QPF4001 GaN MMIC Front End Module

Qorvo QPF4001 GaN MMIC (Monolithic Microwave Integrated Circuit) Front End Module is a multi-function device module targeted for 28GHz phased array 5G base stations and terminals. Fabricated on Qorvo's 0.15um Gallium Nitride (GaN) on Silicon Carbide (SiC) process, the QPF4001 combines a low noise, high linearity LNA, a low insertion-loss high-isolation TR switch, and a high gain, high-efficiency multi-stage PA. The QPF4001 operates from 26GHz to 30GHz. The receive path (LNA + TR SW) is designed to provide 17dB of gain and a typical noise figure of 3.5dB. The Qorvo QPF4001 transmit path (PA + SW) provides 27dB of small signal gain with high linearity of 35dBc ACPR and low EVM of 3% at 23dBm average output power while supporting peak power of 1W. The compact 5mm x 4mm air-cavity laminate surface mount package with embedded copper heat slug employs a low thermal resistance die-attached process. The Qorvo QPF4001 GaN MMIC Front End Module design is ideal for phased array applications with tight lattice spacing and extreme temperature requirements.
