Device Overview
General Description
MPD-0226CH is a MMIC 2-way Wilkinson power divider. Passive GaAs MMIC technology allows production of smaller constructions that replace larger form factor circuit board constructions. Tight fabrication tolerances result in less unit to unit variation than traditional power divider technologies. Low unit to unit variation allows for accurate simulations using the provided measured S3P files which include the effects of the bond wires for the die and the housing for the module. Power dividers are passive reciprocal devices that can be used either as power combiners or as power dividers. Applications include Radar, Satcom, EW and test equipment. The MPD-0226CH is available as a bare die.
