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).
