MWC: Qualcomm debuts modem-to-antenna tech

March 6th, 2018
At Mobile World Congress last week, Qualcomm Technologies, announced that the entire Qualcomm RF Front End (RFFE) modem-to-antenna solution and the Qualcomm Snapdragon 845 Mobile Platform with X20 Gigabit LTE, and 4K HDR video capture, are featured in Sony Mobile's Xperia XZ2 smartphone. 

Qualcomm Technologies is the first company in the semiconductor industry to deliver a comprehensive solution from modem to antenna ports for use in a leading premium smartphone. Utilizing Qualcomm Technologies’ comprehensive solution – including for the first time, the entire Qualcomm RFFE suite – allows Sony Mobile to benefit from system level optimization which facilitates the delivery of global platforms with superior connectivity performance and power efficiency.

The Qualcomm RFFE solution harnesses radio complexity and simplifies the implementation of global Gigabit LTE in mobile devices with a system-level design spanning a suite of RFFE products that utilize modem intelligence and are tightly integrated in a set of comprehensive global RF front end modules. It also helps OEMs to provide superior RF performance and power efficiency to support high data rates in real world networks.

Qualcomm Technologies’ modem-to-antenna solution comprises a suite of RFFE components including:

  • Power Amplifier Modules including Duplexers (PAMiDs). The QPM2621, QPM2632 and QPM2643 PAMiDs support the global low, mid and high bands respectively and integrate our suite of PAs, duplexers/filters including SAW, TC-SAW and BAW technologies, switches and an antenna coupler.
  • QET4100 Envelope Tracker (ET). The envelope tracker utilizes modem intelligence to dynamically adjust the voltage supplied to the radio frequency (RF) amplifier to support peak operating efficiency thereby reducing power consumption and heat.
  • Advanced Antenna Tuning. QAT3550 Impedance Tuner provide advanced adaptive antenna tuning. This technology utilizes modem intelligence to dynamically optimize the antenna match with the active transmit and receive frequencies to mitigate signal degradation from hand blocking, metal back designs and other effects, and is designed to improve throughput, call reliability and reduced power/battery consumption.
  • QDM3620, QDM3630, QDM3640 Diversity Receive Modules. These diversity receive modules combine our switches, BAW and SAW filters and low-noise amplifiers into a highly integrated module that is a user-friendly solution for implementing high-order MIMO and diversity receive paths for global LTE Advanced and Gigabit LTE architectures.

The QPM2621, QPM2632, QPM2643 PAMiDs, QAT3550 antenna impedance tuner, and QDM3620, QDM3630, QDM3640 diversity receive modules are supported for use with the Snapdragon X20 LTE modem and Snapdragon 845 Mobile Platform.

“With the proliferation of 4G frequencies and devices, coupled with 5G devices coming soon, OEMs and operators will be challenged to deliver high-quality user experiences while considering cost- and time-efficiency in developing mobile devices that work around the globe on a variety of networks,” said Christian Block, senior vice president and general manager, Qualcomm’s RF front end business unit. “Sony Mobile’s integration of Qualcomm Technologies’ RFFE modem-to-antenna solution showcases how Qualcomm Technologies works with customers to provide the tools they need to create new devices that can address the requirements and opportunities offered by Gigabit LTE and future 5G networks.”

With increasingly crowded networks, operators are challenged to bring maximum coverage and advanced features to users. Qualcomm RFFE modem-to-antenna solution is engineered to help operators maximize the use of all licensed, shared and unlicensed spectrum assets while delivering superior network coverage, device performance and worldwide roaming. With this solution, device OEMs can scale their products globally with support of hundreds of carrier aggregation and 4×4 MIMO combinations delivering connection speeds up to 1.2 Gigabit per second LTE.

“We are pleased to work closely with Qualcomm Technologies as we continue to introduce innovative smartphones,” said Izumi Kawanishi, director, executive vice president, product business group, Sony Mobile Communications Inc. “Qualcomm Technologies’ enables excellent RF Front End performance across low, mid and high bands, and its comprehensive tightly integrated modem-RFFE interaction, provides the system level optimization we need to deliver the best-in-class mobile experience our customers expect.”

As the radio environment becomes more complex, a well-designed, advanced RFFE system is critical to the mobile experiences end-users demand from their devices and to prepare for the launch of 5G devices. Qualcomm Technologies’ comprehensive modem-to-antenna solutions are optimized to support exceptional connection reliability, blazing-fast data speeds, superior indoor/outdoor coverage, world roaming capability and long battery life.
