MGA-634P8

Ultra Low Noise, High Linearity Low Noise Amplifi er

Data Sheet

Description

Avago Technologies’ MGA-634P8 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 0.25um GaAs Enhance-

ment-mode pHEMT process. It is housed in a miniature 2.0

x 2.0 x 0.75mm

It is designed for optimum use from 1.5 GHz up to 2.3 GHz.

The compact footprint and low profi le coupled with low

noise, high gain and high linearity make the MGA-634P8

an ideal choice as a low noise amplifi er for cellular infra-

structure for GSM and CDMA. For optimum performance at

lower frequency from 450MHz up to 1.5GHz, MGA-633P8

is recommended. For optimum performance at higher

frequency from 2.3GHz up to 4GHz, MGA-635P8 is recom-

mended. All these 3 products, MGA-633P8, MGA-643P8

and MGA-653P8 share the same package and pinout con-

fi guration.
