MGA-645T6
Low Noise Ampliï¬er with Bypass/Shutdown Mode
in Low Proï¬le Package
Data Sheet
Description
Avago Technologiesâ MGA-645T6 is an economical,
easy-to-use GaAs MMIC Low Noise Ampliï¬er (LNA) with
Bypass/ Shutdown mode. The LNA has low noise and
high linearity achieved through the use of Avago Tech-
nologiesâ proprietary 0.5um GaAs Enhancement-mode
pHEMT process. The Bypass/Shutdown mode enables
the LNA to be bypassed during high input signal power
and reduce current consumption. It is housed in a low
proï¬le 2 x 1.3 x 0.4mm 6-pin Ultra Thin Package. The
compact footprint and low proï¬le coupled with low
noise, high linearity make the MGA-645T6 an ideal choice
as a low noise ampliï¬er for mobile receiver in the WiMax,
WLAN(802.11b/g), WiBro and DMB applications.
