DOCUMENT NO. 217132-001MA PAGE 5 2.0 System Overview 2.1 General Description The 24W Remote Node MCPA is composed of an MCPA (Multi-Carrier Power Amplifier), a passive TX Filter, an AC Power Supply, two fans and a DCDC Converter board. It’s main feature is to amplify one or more RF carriers in a range of 27.5 to 43.0dB. Modules Description The Power Supply converts the 110VAC to +28VDC to power up the MCPA and the DCDC Converter module. The DCDC Converter module provides +24VDC to the fans and a +5VDC for the Controller module (not included in the Remote Node MCPA as shipped to the customer). The MCPA’s function is to amplify the input signal by 48dB. The MCPA is a linearized feed-forward amplifier with a pilot tone. There are two sections to the amplifier, the main amplifier and the error amplifier. The error amplifier is there to cancel part of the intermodulation products that are generated in the main amplifier whose function is to amplify the input signal to 24Watts. The pilot tone is used to monitor and cancel these intermodulation products. The cancellation is adaptive, meaning that a sample of the pilot tone is fed back to the main and error amplifier to adjust their phase and amplitude to maintain good cancellation of the intermodulation products over time and temperature. The MCPA gain is controlled using an integrated digital attenuator, which has a range of 0 to 15.5dB. The MCPA also has over power and over temperature protection. The TX Band Pass Filter is used to remove undesired the out of band spurious. 2.1.1 Abbreviations and Explanations Table 1 - Abbreviations Table Abbreviation Explanation BTS Base Transceiver Station DAS Distributed Antenna System MCPA Multi-Carrier Power Amplifier MHz Megahertz mm millimeter RN Remote Node 2.2 Preparing for Installation Before attempting to install or use the 24W Remote Node MCPA, we recommend that you first familiarize yourself by reading through this documentation package. Understanding the system operation will reduce the possibility of incorrect installation, thereby causing damage or injury to yourself or others. The MCPA must be installed in accordance with the conditions and recommendations contained in the following sections. The HPA must be installed in a restricted location area accessible only to authorized personnel.

DOCUMENT NO. 217132-001MA PAGE 6 2.3 Safety Precautions Carelessness or mishandling of the 24W Remote Node MCPA may damage the equipment causing serious injury to yourself or others. All installation activity must be carried out in compliance with the safety instructions supplied with the BTS and with local standard authority warnings and precautions.. Please adhere to the following: WARNING!! This equipment is designed for use with high power radio frequency (RF) radiating systems. Personnel must take precautions to minimize exposure to the RF fields by making sure that the output port is terminated(connected to an antenna OR attached to a >40W RF load) at all time when the amplifier is running. It is also highly recommended that the input port is terminated to protect the devices from accidental overdrive (oscillations), which could damage the amplifier. WARNING!! The equipment is designed for use with equipment that generates high voltages. Proper precautions must be taken when working with this equipment. CAUTION! To prevent damage to static sensitive devices, ESD (electrostatic discharge) precautions must be observed when handling or installing the modules or subassemblies of the 24W Remote Node MCPA. Do not tamper with, or attempt to reconfigure, the cords or plugs supplied with the modules of the 24W Remote Node MCPA, as this can: ♦ result in personal injury ♦ void the warranty ♦ cause damage to the units or related equipment 2.4 Warranty Information Mitec Telecom Inc. will warranty each product that it manufactures to be free from defects in materials and workmanship for a period of twelve (12) months.

DOCUMENT NO. 217132-001MA PAGE 15 4.0 System Verification Test The following test sequence should be carried out to make a quick functional test or verification of the unit. It is not intended to cover all system capabilities, but rather to confirm that the MCPA is ‘healthy’ and can deliver the expected RF power. WARNING!! The equipment is shipped without a controller (provided and integrated by the customer). In order to test the unit, a “ jumper” has been soldered to short pin 1 and 15 of the MCPA DSUB 15 connector to enable the MCPA at power up. Operator must make sure to connect the RF Output port to an Antenna or a 50W RF Load before applying AC Power to the unit. Operator must make sure the RF input port is not left opened to avoid oscillation. The RF input cable (from the BTS) must be connected or the port terminated with a 50-Ohm adapter. The following picture shows the recommended bench setup for the verification. The Signal Generator could be replaced by the BTS signal and the RF Load by the antenna and its cable. The output power could be measured by reading the dc voltage on pin 9 of the MCPA DSUB connector, but the recommended setup was defined such a way to avoid opening the unit. For that reason an external coupler is required. PWMSigGen 20WMCPACoupler20dB> 30W load20dB padPower HeadMax Input: -3dBmBTSOROR Figure 5 – Recommended Test Setup
