The QPF4001 is a GaN front-end module (FEM) for 28 GHz phased array 5G base stations and terminals. It integrates a high linearity LNA, a low loss transmit/receive switch and a high-gain, high-efficiency multi-stage PA in a single MMIC. The FEM operates from 26 GHz to 30 GHz. The receive path (LNA + TR SW) is designed to provide a gain of 17 dB and a noise figure of 3.5 dB. The transmit path (PA + SW) provides a small signal gain of 27 dB with high linearity of 35 dBc ACPR and low EVM of 3% at 23 dBm average output power, while supporting a peak power of 1 Watt. It is available in a 5 x 4 mm air-cavity laminate surface mount package with embedded copper heat slug making it ideal for phased array applications with tight lattice spacing and extreme temperature requirements.
