Description
Features
Avago Technologies MGA-31289 is a 0.25W high gain
driver amplifier MMIC with good gain flatness, housed in
a standard SOT-89 plastic package. The device features
high linearity performance, excellent input and output
return loss, and low noise figure. The device can be easily
matched to obtain optimum power and linearity.
•ꢀ ROHS compliant
•ꢀ Halogen free
(1)
•ꢀ High linearity at low DC bias power
•ꢀ High Gain
•ꢀ Good gain flatness
•ꢀ Low noise figure
MGA-31289 is externally tunable to operate within 1.5GHz
to 3GHz frequency range applications. With high IP3, low
noise figure and wideband operation, MGA-31289 may be
utilized as a driver amplifier in the transmit chain and as a
second stage LNA in the receive chain.
•ꢀ Excellent uniformity in product specification
•ꢀ SOT-89 standard package
Specifications
This device uses Avago Technologies proprietary 0.25um
GaAS Enhancement mode PHEMT process.
At 1.9GHz, Vd = 5V, Id = 124mA (typ) @ 25°C
•ꢀ OIP3 = 41.8dBm
Pin connections and Package Marking
•ꢀ Noise Figure = 2dB
•ꢀ Gain = 18.70dB; Gain Flatness (+/-50MHz) = 0.1dB
•ꢀ P1dB = 23.6dBm
12X
•ꢀ IRL = 16.2dB, ORL = 10.3dB
Note:
1. The MGA-31289 has a good LFOM of 14dB. Linearity Figure of Merit
(LFOM) is essentially OIP3 divided by DC bias power.

2 different lots. Future wafers allocated to this product may have
nominal values anywhere between the upper and lower limits.
2. Measurements are made on production test board which represents
a trade-off between optimal Gain, NF, OIP3 and OP1dB. Circuit losses
have been de-embedded from actual measurements.

MGA-31289 is an input and output prematched driver amplifier. To bias MGA-31289, 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 capacitors (C1,
C2 and C3) help to eliminate out of band low frequency signals from the power supply. Blocking capacitors are required
for its input (C7) and output (C8), to isolate the supply voltage from preceding and succeeding circuits. C7 also plays a
part in input tuning to improve input return loss while L1 and C8 help in output matching. The recommended output
tuning is for achieving best OIP3, while meeting typical specifications for other parameters.
