044-05236 Rev A1-1 Chapter 1 Product Description 1.1Introduction This manual contains information and procedures for the installation, operation, and maintenance of the G3L-850-160 Multi-Carrier Power Amplifier (MCPA). 1.2Scope of Manual This manual is intended for use by service technicians familiar with similar types of equipment. It contains service information required for the equipment described and is current as of the printing date. Changes which occur after the printing date may be incorporated by a complete manual revision or alternatively as additions. The manual is organized into the following chapters: 1.3Product Description The MCPA shown in Figure 1-1 is a linear, feed-forward multi-carrier power amplifier that operates in a 25MHz frequency band from 869 MHz to 894 MHz with an instantaneous bandwidth of 25 MHz. The instantaneous bandwidth is the maximum frequency band in which any two or more signals can occupy. The instantaneous bandwidth of the MCPA is set automatically. The MCPA is modular in design and ideally suited for use in GSM, EDGE, CDMA, and W-CDMA base stations. The MCPA provides a gain of 63 dB to provide a 160 watt output. Refer to Figure 1-2 for the MCPA functional block diagram. Refer to Chapter 5 for the MCPA specifications. 1.4Functional Description The MCPA is a self-contained module typically operated in parallel with other identical MCPAs as part of a subrack assembly. The MCPA consists of the following major functions: • Preamplifier • Main and error amplifiers • Feed-forward loop control circuits • Pilot tone generator Chapter 1 - Product Description Chapter 2 - Controls and Indicators Chapter 3 - Installation Chapter 4 - Maintenance Chapter 5 - Specifications Functional DescriptionG3L-850-160 MCPA 1-2044-05236 Rev A • Controller Figure 1-1 MCPA Front and Rear Views Front Rear G3L-850-160 MCPAFunctional Description 044-05236 Rev A1-3 1.4.1 Preamplifier The carrier (RF In) is applied to the input port of the MCPA and fed to the preamplifier stage where it is amplified using two stages of class A mode amplifiers. The output of the preamplifier is split into two paths, one to the main amplifier and one to the error amplifier. 1.4.2 Main and Error Amplifiers The main amplifier provides the balance of gain and power in the 869 MHz to 894 MHz frequency band, using class AB amplification for maximum efficiency. The error amplifier and feed forward loops correct signal non-linearities introduced by the class AB main amplifier. In the error amplifier, which operates in class A mode, the RF signal is coupled to an attenuator and phase shifter in the first feed-forward loop, phase shifted by 180 degrees and then amplified in the premain amplifier. The output from the pre-main amplifier is fed to the class AB main amplifier and then sampled using a coupler. The signal (RF sample) is combined with the main input signal and input to the second feed-forward loop. There, the RF sample is attenuated, phase shifted 180 degrees, and fed to the error amplifier where it is amplified to a level identical to the sample output from the main amplifier. The output from the error amplifier (Error Out) is coupled back and added to the output from the main amplifier, with the control loops continuously making adjustments to cancel out any distortion in the final output signals.

It does this by amplifying the carrier signals and isolating an error signal which is passed to the second loop. The first loop control section phase shifts the main input signals by 180 degrees and constantly monitors the output for correct phase and gain. The primary function of the second loop is to amplify the error signal to cancel out spurious products developed in the main amplifier. The input signal is amplified by a preamplifier and fed to a coupler and delay line. The signal from the coupler is fed to the attenuator and phase shifter in the first loop. The second loop control section obtains a sample of the distortion added to the output signals by the main amplifiers. The signal is phase shifted 180 degrees, then fed to the error amplifier where it is amplified to the same power level as the input sample. The signal is then coupled to the main amplifier output. The final output is monitored by the second loop and adjusted to ensure that the signal distortion and intermodulation distortion on the final output is cancelled out. During routine operation, all normal variations are automatically compensated for by the feed-forward loop control. If large variations occur beyond the adjustment range of the loop control, the controller shuts down the MCPA RF section and a loop fault is reported to the system. 1.4.4 Pilot Tone Generator The pilot tone is an internally generated signal with a predetermined frequency, phase, and amplitude is known. If the pilot signal is suppressed at the amplifier output, then the distortion created by the main amplifier is also suppressed. The pilot tone signal is injected into the first loop and detected at the feedforward output of the second loop. The pilot tone is coupled off of the main amplifier creating a second pilot tone that is attenuated and phase shifted 180 degrees to be used as the reference. The second pilot tone is amplified in the error amplifier and mixed with th…

044-05236 Rev A4-1 Chapter 4 Maintenance 4.1Introduction This chapter contains instructions for periodic maintenance, testing and troubleshooting for the G3L- 850-160 Multi-Carrier Power Amplifier (MCPA). 4.2Periodic Maintenance Periodic maintenance requirements for the MCPA are listed in Table 4-1. 4.3MCPA Performance Tests MCPA Performance tests are only performed at the factory. Refer to the troubleshooting instructions in Section 4.4. 4.4Troubleshooting Perform the instructions in Table 4-2 in the case of an MCPA fault or alarm. 4.5MCPA Removal and Replacement Perform the instructions in Table 4-3 to remove and replace a MCPA. NOTE Check your sales order and equipment warranty before attempting to service or repair unit. Do not break seals on equipment under warranty or the warranty will be null and void. Do not return equipment for warranty or repair service until proper shipping instructions are received from factory. Table 4-1 Recommended Periodic Maintenance TaskIntervalAction Cleaning 3 MonthsInspect for debris especially around front panel vents. Remove dust with a soft cloth/brush or vacuum cleaner Performance testsOptionalPerform testing in accordance with Paragraph 4.3. Table 4-2 Troubleshooting StepAction 1Check for proper DC supply voltage. 2Set the OFF/ON/RESET switch momentarily to RESET (Up) position. 3Contact your field representative or the factory if fault does not clear. Return For Service ProceduresG3L-850-160 MCPA 4-2044-05236 Rev A 4.6Return For Service Procedures When returning products to Powerwave, the following procedures will ensure optimum response. 4.6.1 Obtaining An RMA A Return Material Authorization (RMA) number must be obtained prior to returning equipment and to reduce delays in receiving repair service. Please contact our Repair Department at (714) 466-1000 to obtain this number, or FAX your request to (714) 466-5816. 4.6.2 Repackaging for Shipment To ensure safe shipment of a component, it is recommended that the original packing materials be reused If this is not possible, use suitable shipping cartons and foam inserts to prevent damage in transit. CAUTION: Do not slam the MCPA into the system during installation. Using excessive force can damage the MCPA connector. CAUTION: When removing the MCPA from the system, support the MCPA to prevent the rear of the MCPA from suddenly dropping when the guide rail disengages from the track. Dropping the MCPA can damage the rear multi-pin connector. The MCPA weighs approximately 28.60 lbs. (12.97 kg). Table 4-3 MCPA Removal and Replacement StepAction 1Set MCPA OFF/ON/RESET switch to OFF (down). 2Loosen two quarter-turn fasteners that secure MCPA to the subrack. 3With steady even pressure, use handle on front of the MCPA to pull the MCPA out of the system. 4To replace MCPA, set MCPA OFF/ON/RESET switch to OFF (down). 5Turn quarter-turn fasteners to Unlocked position. 6Insert MCPA into subrack. Turn quarter-turn fasteners to locked position to secure MCPA.
