INTRODUCTION
A.H. Systems' Preamplifier line is an excellent choice with a rugged design, no hassles with soldering your own power leads and they improve overall system sensitivity by at least 20 dB. All of the Preamplifiers come with a 12-volt (or 15-volt) DC regulated power source. A low voltage indicator confidently allows you to power the amplifier with your own external 12­volt DC battery. This makes it a convenient choice for field measurements.
INTENDED PURPOSES
This equipment is intended for general laboratory use in a wide variety of industrial and scientific applications and is designed to be
Model: PAM-0118
FEATURES:
Wide Bandwidth (20 MHz – 18 GHz) Low Noise, High Gain Individually Calibrated Low VSWR Improve Overall System Sensitivity Rugged Design
used in the process of generating, controlling and measuring high levels of electromagnetic Radio Frequency (RF) energy. Therefore, the output of the amplifier must be connected to an appropriate load such as an antenna, field­generating device or receiver. It is the responsibility of the user to assure that the device is operated in a location which will control the radiated energy such that it will not cause injury and will not violate regulatory levels of electromagnetic interference.
HAZARDOUS RF VOLTAGES
The RF output connector should be connected to a load before AC power is applied to the amplifier.

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 PAM­0118 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.
Annual recalibration is recommended to ensure reliable and repeatable performance. A.H. Systems experienced technicians can recalibrate almost any type or brand of antenna.
