MGA-13516
High Gain, High Linearity, Active Bias,
Low Noise Amplifier
Data Sheet
Description
Avago Technologies’ MGA-13516 is a two stage, easy-to-
use GaAs MMIC Low Noise Amplifier (LNA) with active bias.
The LNA has low noise with good input return loss and
high linearity achieved through the use of Avago Tech-
nologies’ proprietary 0.5um and 0.25um GaAs Enhance-
ment-mode pHEMT process. Both LNAs inside have extra
feature that allows a designer to adjust supply current.
The first stage has an additional feature where the gain
can be adjusted externally without affecting noise figure.
Minimum matching needed for input, output and the
inter-stage between the two LNA.
It is designed for optimum use between 400MHz to
1.5GHz. For optimum performance at higher frequency
from 1.4GHz to 2.7GHz, the MGA-14516 is recommended.
Both MGA-13516 & MGA-14516 share the same package
and pinout.

Note:
1. Enhancement mode technology employs positive Vgs, thereby
eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
Attention: Observe precautions for
handling electrostatic sensitive devices
