MGA-631P8
Low Noise, High Linearity, Active Bias Low Noise Amplifier
Data Sheet
Description
Avago Technologies’ MGA-631P8 is an economical, easy-
to-use GaAs MMIC Low Noise Amplifier (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 Enhancement-
mode pHEMT process. The LNA has an extra feature that
allows a designer to adjust supply current and gain ex-
ternally. 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 affecting the noise figure.
It is housed in a miniature 2.0 x 2.0 x 0.75mm3 8-pin Thin
Small Leadless Package (TSLP) package. The compact
footprint and low profile 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 3GHz, the MGA-632P8 is recommend-
ed. Both MGA-631P8 and MGA-632P8 share the same
package and pinout.

Specifications
900MHz; 4V, 60mA (typ)
17.5 dB Gain
0.53 dB Noise Figure
-19.4dB S11
-34dB S12
33.1 dBm Output IP3

CDMA, GPS and ISM.
Other ultra low noise applications.
Note:
[1] Enhancement mode technology employs positive Vgs, thereby
eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
