Modularity
The MCPS2000 family is designed for operation with 1 to 4 amplifier modules, each
providing 100 Watts of RF output power (up to 90 Watts effective output after
combining losses).

Installation
The MCPS2000 housing is an 8RU shelf. Mounting kits are available for installation
in 23-inch, 600mm, 24-inch, or 25-inch equipment racks.

RF Interfaces
It has a single RF input for the combined input signals, and a single RF output to the
transmit filter.

Alarms and Control
The MCPS2000 provides status information through front-panel LED indicators and
an RS-232 status port. Status information can be viewed through a front-panel RS-
232 port using either a VT-100 terminal emulation program or Spectrian’s Graphical
User Interface program.

The MCPS2000 can also be optionally equipped with additional alarm and control
interfaces, including dry-contact or TTL alarm connections and RS-485 or RS-422
interfaces to network operations and administration systems.

Reliability
The MCPS2000 is designed to enable system maintenance without removing the
amplifier from service. The amplifier and system control modules can be hot-
swapped during operation without affecting calls in process. The amplifier modules
are designed so the cooling fans can be refit in the field by qualified service
technicians, greatly reducing service shipping costs and turn-around time.

Systems
Modules
A fully-equipped MCPS2000 consists of a rack-mounted shelf containing up to four
RF modules, an Alarm Management Module, and an internal divider/ combiner.

RF modules
The RF modules are ultra-linear amplifiers optimized for high power amplification
of cellular signals. After combining losses, each RF module provides up to 90 Watts
of RF output power.

Divider/Combiner
The divider/combiner allows the four RF modules to function as a single system.
The divider/combiner has an active architecture, which automatically reconfigures to
minimize combining losses if a RF module should fail.
