Transceiver Module (Front View) The transceiver generates the station reference, which typically needs to be locked on to one of many possible external sources. The external source can be either the site controller TDM clocks or the external reference operating at 5 or 10 MHz. An internal frequency reference operating at 10 MHz is available in an optional transceiver option card. The transceiver SPI bus allows communication with its receiver and exciter circuitry, as well as the power supply and power amplifier modules. There are two or three circuit boards in the transceiver: • Transceiver Control Board: Performs the control management, digital signal processing, and transmit and receive data formatting for the base radio. • Transceiver RF Board: Contains DC power conversion/regulation and performs receiver and exciter functions. • Transceiver Option Card: An optional board that attaches to the control board. Provides an internal 10 MHz frequency reference. For conventional base radio/receiver operation it also provides the analog interfaces and wildcard I/Os. The transceiver option card requires an internal frequency reference oscillator alignment at different intervals that is mandated by its category and frequency band. See Base Radio Service Help > Service Screens > Alignment Screens in the CSS Online Help for the alignment procedures and mandated intervals. The transceiver option card is available in two categories: • OCXO (Oven Controlled Crystal Oscillator) – operates at 0.1 ppm which is inclusive to temperature and aging. The OCXO Transceiver Option Card is available in 700/800 MHz, UHF R1/R2, and VHF frequency bands. • TCXO (Temperature Compensated Crystal Oscillator) – operates at 1.5 ppm, of which 0.5 ppm is allocated to temperature and 1.0 ppm is allocated to aging. Reference precision with the TCXO is traded for lower power consumption. The TCXO mandates shorter maintenance intervals. The TCXO transceiver option card is available in UHF R1/R2 frequency bands. The TXCO is only available for non-simulcast conventional systems. Transceiver Control Board The main operating software for the base radio is loaded in the transceiver (XCVR) control section. As the main manager for the base radio, the XCVR control board provides operational control over the other station modules. It handles three types of information flow, in the following ways: • Serves as a gateway between the network and RF functionality, by distributing the RF payload to and from the network. • Supports operational and diagnostic functions with digital control data (for example: site information, channel assignments, and identification numbers for call processing). • Ensures the flow of other network management configuration information. EXHIBIT D1-6 APPLICANT: MOTOROLA User / Operational Manual EQUIPMENT TYPE: ABZ89FC3790B Functional Description / Operation of Modules (Draft) The following figure shows the information flow through the transceiver control and RF sections for trunked and conventional operation. Transceiver Control Board Information Flow Transceiver RF Board In addition to DC power conversion/regulation, the XCVR RF board provides circuitry for the following exciter and receiver functions. Exciter The exciter on the XCVR RF board provides the transmitter functions for the base radio. The exciter circuitry generates a low-level, modulated RF signal that passes to the power amplifier. It supports various modulation types as well as bandwidths up to 25 kHz, through software programming. The exciter also provides a controlled output power level to the power amplifier. Receiver The receiver provides either single receiver input or dual (HPD or TDMA) receiver inputs for dual diversity. The receiver also provides enhanced diagnostic capabilities using an on board noise source generator. It includes a wide tuning range (electronic varactor-tuned) preselector. The preselector is electronically tuned to the desired receive frequency anywhere between 792–825 MHz, UHF R1 380–435 MHz, UHF R2 435–524 MHz, or VHF 136–174 MHz. Transceiver External Interfaces The transceiver external interfaces include seven external ports, a switch and LEDs. If a transceiver option card is part of the transceiver, there are four additional external ports. See 3.4.7 Connections – Front, page 3-28 for the port connections. See 10.1 LEDs, page 10-1 for information on the LEDs. Transceiver Switch There is one multifunction Reset switch on the front of the transceiver module, accessible through the drop-down door to the left of the fans. The Reset switch has two functions: User Action Press switch for less than 1 second Press switch for more than 3 seconds Result Service Mode (LED3 lights amber) Transceiver Control Module Reset Transceiver Reset Switch (viewable through drop-down door) EXHIBIT D1-6 APPLICANT: MOTOROLA User / Operational Manual EQUIPMENT TYPE: ABZ89FC3790B Functional Description / Operation of Modules (Draft) Transceiver Option Card Intercom Button There is one intercom button on the front of the transceiver option card, accessible behind the fan module. Pressing the intercom button toggles the intercom function between the ON and OFF states Transceiver Option Card Intercom Button (behind fan module) Transceiver Ports (Rear) The transceiver interconnects to the backplane using a120-pin HVDML digital connector and 8-pack RF connector, as shown in the figure. These connections handle multiple signals including power supply communications, power amplifier communications, fan interface, and peripheral interface. The digital connection receives alarm data and the site controllers' TDM signals, which are used to pass reference and control data to the base radio. Transceiver Module (Backplane Connections) • Single Receiver Input: An RJ-45 Ethernet port on the base radio backplane is cabled to a site LAN switch for this channel. The backplane also provides an RF connection to the transceiver for receive (Rx) path A. • Dual Receiver Input: RJ-45Ethernet ports on the base radio backplane are cabled to corresponding ports on the site controller backplanes (HPD). The backplane also provides RF connections to the transceiver for receive (Rx) paths A and B (HPD and TDMA). EXHIBIT D1-6 APPLICANT: MOTOROLA User / Operational Manual EQUIPMENT TYPE: ABZ89FC3790B Functional Description / Operation of Modules (Draft) Function of the Power Amplifier Module Note: The PA module is not applicable in a GPW 8000 Receiver. The power amplifier (PA) is a forced convection-cooled RF power amplifier. It accepts a low-level modulated RF signal from the transceiver module, and amplifies it for transmission through the site transmit antenna. Also, to complete the Cartesian correction loop (linearization method), it provides a low level RF feedback signal to the transceiver module to achieve the required transmitter linearity. Transmit power output can be set using Configuration/Service Software (CSS). See 4.4.10 Configuring Tx Power Values and Battery Type, page 4-32. The power amplifier also performs functions related to the fan module, including reporting of the fan module status and supplying power to the fan power bus. The power amplifier is comprised of six internal modules: • • • • • • Core Board Converter Board Driver Amplifier Board Final Amplifier Board Distribution Board Output Circuitry Power Amplifier Module EXHIBIT D1-6 APPLICANT: MOTOROLA User / Operational Manual EQUIPMENT TYPE: ABZ89FC3790B Functional Description / Operation of Modules (Draft) Power Amplifier Input / Output Connections There are three electrical connection assemblies on the power amplifier: • RF output (front QN "quick-N" connector) on front of power amplifier module. This is cabled to the N-type female bulkhead connection at the rear of the base radio housing • DC power supply/control signal (backplane connection) • RF input/feedback (backplane connection) Power Amplifier (Backplane Connections) Function of the Fan Module The fan module provides intermittent forced air cooling for the power amplifier and transceiver modules. The fans are controlled by a thermostat in the modules behind the fan module. The fan module houses two 119 mm axial fans which deliver a total of approximately 160 cubic feet per minute of airflow. Nominal fan speed is 4100 revolutions per minute. Each fan has a built-in speed sensor which turns on the red Fan Alarm LED if the fan speed for either fan falls below 30% of the rated speed. If the fan module is used for the Power Efficiency Package, the following must be configured in the CSS in order to take full advantage of the Power Efficiency Package: • Optional fan holdover time (length of time the base radio/receiver fan stays ON after transmission). • Disabling one of the fans within the fan module. See 9.3.1 How To Replace the Fan Assembly, page 9-11 for instructions on how to disable one of the fans. • Configuring the base radios Tx Power Out in the CSS should be limited to 50 W. The fan module connects to the base radio backplane through a 4pin port on the front of the base radio chassis. The power supply module has its own fan which provides independent airflow. Fan Module EXHIBIT D1-6 APPLICANT: MOTOROLA User / Operational Manual EQUIPMENT TYPE: ABZ89FC3790B Functional Description / Operation of Modules (Draft) Function of the Power Supply Module The power supply, with front-to-rear air flow, operates from either an AC or DC input and provides the DC operating voltage for the base radio. However, the power supply prioritizes an AC source (if present) over that of a DC source. If the power supply module is used for the Power Efficiency Package, the power supply must be used in DC mode in order to obtain the 35 W standby power consumption performance. When operating from an AC source (90 to 264 VAC, 47-63 Hz), the supply generates two DC output voltages of 29 V with respect to output ground. The power supply automatically adjusts to AC input ranges and supplies a steady output. In AC mode, the power supply provides a separate battery charger which can be used to maintain the charge on a 48 VDC nominal system, positive or negative ground, if installed. The supply generates two DC output voltages of 29 V with reference to output ground, when operating from a DC source (43.2 VDC to 60VDC maximum, positive or negative ground. This voltage limit includes consideration of the battery charging "float voltage" associated with the intended supply system, regardless of the marked power rating of the equipment. The battery charger is not usable when operating from a DC input power source. This DC source must be located in the same building as the base radio / repeater, and it must meet the requirements of a SELV circuit. The power supply contains several switching-type power supply circuits as follows: • • • Power factor correction circuitry Battery charging circuitry Diagnostics and monitoring circuitry The power supply controls its own continuously running fan, changing its speed to fast or slow as needed. GTR 8000 Base Radio: If the power supply module is used for the Power Efficiency Package, the power supply fan does not run below a 40 °C air inlet temperature in DC mode with the transmitter in a de-keyed state. GPW 8000 Receiver: If the power supply module is used for the Power Efficiency Package, the power supply fan does not run below a 40 °C air inlet temperature. Power Supply Module EXHIBIT D1-6
