In conjunction with NanoSemi Inc of Waltham, MA, USA, Qorvo Inc. says that it has demonstrated industry-leading ultra-wideband linearization results with its gallium nitride (GaN) power amplifiers for wireless infrastructure. Using the QPA2705 integrated GaN driver and GaN Doherty power amplifier with NanoSemi's proprietary digital compensation algorithms, the two firms have achieved adjacent channel power ratio (ACPR) of -58dBc for a 60MHz signal bandwidth and 3x20MHz LTE carrier configuration, and -55dBc for a 100MHz signal bandwidth and 5x20MHz LTE carrier configuration.
