ATF-541M4
Low Noise Enhancement Mode ­Pseudomorphic HEMT
in a ­Miniature Leadless Package
Data Sheet
Description
Avago Technologies’ ­ ATF­‑541M4 is a high linearity, low
noise, single supply E‑PHEMT housed in a miniature lead‑
less package.
The ATF-541M4’s small size and low profile makes it ideal
for the design of hybrid module and other space-con‑
straint devices.
The device can be used in applications such as TMA and
front end LNA for Cellular/PCS and WCDMA base stations,
LNA and driver amplifiers for Wireless Data and 802.11b
WLAN.
In addition, the device’s superior RF performance at higher
frequency makes it an ideal candidate for high frequency
applications such as WLL, 802.11a WLAN, 5–6 GHz UNII
and HIPERLAN applications.

Applications
• Low Noise Amplifier and Driver Amplifier for Cellular/
PCS and WCDMA Base Stations
• LNA and Driver Amplifier for WLAN, WLL/RLL and
MMDS applications
• General purpose discrete E-PHEMT for ultra low noise
applications in the 450 MHz to 10 GHz frequency range
Note:
1. Enhancement mode technology requires positive Vgs, thereby
eliminating the need for the negative gate voltage associated with
conventional depletion mode devices.
