MGA-31389
0.1W 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 Ω 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 mm
GaAs Enhancement mode PHEMT process.
