Ku-Band Solid-State Power Amplifiers
DPKM, DPKO14200N
Using technology developed for ModuMAX™ amplifiers, these outdoor SSPAs feature a modular architecture with field-replaceable
RF assemblies and offer an output power of 200 watts across the standard 14.00–14.50 GHz or extended 13.75–14.50 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
