MGA-31816
0.1 W High Linearity Driver Amplifier
Data Sheet
Description
Avago Technologies MGA-31816 is a high linearity driver
MMIC Amplifier housed in a standard QFN 3X3 16 lead
plastic package. It features high gain, low operating
current, good noise figure with good input and output
return loss. Power consumption can be further reduced
by reducing the quiescent bias current using two external
bias resistors. The device can be easily matched at different
frequencies to obtain optimal linearity performance at
those frequencies.
MGA-31816 is especially ideal for 50 W wireless infrastruc-
ture application operating from 1.5 GHz to 4 GHz frequency
range applications. With the high linearity, excellent gain
flatness and low noise figure the MGA-31816 may be
utilized as a driver amplifier in the transmit chain and as a
second stage LNA in the receiver chain.
This device uses Avago Technologies proprietary 0.25 mm
GaAs Enhancement mode PHEMT process.
