Agilent ATF-331M4 Low Noise Pseudomorphic HEMT in a Miniature Leadless Package
Data Sheet
Description 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 for 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.
Note: 1. From the same PHEMT FET family, the
smaller geometry ATF-34143 may also be considered for the higher gain performance, particularly in the higher frequency band (1.8 GHz and up).
