Advanced LDMOS design permits the PA700 to operate with high level digital signals such as 64QAM, DVB-T or 8-VSB DTV. The PA700 can be operated on a stand-alone basis or controlled via SNMP or front panel display when serially connected to a UCD4940. Together, the PA700 and UCD4940 offer a complete solution for up-conversion, down-conversion and high linearity amplification in a rack mount configuration requiring only 4U of rack space*. This advanced, cost effective power amplifier offers high performance and flexibility in a space-efficient design. The unit is state of the art in terms of easy assembly, reliability and performance. The PA700 is factory configured and calibrated for operation at a specific band.  !• 80W typical transmit power with 64QAM or DVB-T modulation • Alarms and automatic protection for RF faults, over-temperature, over-drive, output VSWR, and over-current • Enable/disable via front panel switch or two pole rear connector • Monitor and control via RS232/RS485 • International switching power supply (100 to 240 VAC) "#$%&'()*)+!• Local control via LCD and 4 soft touch push buttons • Remote control and monitoring via RS232/RS485, Terminal or optional SNMP • Automatic level control • 44 MHz input for up-conversion and amplification of IF modulators or Cable Modem Termination Systems

If it appears damaged in any way, notify the carrier, and keep all packing materials for inspection by the carrier’s agent. /%& Note: This unit should be installed by qualified service personnel only. Diagram 2.2 details the input and output connections for the PA700. 1. Carefully identify between the electrical ground of the AC power supply and the station ground that is common to the antenna system, other RF components and the transmitter rack cabinet. Ensure that the PA700 and the CMTS ground points are connected to the station ground and not the electrical ground. 2. If installing the PA700 into an equipment rack, use the 4 mounting holes on the front of each cabinet. It is also important to connect the rear side of the PA700 chassis to the same rack cabinet using a rear support bracket (not supplied). 3. It is suggested that a heavy gauge line cord (No. 10 AWG stranded) with connector be used in most applications for connection to the AC power supply. The AC power connector and station ground stud are located on the rear panel (refer to Diagram 1.4B). 4. Prior to connection, please ensure that the frequency, modulation and BW of the CMTS or CMTS/upconverter are set for the application. PA700 type approval for the US lower 700 MHz band under FCC Part 27 is only valid for the following input frequency and modulation combinations and only when the VCom duplexer is connected between the output and the antenna. Carrier Bandwidth Center Frequency Range Modulation 2 MHz 741-745 MHz QPSK, 16QAM, 64QAM 6 MHz 743 MHz only QPSK, 16QAM, 64QAM 5. Adjust the input level so that the input power to the unit is nominally -7 dBm. 6. Connect both upconverter/CMTS to unit and duplexer/antenna assembly 7. Adjust input level so that output power is +48 to +49 dBm as reported by MSM server or the UCD4940. Opeartion below this level will result in less than optimal performance and operation above this level may violate regulatory emissions requirements. WARNING! Maintain a distance of at least 10mm (3/8 “) between PA700 units when mounting several units in a rack. The rear air outlets should be unobstructed.
