Device Overview
General Description
The MPD-0222SCSP2 is a small footprint MMIC 2-22 GHz 2-Way power divider/power splitter featuring high 22 dB isolation and low 0.7 dB insertion loss in our compact 2.5 mm CSP2 chip scale package. It is much smaller than a printed PCB Wilkinson Power Divider/Combiner. It can be used as an equal amplitude/phase power splitter or a power combiner with excellent isolation. 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. The MPD-0222SCSP2 features side port outputs. For front port outputs, refer to the MPD-0222FCSP2.
