MGA-785T6
Low Noise Ampliï¬er with Bypass Switch
Data Sheet
Description/Applications
The MGA-785T6 is an easyâtoâuse GaAs MMIC Low Noise
Ampliï¬er (LNA) that oï¬er excellent linearity and low noise
ï¬gure for application from 0.1 to 1.5 GHz. The device is
housed in Ultra Thin Small Leadless Package (UTSLP) with
0.4mm package thickness.
The MGA-785T6 features a typical noise ï¬gure of 1.5 dB
and 15.7 dB associated gain from single stage, feedback
FET ampliï¬er. The output is internally matched to 50Ω.
The input is optimally internally matched for lowest noise
ï¬gure into 50Ω. The input may be additionally externally
matched for low VSWR through the addition of a single
series inductor. When set into the bypass mode, both
input and output are internally matched to 50 Ω.
The MGA-785T6 oï¬ers an integrated solution of LNA with
adjustable IIP3. The IIP3 can be ï¬xed to a desired current
level for the receiverâs linearity requirements. The LNA has
a bypass switch function, which sets the current to zero
and provides low insertion loss. The bypass mode also
boosts dynamic range when high level signal is being
received.
