Attenuators, Terminations & Resistors

Spectrum Control is a solution-minded, performance-driven, customer-focused global supplier of a broad portfolio of RF passive components. We have been delivering quality and innovation for decades with products from our well-known Weinschel and Inmet brands. We offer standard and custom solutions for SATCOM, MILCOM, defense, wireless communications infrastructure, DAS integrators, test & measurement, and more.

COAXIAL SOLUTIONS We offer a full line of standard passive coaxial products and custom-engineered solutions to satisfy market needs for precision and high reliability parts. Products include fixed attenuators, terminations, gain equalizers, bias tees, DC blocks, connectors, and high-reliability attenuators.

SMT SOLUTIONS We design and manufacture a broad range of resistive devices for board-level applications using thin- and thick-film technology. These Powerfilm™ brand components are available in chip, leaded, or flange-mount packages and are enhanced to provide reliable performance in a wide range of frequencies.
