Introduction 1.1 Scope This document describes the hardware of the HPA8 High Power Amplifier as follows: Section 1: Overview of the unit and its features. Section 2: Interfaces (e.g. connectors, power sources, etc.). Section 3: Installation procedure. Section 4: Circuit theory. Section 5: Maintenance procedures. Section 6: Specifications. Section 7: Warranty and warranty/non-warranty service information. Section 8: Diagrams and lists. FCC ID: MI7-ECSHPA80TX A2 1.2 Reference Materials 1.2.1 ElectroCom Documents (attached) The following ElectroCom documents are provided as attachments to Section 8: NUMBERDOCUMENT NO.DESCRIPTION 1HPA8Block Diagram 2502-80228Interconnection Diagram 3502-80228Schematic Diagram 4502-80292PWA Parts List FCC ID: MI7-ECSHPA80TX A3 1.3 Product Description The ElectroCom HPA8 High Power Amplifier was designed specifically to operate with the ElectroCom IP8B Base Station Data Transceiver. Basically, the unit amplifies the RF output of the IP8B, providing up to 80 watts of RF power for the antenna system. The HPA8 is intended for base station use only. For enhanced reliability, the HPA8 incorporates a four power amplifier module design which permits “graceful” degradation of output power under fault conditions. This means the unit will continue to operate (albeit at gradually reduced power levels) despite failures in up to three power amplifier modules. The useful life of the HPA8 is extended by a 3-stage thermal “equilibration” scheme. “Equilibration” refers to the act of equalizing the operating temperatures of the four power amplifier modules. By doing so, and by keeping the temperature within reasonable limits, heat stress on the modules is minimized. This results in longer operating life for the modules, and increased overall reliability for the HPA8. The HPA8 is equipped with over-temperature and over-voltage protection. To prevent damage from excessive heat, or from a defective power supply, the cabinet temperature and power supply voltage is monitored at all times. 1.4 Product Features The HPA8 High Power Amplifier features: • 80 watts RF output (typical). • Covers 851-866 MHz • Four power amplifier module design. • Graceful degradation of power under fault conditions. • 3-stage thermal equilibration protection system. • Over-temperature protection. • Over-voltage protection. • 13.8 VDC operation. • Compact size, rugged construction. FCC ID: MI7-ECSHPA80TX A4 2. Interface Description As shown in section 8.3, the HPA8 has the following interface connections: J1 RF input. Typically connects to the IP8B Base Station Data Transceiver. J2 RF output. Typically connects to the antenna system components in the rack. WARNING! Do not remove the harmonic filter, or operate the HPA8 without the filter installed. Excessive harmonic emissions may result. J3 DC power connector. Plugs into a 13.8 volt (nominal), 25 amp (or greater) DC power supply. J4 Control interface connector. The transmit keying input connects to the IP8B Base Station Data Transceiver via an INVADR I/O Interface Board mounted on the rack. The high temperature alarm output may be connected to an alarm monitoring system, or to the ALARM connector on the INVADR I/O Interface Board. 3. Insta…

To whom it may concern, I recently sumitted a Form 731 with an incorrect FCC Id number Confirmation # EA100393 and FCC ID:MI7ECSHPA80TX. The correct ID number should read as follows MI7-ECSHPA80TX. Please change Form 731 so that all the paper work reflects the correct Id number. If you have any questions please contact myself or Bryan Broaddus at ([email protected]). Thank you, Fred Gurule DNB Engineering, Inc. \ [email protected]
