MGA-631P8-BLKG

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18
MGA-631P8
Low Noise, High Linearity, Active Bias Low Noise Amplier
Data Sheet
Description
Avago Technologies’ MGA-631P8 is an economical, easy-
to-use GaAs MMIC Low Noise Amplier (LNA) with active
bias. The LNA has low noise with excellent input return
loss and high linearity achieved through the use of
Avago Technologies’ proprietary 0.5um GaAs Enhance-
ment-mode pHEMT process. The LNA has an extra feature
that allows a designer to adjust supply current and gain
externally. Due to the high isolation between the input
and output, gain can be adjusted independently through
a resistor in series with a blocking capacitor from the
output pin to FB1 pin, without aecting the noise gure.
It is housed in a miniature 2.0 x 2.0 x 0.75mm
3
8-pin Thin
Small Leadless Package (TSLP) package. The compact
footprint and low prole coupled with low noise, high
gain, excellent input return loss and high linearity make
the MGA-631P8 an ideal choice as an LNA for cellular in-
frastructure for GSM, CDMA, GPS and ISM applications.
It is designed for optimum use between 400MHz to
1.5GHz. For optimum performance at higher frequency
from 1.4GHz to 3.8GHz, the MGA-632P8 is recommend-
ed. Both MGA-631P8 and MGA-632P8 share the same
package and pinout.

eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
