MGA-31189
0.25W High Gain Driver Amplifier
50 – 2000 MHz
Data Sheet
Description
Avago Technologies MGA-31189 is a 0.25W high gain
with good gain flatness Driver Amplifier MMIC, 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.
MGA-31189 is externally tunable to operate within 50MHz
to 2GHz frequency range applications. With high IP3, low
noise figure and wideband operation, the MGA-31189 can
be utilized as a driver amplifier in the transmit chain and
as a second stage LNA in the receive chain.
This device uses Avago Technologies proprietary 0.25um
GaAs Enhancement mode PHEMT process.

Features
• ROHS compliant
• Halogen free
• Very high linearity at low DC bias power [1]
• High Gain
• Good gain flatness
• Low noise figure
• Excellent uniformity in product specification
• SOT-89 standard package
Specifications
At 0.9GHz, Vdd = 5V, Idd = 111mA (typ) @ 25°C
• OIP3 = 42dBm
• Noise Figure = 2.0dB
• Gain = 21dB; Gain Flatness (+/-50MHz) = 0.1dB
• P1dB = 24 dBm
• IRL = 15.6dB, ORL = 12.8dB
Note:
1. The MGA-31189 has a superior LFOM of 14.5dB. Linearity Figure of
Merit (LFOM) is essentially OIP3 divided by DC bias power.
