In the last year, the increasing develop-ment of 5G has reshaped the Radio Frequency (RF) power industry landscape, driving the RF GaN market. Compared to existing silicon LDMOS and GaAs solutions, GaN devices are able to deliver the power/efficiency level required for next-generation high frequency telecom networks. The Low Noise Amplifier (LNA) market is expected to deliver a 16% Compound Annual Growth Rate (CAGR) with the implementation of diversity modules, along with integration in Power Amplifier (PA) modules for handsets.


Qorvo was the first player to unveil a Front-End Module (FEM) for ultra-high band coverage based on GaN-on-SiC 0.15µm technology.


System Plus Consulting unveils Qorvo’s design, presenting our reverse costing of the QPF4006 39GHz GaN Monolithic Microwave Integrated Circuit (MMIC) FEM. The device is targeted for 5G base stations and terminals and combines, on the same die, a high linearity LNA, a low insertion-loss Transmit Receive (TR) switch and a high gain PA.


The QPF4006 is assembled in an air-cavity laminate package with embedded copper heat slug which demonstrates Qorvo’s internal test and packaging capability.


The device is manufactured with 0.15µm gate technology and AlGaN/GaN epitaxial structure deposited on a SiC substrate. Other than MMIC components it includes TaN resistors, SiN capacitors and three levels of metal interconnects including gold airbridges.


This report includes a detailed analysis of the packaging and the GaN on SiC transistor with optical and Scanning Electron Microscope (SEM) pictures. Moreover it provides a cost analysis for the complete device.
