2. Interface Description
As shown in section 8.3, the HPA8 has the following interface connections:
J1 RF input. Typically connects to the IP8B Base Station Data Transceiver.
J2 RF output. Typically connects to the antenna system components in the rack.
WARNING!
Do not remove the harmonic filter, or operate the HPA8 without the
filter installed. Excessive harmonic emissions may result.
J3 DC power connector. Plugs into a 13.8 volt (nominal), 25 amp (or greater) DC
power supply.
J4 Control interface connector. The transmit keying input connects to the IP8B
Base Station Data Transceiver via an
INVADR
I/O Interface Board mounted
on the rack. The high temperature alarm output may be connected to an alarm
monitoring system, or to the ALARM connector on the
INVADR
I/O Interface
Board.
3. Installation
3.1 Unpacking
Upon opening the carton, carefully inspect the amplifier for any signs of shipping
damage. If there is evidence of damage, file a claim immediately with the carrier and
contact your dealer. Keep the original shipping container for verification of damage after
filing the claim.
3.2 Installation
When planning an HPA8 High Power Amplifier installation, be sure to consider the
amount of air flow available in the amplifier’s mounting location. Also make sure that
adequate space exists for the routing of the RF, power, and control cables.
Note: RF, power, and control cables should be provided with service loops. This makes
it easier to remove and install the unit in the future.
For long life, be sure to observe the following installation precautions:
•
Allow at least 3” clearance at each end of the heatsink for good airflow.
•
Install the unit with the fan side closest to the bottom of the rack.
•
Do not allow cables or other components to obstruct the airflow.
