MGA-725M4
Low Noise ­Amplifier with Bypass Switch
In ­Miniature Leadless Package
Data Sheet
Description
Avago Technologies’s ­ MGA­­-725M4 is an economical,
easy-to-use GaAs MMIC Low Noise Amplifier (LNA), which
is designed for an adaptive CDMA receiver LNA and
adaptive CDMA transmit driver amplifier.
The MGA-725M4 features a typical noise figure of 1.4 dB
and 14.4 dB associated gain from a single stage, ­feedback
FET amplifier. The output is internally matched to 50Ω.
The input is optimally internally matched for lowest noise
figure 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 50Ω.
The MGA-725M4 offers an ­ integrated solution of LNA
with adjustable IIP3. The IIP3 can be fixed to a ­desired
current level for the receiver’s 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.
For the CDMA driver amplifier applications, the
MGA-725M4 provides suitable gain and linearity to meet
the ACPR requirement when the handset transmits the
highest power. When transmitting lower power, the
MGA-725M4 can be bypassed, saving the drawing current.
The MGA-725M4 is a GaAs MMIC, processed on Avago’s
cost effective PHEMT (Pseudomorphic High Electron
Mobility Transistor). It is housed in the MiniPak 1412
package. It is part of the Avago Technologies CDMAdvan-
tage RF chipset.
