MGA-684P8
Low Noise Active Bias Low Noise Amplifi er
Data Sheet
Description
Avago Technologies’ MGA-684P8 is an economical, easy-
to-use GaAs MMIC Low Noise Amplifi er (LNA). The LNA
has low noise and high linearity achieved through the
use of Avago Technologies’ proprietary 0.25 m GaAs
Enhancement-mode pHEMT process. It is housed in a
miniature 2.0 x 2.0 x 0.75 mm
(QFN) package. It is designed for optimum use from 1.5
GHz up to 4 GHz. The compact footprint and low profi le
coupled with low noise, high gain and high linearity make
the MGA-684P8 an ideal choice as a low noise amplifi er for
cellular infrastructure for GSM and CDMA. For optimum
performance at lower frequency from 450 MHz up to 1.5
GHz, MGA-683P8 is recommended. Both MGA-683P8 and
MGA-684P8 share the same package and pinout confi gu-
ration.
