Power Amplifiers or Multi Carrier Power Amplifiers (MCPA) are critical radio frequency components of wireless network systems, typically representing 20-40 percent of the total cost of a base-station or the radio transmitter. There are a variety of wireless standards associated with 2G, 2.5G, 3G and 4G wireless systems and power amplifiers are designed for each, with frequencies ranging from 450MHz to 2.7GHz. 
Typically, power amplifiers are specifically designed to match the air interface employed for the cellular base-station. However, it is becoming increasingly popular to deploy amplifiers that support multiple air interfaces simultaneously on a frequency band. As service carriers migrate to air interfaces that support high speed data, transceiver elements that support these new standards are added to base station equipment. In order to save on equipment costs, service carriers are attempting to re-use as much of the base station equipment as possible while running multiple standards. 
Antenna and feed-line sharing has been used in the past.To extend this notion to electronics within the base station including filters, cables and power amplifiers. The Multi-Carrier Power Amplifier (MCPA) specifically addresses this issue. It is designed to meet the stringent air interface requirements associated with 2G, 2.5G, 3G and 4G base-station wireless systems. 
MCPA are specially designed and capable to amplify the multiple numbers of carriers without degrading the network performance. Feed forward technology and pre-distortions circuit provide highly linear output which can achieve -65 to-70dBc IMD. IMD suppression is most important when it comes multiple carriers and high output power.MCPA can consists as an option a built-in bypass circuit and if any fault in the equipment trigger the bypass function without affecting the existing system coverage. 
MCPA can be control and monitor locally and remotely through control software. MCPA also has got an external alarm option to integrate with the system alarms which can be monitor from user GUI. 
MCPA are available in tower top and tower bottom model based on the application, output power, number of technologies and number of sectors.
