Standard RF & Microwave Semiconductors that Make the Grade
In an effort to address the market pressures of lower cost and reduced lead times, Micross Hi-Rel RF Solutions offers a growing library of proven Standard Products, designed and manufactured following the guidelines and test flows of MIL-PRF & EEE-INST-002 performance specifications. Most of our RF and Microwave surface mount semiconductor components are available as commercial, military, or space grade.
Micross Hi-Rel RF Solutions offers an ever-expanding line of Standard off the shelf products designed specifically for use in harsh environments. A sampling of the products that Micross Hi-Rel RF Solutions offers include:
- Switches: GaAs, PIN, SPST through SP8T available with driver
- Amplifiers: LNAs, Driver Amplifiers, and Power Amplifiers in GaAs or GaN
- Attenuators: VVAs or DSAs with or without driver
- Frequency Conversion: Vector Modulators, Frequency Multipliers
Micross Hi-Rel RF Solutions standard surface mount components and hybrid parts are available for commercial, or purchased to meet the requirements of EEE-INST-002, MIL-PRF-38534, MIL-PRF-38535, all equivalent international documents, or to an SCD. This approach allows Micross to develop a library of standard products from proven die and packages, with all the required documentation already in place. The result is lower total cost solutions with quicker delivery.
Custom RF & Microwave Semiconductors that Meet Your Needs
Micross Hi-Rel RF Solutions continues to support Hi-Rel surface mount semiconductor components designed for specific customer drawings, provide support for obsolescence issues, co-develop products that take commercial die to the next level of protection and reliability, integrate functionality specific to a customers’ need, and develop a part that will provide a differentiator for assembly or system architecture. In addition to catalog parts, Micross is able to offer application-specific semiconductor solutions such as:
- Modification of catalog products
- Creation of a product from the ever-expanding library of proven die and packages
- Creation of a product from available commercial die packaged in proven packages
- Development of custom packaging to address specific requirements
- Production of new or existing SCDs
- Replacement of plastic parts that are not usable
- Development of solutions to reduce your risk

You Are Not Likely to Get Off COTS-Free
Today’s commercially driven semiconductor market has made it difficult for Space, Aerospace, and Defense contractors to find reliable components and hybrids for their systems. Users of COTS (commercial off the shelf) semiconductor components understand that they need to do a tremendous amount of after-market work to screen potential reliability risks and/or modify their assemblies to mitigate known reliability risks. It is rare that a company can actually use these semiconductor parts as is and it is a given that the demands of our markets require many “adjustments” prior to using COTS due to the potential reliability risk. Add to this the need to be concerned about assembly differences from multiple factory locations; data sheets where typical is the most common specification limit, product changes, and short product life cycles.
Micross Hi-Rel RF Solutions was created to support companies that need product for space and Hi-Rel markets. Prior to our existence, suppliers of space level semiconductor assemblies were in need of experienced, quality suppliers. Through trust and support, some of those suppliers helped launch KCB Solutions 16 years ago, which is now Micross Hi-Rel RF Solutions. Customers searched for alternative resources in response to suppliers that had turned away from the Space, Aerospace, and Defense market due to their change in focus towards commercial products. With a foundation of 20+ years of Hi-Rel industry experience and supporting high performance in harsh environments, Micross Hi-Rel RF Solutions has developed reliable and reputable semiconductor manufacturing processes that address known reliability issues, issues that the space community has known about for many decades, which have been garnering more attention in the airborne and other military markets. We understand you must build quality in.
If you are producing an expensive long-life system, a commercial satellite, or a short-term small satellite, – you can benefit by using the Micross standard lower-cost approach. RF and Microwave surface mount semiconductors can be supplied as commercial “military off the shelf”, Military requirements Class B and H, and Space requirements Class S and Class K. Specifically, we can offer our standard product with our documented MFR flow for both Military and Space testing. In either situation, your product reputation is on the line and Micross can offer the confidence that Micross standard products provide.
Through improved yields and efficient manufacturing practices, we can offer our Standard Products at lower total cost, with shorter lead times while still meeting the requirements of traditional satellite programs. These semiconductor components are perfect for Commercial Space Applications as they offer proven space assembly processes with standard screening flows at lower cost while reducing reliability risks that the use of COTS parts contain.
Micross Hi-Rel RF Solutions can offer hermetic semiconductor parts, using proven processes that can lead to a much lower total cost solution. Whether it is early in the design process, or later after problems have already been encountered, Micross is ready, willing, and able to address your needs! Micross is working towards making these options more accessible to customers by promoting standard Hi-Rel designed semiconductors rather than another wave of COTS products that come with a very steep learning curve. Consider that Micross Hi-Rel RF Solutions has been supporting your needs for 16 years and that our market is not large enough to influence the actions of commercial companies.
