MW Isolators & Circulators

Wide range of RF/Microwave isolators & circulators are offered in drop-in, coaxial, microstrip/ surface mount, and waveguide configurations from C-band to V-Band. These high performance components are highly compact, ruggedized and provide superior magnetic shielding. Contact our product experts to discuss your specific system requirements and custom configurations to meet your needs. 

Diamond RF Resistives®

The highest power to size ratio resistive products utilizing CVD Diamond, the best thermal conductor available. Diamond by EMC Technology brand, is the best thermal conductor on earth.

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. 

Thermopad®

Thermopad® products are a totally passive, easy to implement solution for gain compensation designed specifically for demanding high reliability applications.

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.

RF Tunable Filters

Tunable filter products are designed to provide high performance in a single package. While typically used in test and measurement applications, these products can also be ruggedized for mobile and remote applications.

Cavity Filters

Cavity filter designs are available in the frequency range of 30 MHz to 51 GHz and with bandwidth options from less than 0.5% to over 66%. Cavity filters offer the user very low insertion loss, steep skirt selectivity, and narrower bandwidths than discrete component filters.

Discrete Filters

Miniature discrete component filters are designed to give optimal performance where small size is critical. Electrical and mechanical requirements for each design are computergenerated, taking into consideration realizable “Q” and environmental conditions, then analyzed using our unique software, thereby reducing the amount of trial and error alignment.

Ceramic Filters

Ceramic Filters are manufactured in two basic styles for both commercial and military applications. The high volume, cost effective units in open frame, non-hermetic packages are most often used in commercial applications. The lower volume, custom designed hermetic packages find wide usages in military applications. Both styles are available in various mounting configurations. In both instances the same high “Q” coaxial resonators are used which yield low insertion loss and excellent stability over temperature. A low ripple Chebyshev transfer function is standard with bandpass filters, notch filters and diplexer available
