Design Kit Provides Assortment of RF Transformers for CATV and Broadband Applications

Tue, 11/15/2011 - 6:45am

M/A-COM Technology Solutions, a leading supplier of high performance analog semiconductor solutions, introduced today a new transformer designers’ kit for CATV / Broadband applications. The kit features 12 transformer models covering multiple impedance ratios and wind schematics.

The MABA-000001-75KIT1 transformer designers’ kit contains full RoHS compliant components. Transformer configurations include flux-coupled, transmission line, and auto transformer. All parts in the kit are surface-mount devices featuring ceramic, plastic or FR4 substrates. In addition, baluns meeting MoCA® and DOCSIS® requirements are also included. The kit comes with a CD-ROM containing datasheets, S-parameters and application notes.

“M/A-COM Tech offers a broad portfolio of RF baluns and transformers. This designers’ kit is a representative sampling of that portfolio,” said Graham Board, Product Manager. “Covering multiple impedance ratios, schematic configurations and footprints, this kit contains the solutions you’ve been looking for.”
