The QPF4001 is a multi-function Gallium Nitride MMIC front - end module targeted for 28 GHz 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 QPF4001 operates from 26 GHz to 30 GHz. The receive path (LNA + TR SW) is designed to provide 17 dB of gain and a typical noise figure of 3.5dB. The transmit path (PA + SW) provides 27 dB of small signal gain with high linearity of 35 dBc ACPR and low EVM of 3% at 23 dBm average output power, while supporting peak power of 1 - Watt.

The compact 5 x 4 mm air-cavity laminate surface mount package with embedded copper heat slug employs a low thermal resistance die attached process, this makes QPF4001 ideal for phased array applications with tight lattice spacing and extreme temperature requirements.
