MGA-31389

High Gain Driver Amplifier

50MHz ~ 2GHz

Data Sheet

Description

Avago Technologies MGA-31389 is a high performance

Driver Amplifier MMIC, housed in a standard SOT-89 plastic

package. The device features flat high gain with excellent

input and output return loss, as well as superior linearity

performance. The device can be easily matched to obtain

desired performance.

MGA-31389 is especially ideal for 50 : wireless infrastruc-

ture application within the 50 MHz to 2GHz frequency

range applications. With high IP3 and low noise figure and

wideband operation, the MGA-31389 may be utilized as

a driver amplifier in the transmit chain and as a second

stage LNA in the receiver chain.

This device uses Avago Technologies proprietary 0.25 Pm

GaAs Enhancement mode PHEMT process.
