MGA-30489
0.25W Driver Amplifier
Data Sheet
Description
Avago Technologies’s MGA-30489 is a 0.25W highly
dynamic range Driver Amplifier MMIC, housed in a SOT-89
standard plastic package. The device features excellent
input and output return loss, highly linear performance.
The device can be easily matched to obtain optimum
power and linearity.
MGA-30489 is especially ideal for 50Ω wireless infrastruc-
ture application such as Cellular/PCS/W-CDMA/WLLand
and new generation wireless technologies systems in the
250MHz to 3GHz frequency range applications. With
high IP3 and low noise figure and wideband operation,
the MGA-30489 may be utilized as a driver amplifier in the
transmit chain and as a second stage LNA in the receive
chain.

Features
• ROHS compliant
• Halogen free
• Very high linearity at low DC bias power^[1]
• Low noise figure
• High OIP3
• Advanced enhancement mode PHEMT Technology
• Excellent uniformity in product specification
• SOT-89 standard package
Specifications
At 1.9GHz, Vdd = 5V, Idd = 97mA (typ) @ 25°C
• OIP3 = 39 dBm
• Noise Figure = 3 dB
• Gain = 13.3 dB
• P1dB = 23.3 dBm
• IRL = 15dB, ORL = 14.5dB
Notes:
1. The MGA-30489 has a superior LFOM of 13dB. Linearity Figure of
Merit (LFOM) is essentially OIP3 divided by DC bias power. There are
few devices in the market that can match its combination of high
linearity and low noise figure at the low DC bias power of 5V/97mA.
