QPF4005 37 40.5GHz GaN Dual Channel Front End Module Product Description The QPF4005 is a dual-channel multi-function Gallium Nitride MMIC front-end module targeted for 39GHz phased array 5G base stations and terminals. For each channel a multi-function MMIC die combines a low noise amplifier, a low insertion-loss high-isolation TR switch, and a high-gain high-efficiency multi-stage PA. The QPF4005 operates from 37 GHz to 40.5 GHz range. The receive path (LNA + T/R SW) is designed to provide 15dB of gain and a noise figure less than 4.5dB. The transmit path (PA + T/R SW) provides 18 dB of small signal gain and a saturated output power of 2W each channel. The compact 4.5 mm x 6.0 mm surface mount package configuration is designed to meet the tight lattice spacing requirements and support multi-channel/dual-polarization phased array applications. The QPF4005 is fabricated on Qorvos 0.15um GaN on SiC process. It is housed in an air-cavity laminate package Functional Block Diagram with an embedded copper heat slug. The copper slug, coupled with a low thermal resistance die-attach process, allows the QPF4005 to operate at the extreme case temperatures needed in phased array applications.
