RF
PARAMETERS
5.1
TX
LEVEL
The
maximum
output
power
is
+27dBm
(500mW).
The
power
can
be
adjusted
by
1dB
steps.
In
total
there
are
19
steps
meaning
the
minimum
output
power
value
is
+8dBm
that
equals
to
6mW
of
power.
When
using
higher
output
power
levels
the
antennas
VSWR
value
becomes
more
and
more
important
factor.
High
output
power
combined
together
with
antenna
with
poor
VSWR
leads
to
a
situation
where
significant
portion
of
the
power
is
reflected
back
to
the
receiver.

RECEIVER
SENSITIVITY
The
maximum
LBT
sensitivity
is
of
‐
80dBm.
The
receiver
can
handle
+5dBm
of
power
reflecting
back
to
RF_OUT
pin
without
having
a
big
impact
on
the
performance.
Tolerance
to
reflecting
signal
can
be
significantly
increased
using
NUR
‐
05WL2
leakage
cancellation
functionality.
The
receiver
architecture
uses
direct
conversion
and
it
has
an
integrated
AGC
(automatic
gain
controller).
5.3
LEAKAGE
CANCELLATION
The
directional
coupler
of
the
internal
leakage
cancellation
circuitry
separates
transmitted
and
received
signals.
Tuning
the
directional
coupler
increases
the
isolation
between
TX
and
RX
signals.
You
may
tune
the
directional
coupler
using
software;
there
is
an
API
function
of
its
own
for
that
purpose.
