AWS (UMTS/HSPA) 120W Multi-Carrier Power Amplifier
CCI Model Number MCPA-2100-125
USER’S GUIDE
Product Description:
MCPA-2100-125 AWS (UMTS/HSPA) 120W Multi-Carrier Power Amplifier:
The CCI AWS (UMTS/HSPA) 120W Multi-Carrier Power Amplifier (MCPA) Module consists of a
Digital Pre-Distortion power amplifier, capable of generating a minimum 120 Watt UMTS/HSPA
signal.
Operation Description:
The MCPA-2100-125 Multi-Carrier Power Amplifier is designed to supply a nominal output power
level of 120 Watts (+50.8 dBm). Although the gain of the MCPA is fixed, the output can be
adjusted by setting the input power level.
Operation and Installation Instructions:
The following instructions should be followed when installing the unit in service:
• Apply a 30-34 VDC input voltage to the DC Input connector of the AWS 120W Multi-
Carrier Power Amplifier Module.
• Insure that the DC Source is capable of delivering up to 15 Amps at 32 VDC.
• Apply a UMTS/HSPA signal up to +9 dBm to the RF Input port of the Multi-Carrier Power
Amplifier Module.
Note: “System Level” usage (see typical site installation block diagram on page 2) is
based on the input signal from the BTS being +46 dBm. If a directional coupler with a -30
dB forward coupled port is used as the input to the AWS 120W MCPA Module, then the
signal level out of the coupled port is +16 dBm. Finally, there is a variable attenuator set
to 6 dB is placed prior to the MCPA Module. This drops the input level to the Amplifier to
approximately +9 dBm including the Attenuator and any Cable losses. Note: A variable
attenuator is called out in case the coupler used has a different value for its coupled port,
or the cable losses vary. Remember, the maximum input to the Amplifier is +9 dBm.
• The Multi-Carrier Power Amplifier Module will provide approximately 42 dB or less of RF
Gain.
• Check the RF Output to insure proper output power is present.
{Approximately 125 Watts (+51 dBm)}
• Adjust the input power level to insure the output power level is in compliance with the
values indicated in the table on page 2.
• Install the Alarm Connector to the Alarm Output connector of the Multi-Channel Power
Amplifier Module.
