Qualcomm has announced that the entire Qualcomm  RF Front End (RFFE) modem-to-antenna solution along with the Snapdragon 845 Mobile Platform are under the bonnet of Sony Mobile’s new Xperia XZ2 smartphone.

Qualcomm said it was the first to deliver a comprehensive solution from the modem to antenna ports for use in a leading premium smartphone.

The Qualcomm RFFE simplifies the implementation of global Gigabit LTE in mobile devices with a system-level design spanning a suite of RFFE products that use modem intelligence and are integrated into a set of comprehensive global RF front-end modules.

The big idea is that OEMs can spruce up 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) an envelope tracker uses 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 provides advanced adaptive antenna tuning. This technology uses modem intelligence to dynamically optimise 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. This diversity receives modules combine our switches, BAW and SAW filters and low-noise amplifiers into a highly integrated module that brings high-order MIMO and diversity receive paths for global LTE Advanced and Gigabit LTE architectures. 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.

Qualcomm’s RF front-end business unit senior vice president and general manager Christian Block said that 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.

 “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.”

Qualcomm RFFE modem-to-antenna solution is engineered to help operators maximise 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 the support of hundreds of carrier aggregation and 4x4 MIMO combinations delivering connection speeds up to 1.2 Gigabit per second LTE, he said.

Izumi Kawanishi, director, executive vice president, product business group, Sony Mobile Communications said:   "Qualcomm  enables excellent RF Front-End performance across low, mid and high bands, and its comprehensive tightly integrated modem-RFFE interaction, provides the system level optimisation we need to deliver the best-in-class mobile experience our customers expect.”
