MGA-31589
0.5 W High Gain Driver Ampli er
Data Sheet
Description
Avago Technologies’ MGA-31589 is a 0.5 W, high Gain,
high performance Driver Ampli er MMIC, housed in a
standard SOT-89 plastic package. The device required
simple matching components to achieve optimum per-
formance within speci c 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  gure, the
MGA-31589 may be utilized as a driver ampli er 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-31589’s high gain and high linearity features are
achieved through the use of Avago Technologies’ propri-
etary 0.25 m GaAs Enhancement-mode pHEMT process.

Note: * as blocking capacitor, not required in actual application circuit.
For best performance, MGA-31589 requires only simple input and output matching network. The C3, C4, and L3 act
as the output tuning circuitry for matching and OIP3 optimization. Bandpass network C1,C2, and L1 forms the input
matching network. To bias MGA-31589, a +5 V supply (Vdd) is connected to the output pin thru a RF choke, L2 (which
isolates the inband signal from the DC supply). The low frequency bypass capacitors C6 and C7 help to eliminate low
frequency signals from power supply. Blocking capacitors are required for its input (C8) and output (C9), to isolate the
supply voltage from succeeding circuits. The recommended output tuning is for achieving wideband best OIP3, while
meeting typical speci cations for other parameters.
