SECTION II
Installation
2.1 Incoming Inspection WARNING!
Do not apply power until you have read Sections II and III and you have
performed all specified procedures. If you fail to observe this warning,
damage to the equipment and/or bodily injury may result.
The power amplifier has been mechanically and electrically inspected prior to
shipment. If the equipment has been damaged or if electrical performance is
not within specification, notify the carrier and OPHIR RF immediately.
2.2 Preparation For Use
2.2.1 Power Requirements
The power amplifier requires a power source of 100 – 240 VAC, 50/60
Hz capable of delivering 200 Watts. Turn off the front panel ‘ON/OFF’
switch before connecting the AC power source.
2.2.2 Earthing
Earthing is achieved simultaneously with connection of the AC power
cords to a properly grounded power source.
2.2.3 Load Requirements
The power amplifier requires a load, antenna, or dummy load with a 50-
Ohm nominal impedance.
CAUTION!
Make this external load connection before applying any power to the
equipment.
2.2.4 Cable Connections
The AC power cable connection is made at the rear of the power
amplifier via the receptacle connector. RF connections for Input and
Output are made at the front via Type-N connectors. (Refer to Figure 2)

SECTION III
Operation
3.1 Introduction
This section describes the operating controls and procedures of the power
amplifier.
3.2 Statement Against Unspecified Use
This amplifier must be used as specified by the manufacturer. Use of this
equipment in any way not specified by the manufacturer may result in bodily
injury and/or damage to the equipment.
3.3 Controls, Indicators, and Connectors
When set to ‘ON’, the ON/OFF switch will light indicating that AC power is
present. The RF INPUT and OUTPUT connections are located on the front of
the power amplifier. Refer to figure 2 and the following discussion for the
location and functional description of all controls, indicators, and connectors.
3.4 Basic Operating Procedures NOTE!
The operation of the power amplifier is passive; that is, after an External Load
and Input power have been applied, no procedures other than turn off are
required.
3.5 Before Turn On CAUTION!
Do not obstruct the airflow at the front and rear of the power amplifier. If
you do not verify that this equipment has an unobstructed airflow, you
may cause this equipment to overheat or otherwise impair its operation.
Perform the following preliminary procedures before energizing the equipment:
a. Check that the ON/OFF switch is set to the ‘OFF’ position.
b. At the rear of the RF power amplifier, verify that the AC cord is properly
inserted into the receptacle connector.
c. Verify that 50 ohm loads are connected to the RF Input and Output ports.
3.6. Turn On
Perform the following procedures to energize the equipment:
a. Set the ON/OFF switch to the ‘ON’ position. Verify that the green switch
lamp is lit.
b. Apply RF power.

OM_5100F 12/12/01 Page 9 of 14
CAUTION!
To maintain specified performance and retain certain operating
characteristics, RF input power should not exceed +10 dBm.
3.7. Operation
3.7.1 ON/OFF Switch
In the ‘ON’ position, AC power is supplied to the power amplifier.
3.7.2 ON/OFF Switch Lamp
Lights to indicate the distribution of AC power throughout the power
amplifier.
3.7.3 TEMP. FAULT Indicator
Lights at an internal temperature exceeding 80º C with the amplifier
turning off DC bias voltage to the main amplifiers’ modules. DC bias
voltage will automatically return at temperatures below 75º C.
3.8 Turn Off. WARNING!
In the event of ANY power failure, whenever possible and practical, it is
advisable to reset the ON/OFF switch on the front panel to the “OFF”
position before you reconnect AC power to the power amplifier. This is to
prevent any possible electrical damage to the amplifier, due to the initial
power surge, once power is restored.
Turn off the RF power amplifier by first lowering or removing the RF Input drive
level and then placing the ON/OFF switch in the ‘OFF’ position.
