Dow-Key Microwave is an ISO 9001 certified manufacturer of electromechanical coaxial and waveguide switches, switch matrices, integrated modular assemblies, and related passive components. Dow-Key's product line ranges from single-pole single-throw to single-pole 14-throw switches as well as transfer, in-line and waveguide switches, switch matrices, and integrated modular switch assemblies.Dow-Key Microwave, a leader in the design and fabrication of switching products, has supplied the aerospace, military and communication industry with state-of-the-art products to direct RF energy since 1945. To date, thousands of designs have been created and manufactured at our facility located in Ventura, California, USA. Dow-Key offers switching products to four major markets – Commercial, Military, Avionics and Hi-Rel/Space which includes individual coaxial, waveguide, board mount, and MEMS switches along with custom integrated assemblies and switch matrices.  

K&L Microwave is a leading manufacturer of RF and Microwave Filters used in commercial wireless communications and defense electronics systems. Commercial Products include filters, duplexers and combiners as well as integrated assemblies that combine filters with amplifiers, couplers and other microwave components. K&L supplies Military Customers with multi-function assemblies and a wide assortment of filters using lumped component, cavity, ceramic and suspended substrate topologies. K&L designs and manufactures a full line of RF and Microwave filters, duplexers and sub-assemblies, including ceramic, lumped element, cavity, waveguide and tunable filters. The wireless products group consists of high-performance receive and transmit filters, delay line filters, duplexers and diplexers, combiners, receive multicouplers and wireless system assemblies for base station infrastructure requirements. K&L's Microwave and RF filters are designed to pass specified sets of frequencies while rejecting others and are used in systems such as satellite communications, radar, radio communications, fire control radars, telemetry applications, missile guidance systems, mobile radio base stations and air traffic control and communications.  

Pole/Zero designs and manufacturers RF filters to control this cosite related problem. With it’s full line of digitally tunable RF filters including the Bandpass filters (MicroPole MiniPole, MaxiPole, and PowerPole), Notch filters, and Integrated Cosite Equipment (ICE) Pole Zero can effectively solve most interference issues. For over a decade, Pole/Zero has developed and fielded products to expand the linear dynamic range of communications products from 1.5 MHz to 3 GHz. Success in providing customers with quality products and services has resulted in continued growth since it was founded in 1989.Through constant product, technology, and process development, Pole/Zero continues to expand its roles as the leading supplier of unique, cost-effective solutions to solve difficult RF problems. 

Dielectric Laboratories  supplies microwave and millimeter wave components for optical and wireless communications, military, medical, semiconductor, aerospace and transportation markets. We are the world’s largest supplier of high Q single-layer capacitors, a global leader in high Q multi-layer capacitors, and offer the world’s most comprehensive line of broadband blocks. Our high performance line of cavity resonators, custom filters, equalizers and heat sinks is based on decades of design and ceramics processing know-how.

Novacap  supplies high-end Multilayer Ceramic Capacitor (MLC) products to the aerospace, military, medical, telecommunications, computer and oil exploration markets. We specialize in application specific multilayer ceramic capacitors and capacitor assemblies using a broad range of materials technologies, including industry-leading high temperature components. Our products include surface mount capacitors from the 0402 case size to large, high voltage components (up to 20kV) for Commercial and High Reliability applications. 

Syfer Technology Limited is dedicated to the manufacture of ceramic multilayer components. Our comprehensive product range includes high volume ceramic chip capacitors through to application specific capacitor assemblies and highly complex planar arrays. We also design and manufacture a range of EMI filters including threaded and solder in panel-mounted styles as well as surface mount devices for pcb applications.  

Voltronics Corporation is the world leader for precision multi-turn trimmer capacitors. Our high performance trimmers are capable of operating under severe conditions of voltage, vibration, frequency and temperature. We grow by being open to new ideas which will better suit the needs of our customers. Our "specials" number in the thousands. If you cannot find the perfect part for your circuit, contact us and we'll design it.
