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).

Applications

• Tower mounted amplifier, low noise

amplifier and driver amplifier for

GSM/TDMA/CDMA base stations

• LNA for WLAN, WLL/RLL, MMDS

and wireless data infrastructures

• General purpose discrete PHEMT for

other ultra low noise applications
