III. OPTIONS TPL Communication’ UHF high band continuous duty RF Power Amplifiers are available with several options: input, output, frequency ranges and configurations, special logos, etc., when specified at the time of order. We work closely with you, our customer, to develop products that are in complete compliance with your needs and specifications. NOTE: All TPL Standard UHF high band continuous duty RF power amplifiers are factory-tuned to the frequency specified at the time of order.
V. OPERATING PRECAUTIONS CAUTION: This amplifier produces RF voltages that can cause painful and dangerous burns. Use caution! Connect and disconnect all RF connections with the drive power and DC power off. DRIVE POWER: RF power transistors, although quite rugged in most respects, are easily damaged by overdrive. Be careful not to overdrive the amplifier even momentarily (before applying any drive signal please check product specification for details).
VI. INSTALLATION The PA8-1AC amplifiers are designed for mounting in a standard 19-inch rack. When picking a location in the rack, considerations must be given to RF cable lengths as well as cooling. Mount the amplifier away from the sources of heat where dust and other debris are not likely to clog the cooling fan and as close to the antenna as practical. Keep coaxial cable runs short, avoiding sharp bends and pinching. Avoid loose connectors at the ends of the coaxial cables.
VII. WARRANTY TPL COMMUNICATIONS has tested and found this unit to function properly and to operate within the parameters of its stated specifications. TPL COMMUNICATIONS warrants that this product is free from defects in material and workmanship. If found to be defective within two (2) years from the date of purchase, the factory will, at its discretion, either repair or replace the unit at no cost, provided the unit is delivered by the owner to the factory intact.
