4.1 Cabinet Overview
This section contains a functional description of the Powerwave OPAF Outdoor Multi-Carrier Power Amplifier
(MCPA) System. Refer to the system block diagrams below.
A complete OPAF system consists of a combined three-sector configuration that includes six G3S-1900-125
MCPA, 125-Watt amplifiers and three 4 KW (148-Amp), six Duplexer LNA (DLNA) assemblies, a System Interface
Module (SIM), four 220 VAC AC to +27 VDC rectifiers, a Low Voltage Disconnect (LVD) assembly, four backup
batteries and one outdoor enclosure.
The cabinet is equipped with four lifting bosses on the top panel. The lifting bosses are designed to carry six-times
the weight of the cabinet and its full contents, providing the weight is evenly distributed between the four lifting
bosses.
The cabinet provides easy cable and conduit access, to eliminate the need for external cable protective materials.
This eases the installation and maintenance of the cabinet. The cabinet is designed for ease of maintenance with
most modules and cables accessible either from the front of the cabinet, or side panel maintenance ports.
The cabinet provides 3 110 VAC GFCI courtesy outlets. 2 are incorporated in the front and rear light fixtures at the
top of the cabinet, the third is located inside the AC panel. 10 amps of service is available for these three outlets.
