Description
Agilent Technologies鈥檚
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 50鈩? The input is optimally
internally matched for lowest
noise figure into 50鈩? 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 50鈩?
Simplified Schematic
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鈥檚 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-725M4
provides suitable gain and linear-
ity 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 Agilent鈥檚 cost
effective PHEMT (Pseudomorphic
High Electron Mobility Transistor).
It is housed in the MiniPak 1412
package. It is part of the Agilent
Technologies CDMAdvantage RF
chipset.
