Description
Agilent’s MGA-72543 is an economi-
cal, 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-72543 features a mini-
mum noise figure of 1.4 dB and
14 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-72543 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 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-72543
provides suitable gain and linearity
to meet the ACPR requirements
when the handset transmits the
highest power. When transmitting
lower power, the MGA-72543 can
be bypassed, saving the drawing
current.
The MGA-72543 is a GaAs MMIC,
processed on Agilent’s cost effec-
tive PHEMT (Pseudomorphic High
Electron Mobility Transistor). It is
housed in the SOT343 (SC70 4-lead)
package, and is part of the Agilent
Technologies CDMAdvantage RF
chipset.
