SPA 9321-30C Installation and Service Manual

Section 1 General Description

1-1 Introduction

This manual contains information and procedures for installation, operation, and maintenance of
Powerwave’s SPA 9321-30C (Nortel Model No. NTQA50GA) single-channel PCS amplifier. The
manual is organized into six sections as follows:

Section 1. General Description
Section 2. Installation
Section 3. Operating Instructions
Section 4. Principles of Operation
Section 5. Maintenance
Section 6. Troubleshooting

1-2 General Description

The SPA 9321-30C (see figure 1-1) is a single-channel power amplifier that operates in the 60
MHz frequency band from 1930 MHz to 1990 MHz. It is designed for use in an amplifier system
that is modular in design, and is ideally suited for use in GSM/EDGE base stations. The amplifier
is capable of transmitting at 30 watts of power in either GSM or EDGE modulation. All
solid-state, the amplifier is designed to provide trouble-free operation with minimum mainte­nance. The system's modular construction and unique and highly effective operational status and
fault monitoring circuitry help minimize downtime. The turn-on and turn-off sequences of volt­ages are fully automatic, as is overload protection.

Each amplifier module has an I/O connector that allows the host system to monitor the amplifier
module performance. Primary power for the amplifier is –48 Vdc. The amplifier has an integrated
heat sink for cooling.

1-3 Functional And Physical Specifications

Functional and physical specifications for the amplifier are listed in table 1-1.

1-4 Equipment Changes

Powerwave Technologies, Inc. reserves the right to make minor changes to the equipment, in­cluding but not necessarily limited to component substitution and circuitry changes. Changes that
impact this manual may subsequently be incorporated in a later revision of this manual.
