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).

Notes:
1. Measurements made on fixed tuned
production test board that was tuned for
optimal gain match with reasonable noise
figure at 4V 60 mA bias. This circuit
represents a trade-off between an optimal
noise match, maximum gain match and a
realizable match based on production test
board requirements. Circuit losses have been
de-embedded from actual measurements.
2. Quiescent drain current, Idsq, is set with zero
RF drive applied. As P1dB is approached, the
drain current may increase or decrease
depending on frequency and dc bias point. At
lower values of Idsq the device is running
closer to class B as power output approaches
P1dB. This results in higher P1dB and higher
PAE (power added efficiency) when compared
to a device that is driven by a constant
current source as is typically done with active
biasing.
