Description
Features
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
•ꢀ ROHS compliant
•ꢀ Halogen free
[1]
•ꢀ High IP3 at low DC bias power
performance. The device can be easily matched to obtain •ꢀ High gain, with good gain flatness
desired performance.
•ꢀ Low noise figure
MGA-314389 is especially ideal for 50 Ωwireless 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.
•ꢀ 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
This device uses Avago Technologies proprietary 0.25 mm
GaAs Enhancement mode PHEMT process.
•ꢀ Noise Figure = 1.9 dB
Pin connections and Package Marking
•ꢀ 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.

For best performance, MGA-31489 is an input and output prematched driver amplifier. To bias MGA-31489, a +5V supply
(Vdd) is connected to the output pin through a RF choke, L1 (which isolates the inband signal from the DC supply).
The bypass capacitor helps to eliminate out of low band frequency signals from the power supply, C2 and C3. Blocking
capacitors are required for its input (C7) and output (C8), to isolate the supply voltage from preceeding and succeeding
circuits. C7 and L3 also play a part in input tuning to improve input return loss while L1 and C8 help in tuning output. The
recommended output tuning is for achieving best OIP3, while meeting typical specifications for other parameters.
