ATF-331M4
Low Noise Pseudomorphic HEMT
in a Miniature Leadless Package
Data Sheet
Description
Avago 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).
