What made you select the Marki Microwave MPD4-0218CSP3?
I selected the Marki Microwave MPD4-0218CSP3, a 2–18 GHz MMIC 4-way Wilkinson power divider/power splitter, for this Expert Product Pick because of its outstanding combination of performance and miniaturization. One of the toughest challenges RF engineers face today is balancing high-frequency performance with reduced size, weight, and power consumption. Traditional PCB-based Wilkinson designs are bulky and introduce variation, which makes it difficult to meet the demanding requirements of radar, EW, and satellite communication systems that prioritize low SWaP without sacrificing precision or repeatability.
The MPD4-0218CSP3 solves these challenges with a compact 3.5 mm CSP3 chip scale package that is much smaller than conventional PCB-based implementations. It offers excellent RF performance, including 29 dB isolation, 0.8 dB excess insertion loss, and tight amplitude and phase balance across the 2–18 GHz band. The device can be used as either a splitter or combiner, and its consistent fabrication ensures accurate, reliable results that match simulation models. For engineers working on high-channel-count systems or advanced RF architectures, this power divider delivers the precision and footprint reduction needed for next-generation designs.
