MGA-31289
0.25W High Gain Driver Amplifier
1500 - 3000 MHz
Data Sheet
Description
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.
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.
This device uses Avago Technologies proprietary 0.25um
GaAS Enhancement mode PHEMT process.
