MGA-31589
0.5 W High Gain Driver Amplifier
Data Sheet
Description
Avago Technologiesâ MGA-31589 is a 0.5 W, high Gain,
high performance Driver Amplifier MMIC, housed in a
standard SOT-89 plastic package. The device required
simple matching components to achieve optimum per-
formance within specific 100 to 200 MHz bandwidth.
MGA-31589 is especially ideal for wireless infrastructure
applications that operate within the 450 MHz to 1.5 GHz
frequency range. With high IP3 and low noise figure, the
MGA-31589 may be utilized as a driver amplifier in the
transmit chain and as second or third stage LNA in the re-
ceive chain. For optimum performance at higher frequen-
cy from 1.5 GHz to 3.0 GHz, MGA-31689 is recommended.
MGA-31589âs high gain and high linearity features are
achieved through the use of Avago Technologiesâ propri-
etary 0.25 mm GaAs Enhancement-mode pHEMT process.
