Booster Amplifier Subrack System Integration Manual 044-05078 Rev. A 4-1 November 2000  Section 4. Principles of Operation 4-1 Introduction This section contains a functional description of Powerwave Technologies Inc.’s, Booster Amplifier Subrack (BAS) system. Refer to Figure 4-1 for the system’s functional block diagram. 4-2 RF Input Signal The maximum input power for all carrier frequencies to the system should not exceed the limits specified in Section 1, Table 1-2. 4-3 RF Output Load The load impedance should be as good as possible (VSWR of 1.5:1 or better) in the working band for good power transfer to the load. If the amplifier is operated into a filter, it will maintain its dis- tortion characteristics outside the signal band even if the VSWR is infinite, provided the reflected power does not exceed one Watt. A parasitic signal of less than one-Watt incident on the output will not cause distortion at a higher level than the normal forward distortion (i.e. –65 dBc).

Additionally, the BAS houses a two-way power splitter/combiner and a distribution printed circuit board (PCB). Refer to Appendix A for pinout locations. The RF IN, RF OUT, +27 Vdc and the ALARM summary connector, interface with the host system via front panel cabling. The RF input signal is split equally and applied to the plug-in amplifiers. The output from each am- plifier is an amplified composite signal of approximately 60 Watts before combiner losses. All phase and gain corrections are performed on the signal(s) in the individual amplifier. The amplifier Booster Amplifier Subrack System Integration Manual 044-05078 Rev. A 4-2 November 2000  outputs are fed to a power combiner and combined to form a composite RF output of up to 91 Watts after combiner losses. Refer to Figure 4-1 for the System Functional Block Diagram. The distribution printed circuit board (PCB) assembly is used to distribute power to the BAS sys- tem’s internal components. The PCB circuit is a DC/DC converter designed to convert the +27 Vdc input to +12 Vdc and +15 Vdc. Refer to Appendix B for pinout location. 4-5 Multi-Carrier Power Amplifier (MCPA) Functional Description The MCPA is a linear, feed-forward multi-carrier power amplifier that operates in the 5 MHz fre- quency band from 869 MHz to 894 MHz at an output power 60 Watts. Each amplifier is a self- contained module and is functionally independent of the other MCPA in the system. The amplifiers are designed for parallel operation to achieve high peak power output (refer to Table 1-2 for MPCA power specifications). Each MCPA has an alarm board that monitors the amplifier per- formance. If a failure or fault occurs in an MCPA, it is transmitted to the host system via the D- subminiature 21WA4 connector at the rear of the module. A warning light (LED), which is routed from the amplifier via the J7 connector on the PCB to the front panel of the BAS, will illuminate. The indicator LEDs are identified as Alarm 1 and Alarm 2 which corresponds to their respective amplifier.. The amplifier is compliant to the requirements of FCC Part 22 with respect to spurious emissions. Constant gain is maintained by continuously comparing active paths with passive references, and correcting for small variations through the RF feedback controls. All gain variations, for example those due to temperature, are reduced to the passive reference variations. The amplifier is com- prised of: A preamp A driver amplifier A main amplifier An error and pre-error amplifier Alarm monitoring and control Pre Amp Pre Main Main Amp Error Amp Delay Feed Forward Loop control 2nd Loop Phase & Gain 1st Loop Phase & Gain Delay Alarms & Display +15 +5 -5 Power Supply -30dB -10dB -40dB RF Out RFL PWR FWD PWR Front Panel Smart Rack +27VDC Figure 4-2 Multi-Carrier Power Amplifier Functional Block Diagram Booster Amplifier Subrack System Integration Manual 044-05078 Rev. A 4-3 November 2000  4-5.1 Pre-driver Amplifier The input of the amplifier uses two stages of class AB amplification which provide approximately 13.5 dB of gain in the 5 MHz frequency band from 869 MHz to 894 MHz. The amplifier operates on +27 Vdc. 4-5.2 Three-Stage Driver Amplifier The input of the amplifier uses three stages of class AB amplification which provide approximately 32 dB of gain in the 5 MHz frequency band from 869 MHz to 894 MHz. The amplifier operates on +27 Vdc, and a bias voltage of +5 Vdc. The logic controls the +5 Vdc bias voltage that shuts down the amplifier. 4-5.3 Main Amplifier The signal provides approximately 11 dB of gain in the 869 to 894 MHz frequency band. The out- put from the main amplifier is typically 60 Watts. The main amplifier operates on +27 Vdc, and a bias voltage of +5 Vdc. The alarm logic controls the +5 Vdc bias voltage that shuts down the am- plifier. The main amplifier employs class AB amplification for maximum efficiency. The error amplifier and feed forward loops are used to correct signal non linearities introduced by the class AB main am- plifier. The error amplifier operates in class A mode. The RF input signals are amplified by a pre- amp and coupled to an attenuator and phase shifter in the first feed-forward loop. The main signal is phase shifted by 180 degrees and amplified in the premain amplifier. The output from the pre- main amplifier is fed to the class AB main amplifier. The signal output from the main amplifier is sampled using a coupler, and the sample signal is combined with the main input…

Equivalent test equipment may be substituted for any item, keeping in mind that a thermistor type power meter is required. NOTE All RF test equipment required must be calibrated to 0.05 dB resolution. Any deviation from the nominal attenuation must be accounted for and factored into all output readings. Table 5-2.

Also verify system performance after any amplifier module is replaced in the field. The test equipment required to perform the testing is listed in Table 5-2, and the test setup is shown in Figure 5-1. NOTE The frequencies used in this test are typical for an amplifier with a 5 MHz band from 869 MHz to 894 MHz. Select evenly spaced F1, F2, F3, and F4 frequencies that cover the instantaneous bandwidth of your system. 5-2.1 Amplifier Performance Test To perform this test, proceed as follows: Connect test equipment as shown in Figure 5-1. WARNING Do not apply any RF signals at this time. 5-2.1.1 Amplifier Spurious Emissions Test: With the RF input signal to the amplifier set to be as shown in Figure 5-1, use the spectrum ana- lyzer to measure the spurious emissions performance. Record test data in Table 5-3. Verify that it is within the specifications shown in Table 1-2. Switch tested amplifier to OFF. Booster Amplifier Subrack System Integration Manual 044-05078 Rev. A5-2November 2000  5-2.1.2 Gain Test: 1. Disconnect spectrum analyzer from test setup, and connect the network analyzer. 2. Set network analyzer as follows: A. Power output to -13 dBm. B. Frequency start to 869 MHz. C. Frequency stop to 894 MHz. D. Normalize the network analyzer for gain and return loss. 3. Check the amplifier gain across the band from 869 MHz to 894 MHz. Gain should be as specified in Table 1-2. Record test data in Table 5-3. 5-2.1.3 Input Return Loss: Read and record the S 11 return loss measurement on network analyzer.

A5-4November 2000  5-3 Field Replacement of the Module The GL3-900-60 multi-carrier power amplifier module can be replaced in the field on site by a quali- fied technician with experience maintaining RF power amplifiers and similar equipment: To replace a power amplifier module, proceed as follows: 1. Set on/off switch on the front panel of the amplifier module to OFF (down). 2. Loosen two thumbscrews that secure amplifier module to subrack. CAUTION When removing the amplifier from the subrack, it is very important to support the amplifier such that the rear of the module does not suddenly drop when the guide rail disengages from the track. A drop such as this could damage the rear 21WA4 multipin connector. 3. With steady even pressure, use handle on front of amplifier to pull module out of subrack. 4. Install replacement in reverse order of steps 1 through 3 above.
