Qualcomm today introduced a new range of RF front-end products that will complement advanced processors such as the Snapdragon 835. The new family of radios are the first gallium arsenide (GaAs) power amplifier modules to come from Qualcomm. The company says the QPA546x and QPA436x are multimode, multiband power amplifier (MMPA) modules that are designed for superior cell-edge performance, which also makes them the first MMPA modules optimized for High Power User Equipment (HPUE) operation. Sprint plans to use HPUE later this year to improve the performance of its 2.5GHz spectrum to boost speed and capacity at the cell edge. The module family supports a range of other technologies, including Qualcomm TruSignal antenna performance. Qualcomm says its newest TruSignal design is better able to support carrier aggregation while also maximizing power efficiency over LTE. Consumers should see more consistent voice and data performance both indoors and out. The QAT35xx antenna is ready for the Snapdragon 835, while the QPA546x and QPA436x are sampling now with the expectation that they'll reach consumer devices later this year.
