MGA-645T6
Low Noise Amplifier with Bypass/Shutdown Mode
in Low Profile Package
Data Sheet
Description
Avago Technologies’ MGA-645T6 is an economical,
easy-to-use GaAs MMIC Low Noise Amplifier (LNA) with
Bypass/ Shutdown mode. The LNA has low noise and
high linearity achieved through the use of Avago Tech-
nologies’ 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
profile 2 x 1.3 x 0.4mm 6-pin Ultra Thin Package. The
compact footprint and low profile coupled with low
noise, high linearity make the MGA-645T6 an ideal choice
as a low noise amplifier for mobile receiver in the WiMax,
WLAN(802.11b/g), WiBro and DMB applications.
