Accelerating 5G standards development is creating pressure for smartphone manufacturers to add 5G new radio (NR) support to handset designs. 5G introduces new challenging requirements and initial mobile deployments will create additional complex RF challenges. Innovative new RF solutions will be required to solve the complex challenges of 5G.
Qorvo reported revenue and earnings above guidance for fiscal Q2 of 2018, reflecting volume from mobile phone ramps at Apple and Chinese manufacturers and strong demand from the defense, Wi-Fi and IoT markets. During the quarter, the company took “targeted actions” that reduced headcount by some 300 people.
Qorvo published a free, downloadable calculator supporting a wide range of RF matching circuit tasks. MatchCalc™ provides ideal component values for matching S1P or S2P files to the desired system or reference impedance. MatchCalc offers capabilities not available in other downloadable tools and frees RF designers to work remotely.
Qorvo introduced a pre-matched, asymmetric Doherty amplifier covering 2.5 to 2.7 GHz that integrates two GaN on SiC transistors in a single NI-780 ceramic package. The QPD2731 Doherty delivers 50 W average output power with 60 percent efficiency.
Qorvo® is sampling what the company says is the industry’s first GaN on SiC front-end module (FEM) for the 39 GHz 5G band. The QPF4005 FEM integrates two identical, multi-function GaN MMICs into a footprint optimized for the phased array element spacing at 39 GHz. The FEM, which supports up to 256-QAM OFDM modulation, was designed for 5G base station architectures that use a phased array for beamforming.
