3.3.2.1.1 Multi-Carrier Power Amplifier (MCPA) Modules
The MCPA Module is the heart of the mBSC RUM Enclosure. The MCPA Module boosts the BTS forward
link transmission signal. Operating on28VDC input, the MCPA Module produces 5W composite RF power
for each band (measured at output of the antenna combiner).
The mBSC system provides linear amplification of multi-carrier, mixed-mode signals in the 700MHz,
850MHz, 1900MHz, 2100MHz and 2600MHz frequency bands with the respective RU’s.
3.3.2.1.2 Duplexer
The duplexer is used to make the bi-directional signals into simplex signals and provides sufficient isolation
3.3.2.1.3 CPU(Central Processing Unite)
The CPU provides communications and monitors with power amplifier module or other functional module.
3.3.2.2 Mounting
The single-band RUM enclosure is plug in REMOTE NODE multi-slot chassis.
3.3.2.3 RF Connection
The RF signal connections with the single-band enclosure are supported through two QMA female coaxial
connectors and one N female connector. The two QMA female connectors are used for coaxial cable
connection (RF jumper) of the Tx and Rx RF signals between the RTM enclosure and the single-band RUM
enclosure. The N female connector is used for coaxial cable connection of the amplified duplex Tx/Rx RF
signal to the BCM enclosure.
3.3.2.4 Cooling
The single-band RUM enclosure is cooled by cooling fans in the bottom of the casing. A minimum of 200mm
(7.87 inches) of clearance space must be provided on both the top and the bottom sides of the Remote
Node for air convection.
