Agilent MGA-71543

Low Noise Amplifier with

Mitigated Bypass Switch

Data Sheet

Features

• Lead-free Option Available

• Operating frequency:

0.1 GHz ~ 6.0 GHz

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

• Noise figure: 0.8 dB (NFmin)

• Gain: 16 dB

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.

• Average Idd = 2mA in CDMA

handset

• Bypass switch on chip

Loss = -5.6 dB (Id < 5 µA)

IIP3 = +35 dBm

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.

• Adjustable input IP3: 0 to +9 dBm

• 2.7V to 4.2 V operation

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.

Applications

• CDMA (IS-95, J-STD-008) Receiver

LNA

• Transmit Driver Amp

• W-CDMA Receiver LNA

• TDMA (IS-136) handsets

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.

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

Attention:

Observe precautions for

sensitive devices.

MGA-71543 is used between

duplexers and/or filters.
