GENERAL DESCRIPTION
1—1. INTRODUCTION
This manual contains information and procedures for installation, operation, and maintenance of
Powerwave‘s multicarrier cellular amplifier systems. The manual is organized into five sections as
follows:
Section 1. General Description
Section 2. Installation
Section 3. Operating Instructions
Section 4. Principles of Operation
Section 5, Maintenance
1-2. GENERAL DESCRIPTION
The MCA9503-60 is a linear, feed-forward power amplifier that operates in the 25 MHz frequency
band from 869 MHz to 894 MHz. The amplifier can simultaneously transmit multiple frequencies,
with better than -65 dBc third order intermodulation distortion (IMD). The amplifier system is
modular In design, and is ideally sulted for use In AMPS/TDMAICDMA base stations. The plug-in
Model MCA9503-60 amplifier modules can each provide 60 watts of power and function
completely independently of each other. The amplifier modules are designed for parallel
operation to produce high peak power output and backup redundancy for remote applications.
The system Is housed In the MCSSSOS-4 subrack which holds up to four MCA9503A60 amplifiers
to produce up to 200 watts output (figure 1-1). All solid-state, the system is designed to provide
trouble-free operation with minimum maintenance. The system‘s modular construction and unique
and highly effective LED-based operational status and fault indicators help minimize down-time.
The turn-on and turn-off sequences of voltages are fully automatic, as is overload protection and
recycling. Inadvertent operator damage from front panel manipulation is virtually impossible,
The M086503—4 subrack contains an RF power splitter/combiner and a summary logic module
that monitors the functional status of all plug-in amplifiers. The rear panel of the subrack has the
system RF I/O connectors. an RF output sample connector, and DC power Input terminals. The
front panel of each amplifier module has unit level status/fault indicators and a power onloff circuit
breaker. Primary power for the amplifier system is +27 Vdc. Cooling for each plug-in amplifier
module is provided by two fans mounted on the front and one on the rear of the module The fans
draw outside air through the front of the module and exhaust hot air out through the rear of the
module.
1-3. FUNCTIONAL AND PHYSICAL SPECIFICATIONS
Functional and physical specifications for the amplifier system are listed in table 1-2.

Powemave Technologies recommends mat proper AC line conditioning and surge suppression
be provided on the primary AC input to the s27 Vdc power source, All electrical service should be
installed in accordance with the National Electrical Code, any applicable state or local codes, and
good engineering practice, Special consideration should be given to lightning protection of all
systems in View of the vulnerability of most transmitter sites to lightning. Lightning arrestors are
recommended in the service entrance Slraight, short ground runs are recommended. The
electrical service must be well grounded.
Each amplifier system should have its own circuit breaker, so a failure in one does not shut off the
whole installation. Circuit breakers should be thermal type, capable of handling an inrush current
of 125 Amps. in a load center with a master switch.
