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.

Pin Configuration and Package Marking

4.0 x 4.0 x 0.85 mm

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.
