MGA-14516
High Gain, High Linearity Active Bias Low Noise Amplifier
Data Sheet
Description
Avago Technologies’ MGA-14516 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
Technologies’ proprietary 0.5um and 0.25um GaAs En-
hancement-mode pHEMT process. Both LNAs have an
extra feature inside 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 1.4GHz to 2.7GHz.
For optimum performance at lower frequency from
400MHz to 1.5GHz, the MGA-13516 is recommended.
Both MGA-13516 & MGA-14516 share the same package
and pinout.

Notes:
Package marking provides orientation and identification “14516” is the
Product Identification, “YYWW” is the Date Code, “XXXX” is the last 4
digits of the lot number.
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.
ESD Machine Model = 40 V
