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 perfor-
mance, 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 appli-
cations 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).
