MGA-31716
0.1 W High Linearity Driver Amplifier
Data Sheet
Description
Avago Technologies MGA-31716 is a high linearity driver
MMIC Amplifier housed in a standard QFN 3X3 16 lead
plastic package. It features high gain, low operating
current, low 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-31716 is especially ideal for 50 : wireless infrastruc-
ture application operating from DC to 2 GHz frequency
range. With the high linearity, excellent gain flatness and
low noise figure the MGA-31716 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 Pm
GaAs Enhancement mode PHEMT process.
