Pico Macom DSU-2P, DSU-4P, DSU-3P, DSU-8P, MS-2D Specifications

Manufactured to high performance standards, TruSpec’s DSU-series 1GHz
professional-grade MATV splitters provide excellent performance at low costs,
rivaling competitors’equivalent models. Applications range from residential to
MDU installations in international and domestic cable distribution systems. Our
advanced printed board circuitry includes special ferrite core material guar­anteeing minimal insertion loss, optimal isolation and return loss to 1GHz
ensuring high-quality signal transfer. DSU series F-port threads are precision
machined, ensuring easy connector installation and removal, and improved
port-to-connector interface.The zinc-alloy cast case and epoxy sealed back
plate provide superior RFI shielding (-70dB) and a full environmental seal.
Each DSU splitter is individually tested at the factory to comply with precise
quality standards.
