1.0 GENERAL INFORMATION 1.1 System Overview The MA4061B is a fully agile commercial quality IF upconverter for MMDS and LMDS applications. Advanced design permits full frequency agility over the 2500 to 2686 MHz frequency band while still maintaining a phase noise specification which exceeds the requirement of 64 QAM. The MA4061B is a modular circuit card designed for use with the WaveCom MA4000 Series. The MA4070B is a solid state, fixed gain 12W power amplifier for MMDS applications.

2.0 INSTALLATION 2.1 Unpacking the Unit Carefully remove the equipment from its packing material and set it on a solid surface, such as a table or desk. If it appears damaged in any way, notify the carrier, and keep all packing materials for inspection by the carrier’s agent. 2.2 Operating Environment The MA4001B chassis includes an active cooling fan tray which forces cooling air from the bottom through to the top of the chassis.
2.5 Module Installation/Replacement 1. Power off the chassis using the rear panel AC switch 2. Disconnect the RF cables from the rear of the corresponding module 3. Using a screwdriver, loosen the corresponding front panel captive screws until the module is free to pull forward 4. Insert the replacement module and retighten the front panel captive screws 5. Turn on the AC power switch 6. Configure the output frequency and configure IF/RF levels 7.
