GaN MMIC front end module for phased array applications

04-03-2019 | Mouser Electronics | Subs & Systems

Qorvo QPF4001 GaN MMIC Front End Module, available from Mouser, is a multi-function device module targeted for 28GHz phased array 5G base stations and terminals. Fabricated on Qorvo’s 0.15um GaN on SiC process, the device 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 device 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 transmit path (PA + SW) offers 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 uses a low thermal resistance die attached process. This design makes the device ideal for phased array applications with tight lattice spacing and extreme temperature requirements.
