Description
Agilent’s MGA-71543 is an
economical, easy-to-use GaAs
MMIC Low Noise Amplifier (LNA),
which is designed for adaptive
CDMA and W-CDMA receiver
systems. The MGA-71543 is part
of the Agilent Technologies
complete CDMAdvantage RF
chipset.
The MGA-71543 features a
minimum noise figure of 0.8 dB
and 16 dB available gain from a
single stage, feedback FET
amplifier. The input and output
are partially matched, and only a
simple series/shunt inductor
match is required to achieve low
noise figure and VSWR into 50Ω.
When set into the bypass mode,
both input and output are inter-
nally matched through a mitigative
circuit. This circuit draws no
current, yet duplicates the in and
out impedance of the LNA. This
allows the system user to have
minimum mismatch change from
LNA to bypass mode, which is
very important when the
MGA-71543 is used between
duplexers and/or filters.
The MGA-71543 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 provides low
insertion loss at zero current. The
bypass mode also boosts dynamic
range when high level signal is
being received.
The MGA-71543 is designed for
CDMA and W-CDMA receiver
systems. The IP3, Gain, and
mitigative network are tailored to
these applications where filters
are used. Many CDMA systems
operate 20% LNA mode, 80%
bypass. With the bypass current
draw of zero and LNA of 10 mA,
the MGA-71543 allows an average
2 mA current.
The MGA-71543 is a GaAs MMIC,
processed on Agilent’s cost
effective PHEMT (Pseudomorphic
High Electron Mobility Transistor
Technology). It is housed in the
SOT343 (SC70 4-lead) package.
