Description
M/A-COM’s MABAES0061 is a RoHS compliant de-
vice that is equivalent to the ETC4-1-2 transformer.
This device is a 1:4 RF flux coupled step-up
transformer in a low cost, surface mount package.
Ideally suited for high volume cellular and wireless
applications. Typical applications include single to
balanced mode conversion and impedance
matching. The MABAES0061 transformer is offered
in an SM-22 surface mount package and is designed
to be utilized in both standard reflow and high tem-
perature soldering reflow profiles.
