1-1January 2001 General Description Introduction This section contains a functional description of Powerwave Technologies Inc.’s, Booster Amplifier Subrack (BAS) system. Refer to figure 1-1 for the system’s functional block diagram. RF Input Signal The maximum input power for all carrier frequencies to the system should not exceed the limits specified in table 1-1.

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 distor- tion 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). 1-2January 2001 MCR 20930-1-2 MCR 20930-1-2 MCPA MCPA RS-485 Alarm Interface VVA C o m b i n e r GAIN CTRL Splitter Distribution Circuit Board (DC,Fans, Alarms) ISO ISO -25dB Sample DB9 Alarm Alarm Ctrl 2x +27VDC 2x Ground RF Input RF Output GL3-900-50-005 GL3-900-60-005 30 dB Figure 1-1System Block Diagram System Functional Discription Designed as a subrack for installation in a 2-way transceiver paging base station, the BAS system is comprised of a MCR20930-1-2 Booster Amplifier Subrack (BAS) and two G3L-900-50-005 or G3L- 900-60-005 plug-in multi-carrier power amplifiers (MPCAs). 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 (refer to table 1-2 for amplifier output specifications). All phase and gain corrections are performed on the signal(s) in the individual amplifier. The amplifier outputs are fed to a power combiner and combined to form a composite RF output (refer to table 1- 2). Refer to figure 1-2 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. 1-3January 2001 Table 1-2 G3L-900 Series Amplifier’s Electrical Specifications Frequency Range935-940 MHz Channel Spacing12.5 KHz Output Power: GL3-900-60-005+47.8 dBm (60 Watts) nominal, 75 Watts (max.)

(shall incorporate an output isolator) 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 935 MHz to 940 MHz (refer to table 1-2 for amplifier specifications). Each ampli- fier 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 performance. 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 ampli- fier. 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 1-4January 2001 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 PanelSmart Rack +27VDC Figure 1-2 Multi-Carrier Power Amplifier Functional Block Diagram Predrive…
