MGA-31489
0.1W High Gain Driver Amplifier
1.5GHz ~ 3GHz
Data Sheet
Description
Avago Technologies MGA-31489 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-314389 is especially ideal for 50
Ω wireless infrastruc-
ture application within the 1.5 GHz to 3 GHz frequency
range applications. With high IP3 and low noise figure and
wideband operation, the MGA-31489 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.

“X” = Date Code character indentifies month of manufacturing
Features
• ROHS compliant
• Halogen free
• High IP3 at low DC bias power[1]
• High gain, with good gain flatness
• Low noise figure
• Advanced enhancement mode PHEMT Technology
• Excellent uniformity in product specification
• SOT-89 standard package
Specifications
At 1.9 GHz, Vd = 5 V, Id = 69 mA (typ) @ 25° C
• OIP3 = 37.3 dBm
• Noise Figure = 1.9 dB
• Gain = 19.5 dB, Gain Flatness (± 50 MHz) = 0.11 dB
• P1dB = 21.9 dBm
• IRL = 17.2 dB, ORL = 10.1 dB
Note:
1. The MGA-31489 has a superior LFOM of 11.9 dB. Linearity Figure of
Merit (LFOM) is essentially OIP3 divided by DC bias power.
