MGA-655T6
Low Noise Amplifier with Bypass Mode
in Low Profile Package
Data Sheet
Description
Avago Technologies’ MGA-655T6 is an economical,
easy-to-use GaAs MMIC Low Noise Amplifier (LNA) with
Bypass mode. The LNA has low noise and high linear-
ity achieved through the use of Avago Technologies’
proprietary 0.5 µm GaAs Enhancement-mode pHEMT
process. The Bypass mode enables the LNA to be by-
passed during high input signal power and reduce
current consumption. It is housed in a low profile 2 x 1.3
x 0.4 mm 6-pin Ultra Thin Package. The compact foot-
print and low profile coupled with low noise, high linear-
ity make the MGA-655T6 an ideal choice as a low noise
amplifier for mobile and CPE receivers in the WiMax and
WLL (2.5-4) GHz band.
