the module to support 5G smartphone designs sleeker than 8 millimeters thick. The new module adds support for band n258 (24.25 – 27.5 GHz) for North America, Europe and Australia on top of bands n257 (26.5 – 29.5 GHz), n260 (37 – 40 GHz) and n261 (27.5 – 28.35 GHz) already supported by its predecessors. Qualcomm is also launching the world’s first announced 5G 100MHz envelope tracking solution, QET6100, as well as a family of integrated 5G/4G power amplifier (PA) and diversity modules, and the QAT3555 5G adaptive antenna tuning solution.

“OEMs face a range of formidable design challenges when it comes to 5G. The need to support multimode operation from 5G to 2G, along with an ever-increasing number of band combinations, brings unprecedented complexity,” added Amon. “Discrete modem or RF solutions are no longer sufficient. Qualcomm Technologies is unique in the mobile industry by offering a comprehensive modem-to-antenna solution, and we are pioneering efforts in all aspects of 5G and ready to enable our customers with these capabilities to help them commercialize the first wave of 5G devices this year.”
