MGA-683P8

Low Noise And High Linearity Active Bias

Low Noise Amplifi er

Data Sheet

Description

Avago Technologies’ MGA-683P8 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 450

MHz up to 2 GHz. The compact footprint and low profi le

coupled with low noise, high gain and high linearity make

the MGA-683P8 an ideal choice as a low noise amplifi er for

cellular infrastructure for GSM and CDMA. For optimum

performance at higher frequency from 1.5 GHz to 4 GHz,

the MGA-684P8 is recommended. Both MGA-683P8 and

MGA-684P8 share the same package and pinout.
