Spectrum Control
Spectrum Control is a leader in the design and manufacture of control products and systems used to condition, regulate and
govern electronic performance. Over the past several years, we have leveraged our core electromagnetic interference (EMI)
filtering expertise to offer our customers a broad line of signal, power, and frequency control products. Our operations are
currently conducted in three reportable segments: signal integrity products; power integrity products and management
systems; and frequency control products. Our Signal Integrity Products Group designs and manufactures a broad range of low
pass EMI filters, surface mount EMI filters, filtered arrays, filtered connectors, gaskets, and specialty ceramic capacitors. Our
Power Integrity Products and Management Systems Group designs and manufactures numerous power integrity products
(power line filters, power entry modules, multisection filters, power terminal blocks, and custom power filter assemblies) and
power management systems (power distribution units, remote power management systems, fuse interface panels, breaker
interface panels, and custom power distribution systems). Our recently developed Frequency Control Products Group designs
and manufactures ceramic resonators and bandpass filters, ceramic patch antennas, duplexers, lumped element filters, cavity
filters, waveguide filters, and related products and systems.
