POWER SUPPLY
The model PAM-0118 is
supplied with an external power
supply that can be used on
110/120/220/240 VAC, 50/60
Hz, and supplies 15.0 VDC at
180 mA. The power supply has
a standard AC input connector
and uses a 2.5mm coax output
connector. An optional battery
source may be used for this unit.
GENERAL USE INSTRUCTIONS
Operation of the model PAM-
0118 low noise amplifier is quite
simple. The unit is turned on by
first plugging the phone type
plug from an external power
supply into the power input
connector. The power supply is
then plugged into the
appropriate line voltage supply.
The input signal is connected to
the jack marked “INPUT”. The
output signal is taken from the
jack marked “OUTPUT” and fed
to the desired amplifier or test
equipment. When the
preamplifier is turned on the
power indicator LED will light.
Please allow 15 minutes of
warm up time to allow the
preamplifier to stabilize. The
input signal should always be at
a level of –30 dBm or lower.
Signal levels greater than –30
dBm will drive the amplifier into
compression, resulting in
distortion of the signal.
CAUTION:
The model PAM-0118
amplifier is not critical in
regards to source and load
VSWR and will remain
unconditionally stable with
any magnitude and phase of
source and load VSWR.
However, input signals
greater than +10 dBm can
damage the amplifier.
MAINTENANCE
Annual recalibration is
recommended to ensure reliable
and repeatable performance.
A.H. Systems experienced
technicians can recalibrate
almost any type or brand of
antenna.
