Fixed Attenuators - High Power

We are the world leader in fixed attenuators from DC through Q band. Fixed attenuators are available in 0.1 to 400 W versions, covering DC to 50 GHz applications and offered in 0 to 30dB values. Our attenuators are available in several package styles.

Hi-Rel Components

We offer a line of fixed attenuators in a high-reliability S-level common platform for space, military, and aerospace designs. The standard parts eliminate the need for costly and time-consuming drawings and specifications meeting the specification and testing requirements of MIL-PRF-55342. 

Signal Distribution

Smiths Interconnect offers a wide array of products to support signal distribution applications up to 20 GHz. The HybriX® 3 dB Hybrid Couplers are made for applications which require high isolation and low insertion loss. They are surface mountable and packaged in tape and reels. HybriX® Hybrid Couplers have a small footprint, low profile, and are RoHS compliant.

RF Filters and Diplexers

Series of discrete lumped element filters and diplexers with standard “off the shelf” packaging utilizing the same internal components, circuit topologies and transfer functions found in Lorch filter products manufactured for military and space applications. Standard units are an ideal choice when hermetic sealed packages are not a requirement and when lower cost and quick delivery are essential.

MW Couplers Combiners and Splitters

Smiths Interconnect supplies waveguide couplers, combiners and splitters for a variety of space, defense and air defense radar applications. These devices are designed to complement our waveguide isolators and terminations.

Distribution Systems

Smiths Interconnect's Frequency and Time Code Signal Distribution Systems are specifically designed for a wide variety of signal distribution applications including sine wave, time code, and digital signals.

GPS Clocks

Smiths Interconnect's series of GPS disciplined clocks are high performance time and frequency references for applications requiring upmost system accuracy.

Positioners/Controllers - Capabilities

Smiths Interconnect's portfolio of positioners and controllers featuring TECOM technology provide proven turn-key solutions for rugged environments. Selected and deployed by hundreds of domestic and international defense, government and commercial customers, Smiths core capability in positioners not only supports mission-critical programs, but brings front-line visibility to tactical command centers.

Broadband Dual Polarized Log Periodic Antennas

These antennas featuring TECOM technology set the industry standard with an average gain of 7.5 dBi and are ideally suited for direction finding and surveillance applications. Each antenna has two independent planar, log periodic structures positioned at quadrature on a common axis, each having its own feed system. This series of antennas is available in several different models that cover a spectral range of 20 MHz to 26.5 GHz.

Planar Cavity-Backed Spiral Antennas

The planar cavity-backed spirals antennas featuring TECOM technology are circularly polarized, either RHCP or LHCP and have excellent repeatability across frequently and amplitude. These antennas are offered in several configuration to meet your specific system needs in the 1.0 - 18.0 GHz spectrum.
