Amplifier System Accessories

KIT-EMPOWER1KW is comprised of several accessories required to put the 1 KW family of amplifiers from Empower RF into service. The 0G cables from Gore provide durable, repeatable, reliable performance. The high-power TRU-500 cables from TRU are required to handle the 1 KW of CW power provided at 1,000 MHz. The broadband, high-power directional coupler from IPP is ideal for power monitoring at the output of the amplifier. Each of the components included in the kit are also separately available for customers requiring a different configuration.
