LMH2120UM Linear RMS Power Detector with 40 dB Dynamic Range ic
APPLICATION INFORMATION
The
LMH2120
is
a
40
dB
Linear
RMS
power
detector
particularly
suited
for
accurate
power
measurements
of
modulated
RF
signals
that
exhibit
large
peak-to-average
ratios
(PAR’s).
The
RMS
detector
implements
the
exact
definition
of
power
resulting
in
a
power
measurement
insensitive
to
high
PAR’s.
Such
signals
are
encountered,
e.g,
in
LTE
and
W-CDMA
applications.
The
LMH2120
has
an
RF
frequency
range
from
50
MHz
to
6
GHz.
It
provides
an
output
voltage
that
relates
linearly
to
the
RF
input
power
in
volt.
Its
output
voltage
is
highly
insensitive
to
temperature
and
supply
variations.
TYPICAL
APPLICATION
The
LMH2120
can
be
used
in
a
wide
variety
of
applications
like
LTE,
W-CDMA,
CDMA
and
GSM.
This
section
discusses
the
LMH2120
in
a
typical
transmit
power
control
loop
for
such
applications.
Transmit-power-control-loop
circuits
make
the
transmit-power
level
insensitive
to
power
amplifier
(PA)
inaccuracy.
This
is
desirable
because
power
amplifiers
are
non-linear
devices
and
temperature
dependent,
making
it
hard
to
estimate
the
exact
transmit
power
level.
If
a
control
loop
is
used,
the
inaccuracy
of
the
PA
is
eliminated
from
the
overall
accuracy
of
the
transmit
power
level.
The
accuracy
of
the
transmit
power
level
now
depends
on
the
RF
detector
accuracy
instead.
The
LMH2120
is
especially
suited
for
transmit-power
control
applications,
since
it
accurately
measures
transmit
power
and
is
insensitive
to
temperature,
supply
voltage
and
modulation
variations.
