Communication Component Inc.’s Multi-Carrier Amplifier (MCPA) Module is a highly efficient design that is an integral part of CCI’s complete turn-key MCPA system. The MCPA module supports multiple formats such as GSM, EDGE, CDMA, CDMA 1X, EV-DO, and UMTS. The MPCA combines multiple radios on high radio count sites to reduce the required number of feeders without impacting coverage. Additionally, multiple modulation types may be combined in the MCPA providing combining solutions for both 2G and 3G technologies simultaneously. CCI’s MCPA is a key element in upgrading or cositing existing (growth) or new base stations.
Technical Description:
CCI’s MCPA employs a high efficiency Feed Forward design that works with multiple modulation formats simultaneously. Multi-loop architecture reduces the number of components and increases reliability. An internal microprocessor circuit controls all functions, maintains long term (thermal) and short term (distortion) functions, and generates status and alarms. An auto-reboot feature will automatically restart the MCPA module in case of power interruptions. Fans are alarmed and hot swappable, requiring only common tools to change. Module efficiency is greater than 16% due to an advanced Dorrety type architecture which also reduces current consumption during low traffic periods. Intermodulation distortion is extremely low, better than –65 dBc typical, due to a custom pre-linearizer circuit. Dry contact alarms are also provided for simple interface to existing base station alarm reporting circuits.
