Device Overview
General Description
The MPD-0R402SCSP2 is a small footprint MMIC 0.4-2.5 GHz 2-Way power divider/power splitter featuring high 20 dB isolation and low 1 dB insertion loss in our compact 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-0R402SCSP2 features side port outputs. For front port outputs, refer to the MPD-0R402FCSP2. The 2.5 mm CSP2 package enables extreme miniaturization of SMT footprint making the MPD-0R402SCSP2 ideal for applications prioritizing low SWaP.
