High Gain, High Linearity Low Noise Amplifier
Avago Technologies’ MGA-13316 is a two stage, easy-to-
use GaAs MMIC Low Noise Amplifier (LNA). The LNA has
low noise with good input return loss and high linearity
achieved through the use of Avago Technologies’ propri-
etary 0.25 Pm GaAs Enhancement-mode pHEMT process.
Minimum matching needed for input, output and the
inter-stage between the two LNA.
It is designed for optimum use between 2.2 GHz to 4 GHz.
For optimum performance at lower frequency from
400 MHz to 1.5 GHz, MGA-13116 is recommended. For
optimum performance at frequency from 1.5 GHz to
2.5 GHz, the MGA-13216 is recommended. All these 3
products, MGA-13116, MGA-13216 and MGA-13316 share
the same package and pinout configuration.

Notes: Enhancement mode technology employs positive gate bias,
thereby eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
