2110-2170 MHz Operation Manual G3L-2100-30-B (DC) / G3L-2100-30-C (AC) Wideband Multi-Carrier Power Amplifier Operation Manual 2110 MHz – 2170 MHz 044-05133 Rev. A March 2003

G3L-2100-30-B/G3L-2100-30-C Operation Manual Section 1 General Description 1-1 Introduction This manual contains information and procedures for the operation of the model G3L-2100-30-B and G3L-2100-30-C Wideband (WCDMA) Multi-Carrier Power Amplifier (MCPA). The manual is organized into the following sections and appendix. Section 1 General DescriptionSection 2 OperationAppendix A Specifications1-2 General Description The amplifiers are wideband, linear, feed-forward power amplifiers (WPAs) that operate in the 60 MHz frequency bandwidth from 2110 to 2170 MHz with an instantaneous bandwidth of 20 MHz. The amplifier provides linear amplification for single or multi-carrier WCDMA signals. The amplifi-ers communicate with the base station via a TLCI control interface bus; passing alarm and meas-urement information to the base station and receiving control information from the base station. 1-3 Hardware Interface There are three groups of interface connections located on the amplifier chassis. These are RF, power, and control interface (TLCI bus) as described in the paragraphs that follow. 1-3.1 RF The RF interface is located on the power amplifier front panel consists of the RF-In (TX-In) and RF-Out (TX-Out) connectors as shown in Figure 1-1. 1-3.2 Power Supply Power supply voltages (-48 VDC or 230 VAC) from the base station subrack are connected to the amplifier via connector X3, pins A – D located on the power amplifier rear panel as shown in fig-ure 1-1. Table 1-1 lists the voltages and descriptions for each pin.

G3L-2100-30-B/G3L-2100-30-C Operation Manual 1-3.3 TLCI Bus Communications The purpose of the TCLI bus is to provide a communications interface between the power ampli-fier and base station. The bus is connected from the base station subrack to the X3 connector located on the power amplifier rear panel as shown in figure 1-1. Table 1-2 lists the signal names and descriptions for each pin of the 24-pin connector.

G3L-2100-30-B/G3L-2100-30-C Operation Manual 1-4 Alarms The WPA generates the following alarms and communicates then to the base station via the TLIC bus: • VSWR • Gain • Temperature • Over-Drive • Power Supply • Linearization The base station is able to query the current alarm status from the WPA. Fault status is cleared at unit reset which means that any alarm detected after reset is reported to the base station. The alarm status always represents existing conditions. 1-4.1 VSWR The WPA supervises the output (load) VSWR and gives the alarm based on the following limits as listed in table 1-3. Table 1-3 VSWR Alarm Limits VSWR Alarm Status Limits VSWR alarm ON VSWR at the output>8.5:1 @ phase 0-360º VSWR alarm OFF VSWR at the output<3.0:1 or when the VSWR alarm is dis-abled @ phase 0-360º 1-4.2 Gain The WPA supervises the gain of the unit and gives the gain alarm according to the limits listed in table 1-4. Table 1-4 Gain Alarm Limits Gain Alarm Status Limits Gain alarm ON Gain deviates more than ±1.5 dB from specified nominal gain or if the carrier cancellation loop is out of lock, the gain alarm is activated Gain alarm OFF Gain is within the specified range or disabled 1-4.3 Temperature The WPA monitors the internal temperature. The measured temperature must represent the base plate temperature of the main power amplifier. The alarm is given according to the limits listed in table 1-5.  Copyright Powerwave Technologies, Inc., March 2003. All rights reserved 044-05133 Rev. A 1-3 March 2003

This alarm causes an automatic WPA shutdown. 1-4.6 Linearization In case of poor output signal, the linearization causes an automatic WPA shutdown. 1-5 Status Indicator The status indicator LED is located on the WPA front panel as shown in figure 1-1. The LED has tri-color capability: red, yellow, and green. The LED’s blinking frequency is 0.5 – 1 Hz with a duty cycle of 45 – 55%. The LED indicates the status of the WPA as listed in table 1-6.

G3L-2100-30-B/G3L-2100-30-C Operation Manual Section 2 Operation 2-1 Introduction This section contains operating instructions for the G3L-2100-30-B or G3L-2100-30-C wideband power amplifier (WPA). 2-2 Initial Start-Up and Operating Procedures The manual main power supply ON/OFF switch is located on the WPA front panel (refer to figure 1-1 and paragraph 1-5 for status indicator conditions). Turn on the WPA as described in the steps that follow. CAUTION Before applying power, make sure that the input and output of the system is properly terminated at 50 ohms. Do not operate the system without a load attached. Refer to appendix A for input power requirements. Excessive input power may damage the amplifier. WARNING Never remove or install coaxial cables on either the subrack input or output port when the power amplifier is turned on. Operating the power amplifier while disconnecting and connecting RF cables may damage the equipment and/or cause personal injury. 1. Verify that all input and output RF cables are properly connected. Do not apply an RF signal to the WPA. 2. Turn on the main manual power supply switch (1=ON, 0=OFF). The WPA will self-test and initialize (<15 sec), then establish communication with the base station via the TLCI bus. When completed, the WPA notifies the base station that it is ready to be taken into opera-tion. The WPA then remains in a standby state until commanded by the base station. The command received from the base station includes the operating band and based on that band, the pilot frequency sets to 10 MHz lower than the lowest carrier in the operating band. NOTE When the WPA is switched on in temperature conditions below the minimum operat-ing temperature (-10ºC), self-heating is performed until an acceptable operating tem-perature exists. NOTE The main manual power supply switch is also used to reset the WPA by manually set-ting the switch to OFF then back to ON.  Copyright Powerwave Technologies, Inc., March 2003.
