MCPS2135 System Operation 3
2001 Spectrian Corporation. All rights reserved.
Modulation Formats
The MCPS2135 can amplify any number of signal carriers using AMPS, CDPD,
IS-136 TDMA, IS-136HS GSM, IS-136HS EDGE, or IS-95 CDMA modulation
up to the maximum rated system output power.
Modularity
The MCPS2135 family is designed for operation with 1 to 4 amplifier modules,
each providing up to 135 Watts of RF output power (exclusive of combining
losses).
Mounting Configurations
The MCPS2135 amplifier systems are available in a variety of configurations.
Mounting kits are available for installation in 19-inch, 23-inch, 600mm, 24-inch,
or 25-inch equipment racks. Multi-module shelves are 8 RU (14 in.) high. Single
module shelves are 3 RU (5.25 in.) high.
Peripheral Products
Spectrian offers optional products to assist in base station configuration and set-
up. Among these products are multi-port RF combiners, bandpass filters,
preamplifiers, and AC/DC power rectifiers. Please consult with the factory or
sales for more information on these peripheral products.
RF Interfaces
The Spectrian MCPS2135 has a single RF input for combined input signals, and a
single RF output to the transmit filter. There is also a single module configuration
with three input connectors combined within the amplifier and a single output
connector.
Alarms and Control
The MCPS2135 system provides visual status information through front-panel
LED indicators. Status information is also transmitted via a front-panel RS-232
port using Spectrian’s optional Graphical User Interface program.
The MCPS2135 can also be optionally equipped with additional alarm and control
interfaces, including dry-contact or TTL alarm connections RS-232 or RS-422
interfaces to network operations and administration systems.
The MCPS2135 is designed to enable system maintenance without removing the
amplifier from service. In multi-module (high power) systems, the RF modules
can be hot-swapped during operation without affecting calls in process. The
Amplifier Management Module (AMM) can be easily replaced in the field. The
amplifier modules are designed so the cooling fans can be replaced in the field by
qualified service technicians, greatly reducing service shipping costs and turn-
around time.
