Device Overview
General Description
MPD-0226SM 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, allowing for accurate simulations using the provided S3P file taken from measured production units. 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-0226SM is available as a 4 X 4 mm QFN package. Evaluation boards are also available.
Features
- 2 GHz to 26.5 GHz In-phase Power splitting
