C-Band Solid-State Power Amplifiers DPCD, DPCM6450N Using technology developed for ModuMAX™ amplifiers, these outdoor SSPAs feature a modular architecture with field-replaceable RF assemblies and offer an output power of 450 watts across the standard 5.850–6.425 GHz or extended 5.850–6.725 GHz satellite uplink bands. Housed in a weatherproof NEMA 4X enclosure, the amplifiers can be mounted in an antenna hub or outdoors in applications where it is desirable to reduce cable losses by mounting the SSPA close to the antenna. Built for reliable, trouble-free service, the amplifiers incorporate a microprocessor-based monitor and control system. Features
Applications
• Field-replaceable RF assemblies
• Stand-alone SSPA
• 450 W saturated output power
• 1:1 and 1:2 redundant systems
• Microprocessor-based monitor and control
• Commercial, Government, and Military systems
• Serial interface (RS-232/-422/-485)
Options
• Output isolator for high load VSWR protection
• Block upconverter
• 20 dB range digital gain adjustment • RF output sample port • External mute input • Reflected power monitoring
