POWER SUPPLY

The model PAM-0126 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-
0126 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. The preamplifier is
turned on by pulling out and
lifting the switch to the on
position, the Power indicator
LED will light. Please allow 15
minutes of warm up time to
allow the preamplifier to
stabilize. The input signal should
normally be at a level of –20
dBm or lower. Signal levels
greater than –20 dBm will drive
the amplifier into compression,
resulting in distortion of the
signal.

CAUTION:

The model PAM-0126

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 -20 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.
