Chapter 5 - Specifications
Chapter 1
Product Description
1.3 Product Description
The MCPA shown in Figure 1-1 is a linear, feed-forward multi-carrier power amplifier that operates in
a 60 MHz frequency band from 1930 MHz to 1990 MHz with an instantaneous bandwidth of 40 MHz.
The instantaneous bandwidth is the maximum frequency band in which any two or more signals can
occupy. The instantaneous bandwidth of the MCPA is set automatically.
The MCPA is modular in design and ideally suited for use in GSM, EDGE, CDMA, and W-CDMA base
stations. The MCPA provides a gain of 63 dB to supply a 160 watt output. Refer to Figure 1-2 for the
MCPA functional block diagram. Refer to Chapter 5 for the MCPA specifications.
1.4 Functional Description
The MCPA is a self-contained module typically operated in parallel with other identical MCPAs as part
of a subrack assembly.
The MCPA consists of the following major functions:
• Preamplifier
• Main and error amplifiers
• Feed-forward loop control circuits
• Pilot tone generator
• Controller
