RF Power Amplifiers Introduction This document presents description of the Andrew Corporation 45W UMTS 850MHz MCPA (Multi-Carrier Power Amplifier). The MCPA amplifier is a high power, low distortion RF amplifier intended to provide signal amplification and conditioning. The MCPA amplifier is compatible with the UMTS WCDMA air interfaces operating in U.S. domestic cell sites where FCC compliance is mandatory.
PAGE 3
RF Power Amplifiers The MCPA amplifier has been designed to support a max instantaneous bandwidth of 10 MHz which is equivalent to the 2 carrier UMTS WCDMA signal. The MCPA amplifier has a nominal gain of 46.5dB and is less than 1dB variation over the operating temperatures. The nominal RF input power is 0dBm.

RF Power Amplifiers Control System: The MCPA will work with the customer BTS which control and monitor the MCPA by the specified interface protocol. A microprocessor controller is inside the MCPA to be compatible with the customer interface protocol and assures the MCPA performance meet the specification.

RF Power Amplifiers Installation and Operation Set-Up The MCPA is easy to operate and use. All the require connections is located on the front panel of the MCPA where is easy to access. The MCPA will be installed on slide-in rack first. Make sure the DC power switch is in the OFF position, and then connect the DC power, the communication and the RF input/output cable to the MCPA. After check the all connection is correct and reliable, the last step is to turn on the DC power switch.
