Agilent MGA-71543  
Low Noise Amplifier with  
Mitigated Bypass Switch  
Data Sheet  
Features  
• Operating frequency:  
0.1 GHz ~ 6.0 GHz  
• Noise figure: 0.8 dB (NFmin)  
• Gain: 16 dB  
• Average Idd = 2mA in CDMA  
handset  
The MGA-71543 offers an inte-  
grated solution of LNA with  
adjustable IIP3. The IIP3 can be  
fixed to a desired current level for  
the receiver’s linearity require-  
ments. 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.  
Description  
• Bypass switch on chip  
Loss = -5.6 dB (Id < 5 µA)  
IIP3 = +35 dBm  
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.  
• Adjustable input IP3: 0 to +9 dBm  
• 2.7V to 4.2V operation  
Applications  
• CDMA (IS-95, J-STD-008) Receiver  
LNA  
The MGA-71543 features a  
• Transmit Driver Amp  
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.  
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.  
• W-CDMA Receiver LNA  
• TDMA (IS-136) handsets  
Surface Mount Package  
SOT-343/4-lead SC70  
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  
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.
