Qualcomm today said a number of leading handset makers have adopted its radio frequency front-end. Some of the OEMs include Google, HTC, LG, Samsung and Sony Mobile. This means these smartphone manufacturers will rely on Qualcomm's hardware to ensure their devices can talk to wireless networks. This is particularly important for T-Mobile, as the RF front end provides comprehensive 600 MHz band (B71) support. T-Mobile is deploying LTE on its 600 MHz spectrum now and plans to use it for 5G service down the road. The RF front end includes a modem-to-antenna system using the new QPM26xx series gallium arsenide-based power amplifier module. The module contains duplexers, envelope tracker, antenna tuners, antenna switches, and discrete and integrated filter modules. Qualcomm says its RF front end supports features such as Gigabit LTE, 4x4 MIMO and LTE Advanced today, and will evolve to handle 5G technologies in 2019.
