Millimeter-Wave Assemblies are fully integrated.

Press Release Summary:

Being compact at 4 in. x 4 in. x 1.5 in., Upconverter and Downconverter Millimeter-Wave Assemblies can be customized up to 120GHz frequency. Used in advanced millimeter-wave test and telemetry equipment, product integrates amplification, mixing and filtering functions along with complete connections needed for installation. BUC Upconverters offer 25-40dB Gain over 4-10GHz of bandwidth while downconverters provides 35dB gain over 4-10GHz of bandwidth with VSWR <1.8:1 for both.

Original Press Release:

Compact Millimeter-Wave Converter Assemblies Free up Valuable Board Space in High Frequency Systems

Millitech, a Microwave brand of Smiths Interconnect, has announced the release of a new series of fully integrated up and downconverter millimeter-wave assemblies (MMWAs). These active upconverters (BUC Series) and downconverters (BDC Series) can each be custom tailored to frequencies up to 120 GHz. Housed in modules as small as 4” x 4” x 1.5”, these units save significant system real estate for designers of advanced millimeter-wave test and telemetry equipment. Each compact, lightweight unit integrates amplification, mixing, and filtering functions and comes fully connectorized for easy installation.  They also offer cost savings over purchasing and integrating several independent components. Available models of BUC upconverters offer 25-40 dB of Gain over 4-10 GHz of bandwidth. Similarly, available models of BDC downconverters feature 4-10 GHz of bandwidth with Gain as high as 35 dB. Each offers VSWR <1.8:1. In addition to multiple frequency bands from 50 to 120 GHz, each series offers a designer’s choice of gain figure, output power, and noise figure. An SMA pulse/mute control input is a handy option when the capacity to power down stage 1 amplification at certain times is required. Several other custom electrical and packaging options are also available.
