MGA-635P8

Ultra Low Noise, High Linearity Low Noise Amplifier

Data Sheet

Description

Avago Technologies’ MGA-635P8 is an economical, easy-

to-use GaAs MMIC Low Noise Amplifier (LNA). The LNA has

low noise and high linearity achieved through the use of

Avago Technologies’ proprietary 0.25Pm 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 2.3GHz up to 4GHz.

The compact footprint and low profile coupled with low

noise, high gain and high linearity make the MGA-635P8

an ideal choice as a low noise amplifier for cellular infra-

structure for LTE, GSM and CDMA. For optimum perfor-

mance at lower frequency from 450MHz up to 1.5GHz,

MGA-633P8 is recommended. For optimum performance

at frequency from 1.5GHz up to 2.3GHz, MGA-634P8

is recommended. All these 3 products, MGA-633P8,

MGA-643P8 and MGA-653P8 share the same package and

pinout configuration.
