ATF-551M4
Low Noise Enhancement Mode ÂPseudomorphic HEMT
in a ÂMiniature Leadless Package
Data Sheet
Description
Avago Technologiesâ ATF-551M4 is a high dynamic
range, super low noise, single supply EâpHEMT GaAs
FET housed in a thin miniature leadless package.
The combination of small device size, super low noise
(under 1â¯dB Fmin from 2 to 6â¯GHz), high linearity and
low power makes the ATF-551M4 ideal for LNA or hybrid
module designs in wireless receiver in the 450â¯MHz to
10â¯GHz frequency band.
Applications include Cellular/PCS/ WCDMA handsets
and data modem cards, fixed wireless infrastructure
in the 2.4, 3.5â¯GHz and UNII frequency bands, as well
as 2.4â¯GHz 802.11b, 5â¯GHz 802.11a and HIPERLAN/2
Wireless LAN PC-cards.
Note:
1. Avagoâs 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 450â¯MHz to 10 GHz frequency range.
