FCC ID:E675JS0067, AN03T2947 Hello Mike, Question #1: Please provide justification for requesting internal photos as confidential document. Answer: <Powerwave Comments> We would like to proceed with requesting confidentiality for the internal photos. I have highlighted in the document you provided the section I believe applies. In four of the attached photos (photos with single model nos.) we are using a process that is not known to the general public/industry. We prefer not to make this publicly available. We feel our product falls into the category stated below. It is sold to only one customer and is serviceable by Powerwave or a licensee. It is definitely not accessible by the general public. "Another example is when a non-consumer device is not accessible by the general public, such as a device mounted on the top of a large tower (or in a fenced enclosure) that is only serviceable by the licensee or his designated technicians." Thank you! Helen

NTUM30DA Installation & Service Manual Section 4 Principles of Operation 4-1 Introduction This section contains a functional description of the multichannel power amplifier (MCPA). 4-2 RF Input Signal The maximum input power should not exceed the limits specified in table 1-1. 4-3 RF Output Load The load impedance should be as good as possible (1.5:1 or better) in the working band for good power transfer to the load. 4-4 Amplifier Functional Description The NTUM30DA amplifier (figures 1-1 and 4-1) is a linear, MCPA that operates in the 60 MHz frequency band from 1930 MHz to 1990 MHz with an instantaneous bandwidth of 20 MHz. The operating band is determined by the operating frequency selection(s) of the base station (refer to table 1-1). The amplifier produces 45 watts of output power when operated in mode 1 or 30 watts of output power when operated in mode 2. Each amplifier is a self-contained module and is func- tionally independent of any other amplifier module(s) in the system. Each amplifier module has an alarm board that monitors the amplifier performance. If a failure or fault occurs in an amplifier module, it is transmitted to the host system via an RS-485 interface. The amplifier is compliant to the requirements of FCC rules with respect to spurious emissions (see table 1-1). Constant gain is maintained by continuously comparing active paths with passive references, and correcting for small variations through the RF feedback controls. All gain varia- tions, for example those due to temperature, are reduced to the passive reference variations. The amplifier module is comprised of: An input amplifier 1 st Loop Phase & Gain A driver amplifier A main amplifier A multifunction board 4-4.1 Input Amplifier RF is fed to the input amplifier, which consists of an isolator at the input, bandpass filter, voltage variable attenuators (VVA), and phase shifters for gain control and phase sweeping functions. The circuits in this section of the amplifier are controlled by a microprocessor on the Multifunction board. At its output, the input amplifier splits the signal to the 1 st Loop Phase and Gain circuit, and the carrier cancellation circuit. 4-4.2 1 st Loop Phase & Gain The 1 st Loop Phase & Gain circuit is a predistortion amplifier. The input signal is predistorted such that it linearizes the output of the main amp at the rated output power of the MCPA. It also contains the main loop VVAs and phase shifters. All the predistortion voltages and loop voltages are controlled by a microprocessor.  Copyright Powerwave Technologies, Inc., June 2003. All rights reserved 044-05141 Rev. A 4-1 June 2003 NTUM30DA Installation & Service Manual 4-4.3 Driver Amplifier The driver amplifier consists of two stages of class AB amplification, which provide the approxi- mately 40% of the gain in the 60 MHz frequency band from 1930 MHz to 1990 MHz. 4-4.4 Main Amplifier The main amplifier employs two class AB amplification stages for maximum efficiency. It provides approximately 40% of the gain in the 60 MHz frequency band. The output from the main amplifier is typically higher than the rated output power of the MCPA, to allow for losses associated with the components in the remaining RF path. The RF signals are then applied to a delay line and directional coupler, where the distortion products are cancelled out and the amplifier power per- formance is monitored. 4-4.5 Multifunction Board The multifunction board consists of feed forward loop control and alarm circuits. The MCPA com- municates to the host system through the multifunction board, which gathers the status informa- tion of the amplifier and reports to the host system via the RS-485 interface when instructed. It also protects the MCPA from adverse conditions such as overpower, input overdrive, over- voltage, etc. A microprocessor on the multifunction board also controls two loops in the feed- forward system.

All rights reserved 044-05141 Rev. A 4-2 June 2003 NTUM30DA Installation & Service Manual 4-6 Power Distribution Primary DC power for the amplifier is provided by the host system. The amplifier generates all the required voltages internally from the main source. 4-7 Amplifier Alarms 4-7.1 Minor Alarms When a minor alarm condition occurs, the alarm is latched into a minor alarm condition. The am- plifier alarm state is read by the BTS the next time the amplifier is poled by the BTS. After the alarm status is sent the minor alarm register is cleared, unless the alarm condition still exists. If the amplifier receives a “Enable Command” or “Clear Alarms Command”, all minor alarms will be cleared. If the amplifier is disabled, all minor alarms are also cleared. Minor alarms do not directly affect amplifier functionality.

NTUM30DA Installation & Service Manual Section 3 Operating Instructions 3-1 Introduction This section contains operating instructions for the Multicarrier Cellular Amplifier. 3-2 Initial Start-Up & Operating Procedures There are no operating controls or indicators on the NTUM30DA amplifier module. To perform the initial start-up, proceed as follows: 1. Verify that all input and output cables are properly connected, per section 2. CAUTION Before applying power, make sure that the input and output of the amplifier are prop- erly terminated at 50 ohms. Do not operate the amplifier without a load attached. Re- fer to table 1-1 for input power requirements. Excessive input power may damage the amplifier. NOTE The output coaxial cable between the amplifier and the antenna must be 50 ohm co- axial cable. Use of any other cable will distort the output. 2. Turn on supply that provides -48 Vdc to the amplifier system. 3. Turn the amplifier front panel switch to On. The amplifier will run through built-in-test for a few seconds, and notify the BTS when the loops converge. The base station allows up to 30 seconds for this step to complete. 4. Turn on external exciter/transceiver and apply RF input signals.  Copyright Powerwave Technologies, Inc., June 2003. All rights reserved 044-05141 Rev. A 3-1 June 2003
