Description

Ultra low noise PHEMT packaged in a 1.4mm x 1.2mm x 0.7mm thin miniature leadless package. ATF-331M4's small size, high linearity and low noise figure is optimized for the design of hybrid module or first or second stage of basestation LNA.

The device ATF-331M4 is also suitable for applications in Wireless LAN, fixed wireless and other RF applications in the 450MHz to 10GHz frequency range.

Agilent Technologies's ATF-331M4 is a high linearity, low noise pHEMT housed in a miniature leadless package.

The ATF-331M4's small size and low profile makes it ideal f or the design of hybrid modules and other space-constraint devices.

Based on its featured performance, ATF-331M4 is ideal for the first or second stage of base station LNA due to the excellent combination of low noise figure and enhanced linearity[1]. The device is also suitable for applications in Wireless LAN, WLL/RLL, MMDS, and other systems requiring super low noise figure with good intercept in the 450 MHz to 10 GHz frequency range.
