Introduction 1.1 Document Scope This document describes the hardware of the model HPA4 UHF High Power Amplifier. Section 1: non-technical overview of the product and its features Section 2: identifies product interfaces (i.e. connectors, power sources, etc.) Section 3: contains installation information Section 4: provides functional description of circuit operation Section 5: maintenance Section 6: identifies the specifications the product is designed to meet Section 7: contains warranty and service information Section 8: contains internal interconnections, schematic diagrams, parts lists, and component location drawings Throughout this document, SMALL CAPITAL LETTERS are used to indicate signal names used on schematics and Italics are used when describing circuitry, methods, or devices which affect regulatory compliance. 1.2 Reference Material 1.2.1 ElectroCom Documents (Attached) NUMBER DOCUMENT NUMBER 502-8800958 PL502-80059 502-80185 502-80073 DESCRIPTION Schematic - High Power Amplifier HPA4 Parts List Hi PWR AMP UHF Interface Locator Drawing Interconnection Diagram HPA4 1.3 Product Description ElectroCom's Model HPA4 UHF Amplifier is designed to amplify the RF output of ElectroCom's DR4B Base Station up to 100 Watts. The HPA4 uses a dual amplifier design to ensure graceful degradation of output power under fault conditions and enhanced reliability. The HPA4 features a three-stage thermal equilibration system, and over-voltage protection prolonging the life of the amplifier. 1.4 Product Features: Model HPA4 High Power Amplifier Features: • Dual Amplifier Design • 3-Stage Thermal Equilibration • Over-Voltage Protection • 12 VDC operation • Compact size, rugged construction J2 RF OUT RF IN J1 J4 J3 CONTROL INTERFACE DC POWER COOLING FAN 2. Interface Description The HPA4 has 2 external RF ports; both are type "N" female coaxial connectors: J1 is the RF input port J2 is the RF output port DC power connection to the HPA4 is accomplished via J3, a 2-conductor, quickdisconnect connector. J4 is a control / alarm cable which carries the amplifier's key signal and high-temp alarm signal. 3. Installation 3.1 Unpacking Carefully inspect the amplifier for any signs of shipping damage. If damage is suspected, file a claim immediately with the carrier and contact your dealer. If possible, keep the original shipping container for shipping the unit back for repair or for verification of damage during shipment. 3.2 Installation Standard considerations such as air flow clearance in the vicinity of the amplifier's mounting location, and ensuring adequate space exists for the routing of RF, DC power, and control cables are of primary importance. RF coaxial, power, and control cables should be neatly routed with service loops to provide for convenient removal for functional testing and / or maintenance purposes. 3.1.1.
