3.2.2 Installation Instructions

Install the HPA8 High Power Amplifier as follows:

1. Unpack the unit.

2. Mount the HPA8 on the rack panel (supplied). To do this, center the unit over the six

mounting holes in the panel and attach with the supplied hardware.

3. Install the HPA8 panel assembly in the rack. Position it so the fan is facing down, and

so that the HPA8 unit goes inside the rack. Secure the assembly to the rack with the

appropriate screws and cup washers.

4. Connect a coax jumper cable to the TX output of the IP8B Base Station Data Trans-

ceiver. Connect the other end to J1 (RF input) on the HPA8.

5. Connect a coax jumper cable to J2 (RF output with harmonic filter) on the HPA8.

Connect the other end to the transmitter IM suppression panel, or other RF device, as

appropriate.

WARNING!

Do not remove the harmonic filter from J2, or operate the HPA8 without

the filter installed. Excessive harmonic emissions may result.

6. Connect the power cable to J3 (power). Attach the other end to the DC power supply

terminals. Black goes to the minus terminal. Red goes to the plus terminal.

7. Connect J4 (control interface). The transmit keying input goes to pin 1 of the PA

connector on the

INVADR

I/O Interface Board. This board is typically mounted on the

back of the rack, and it plugs into the IP8B Base Station Data Transceiver. Optionally,

the high temperature alarm output of J4 may be connected to an external alarm moni-

toring device, or to the ALARM connector on the

INVADR

I/O Interface Board.

8. The HPA8 is installed and ready for use.
