ATF-551M4
Low Noise Enhancement Mode Pseudomorphic
HEMT in a Miniature Leadless Package
Data Sheet
Description
The Broadcom® ATF-551M4 is a high dynamic range,
super low noise, single supply E-pHEMT GaAs FET
housed in a thin miniature leadless package.
The combination of small device size, super low noise
(under 1 dB Fmin from 2 to 6 GHz), high linearity and
low power makes the ATF-551M4 ideal for LNA or hybrid
module designs in wireless receiver in the 450 MHz to
10 GHz frequency band.
Applications include Cellular/PCS/ WCDMA handsets
and data modem cards, fixed wireless infrastructure
in the 2.4, 3.5 GHz and UNII frequency bands, as well
as 2.4 GHz 802.11b, 5 GHz 802.11a and HIPERLAN/2
Wireless LAN PC-cards.
Note:
1. Broadcom’s enhancement mode E-pHEMT devices are the first com-
mercially available single-supply GaAs transistors that do not need a
negative gate bias voltage for operation. They can help simplify the
design and reduce the cost of receivers and transmitters in many
applications in the 450 MHz to 10 GHz frequency range.
