The MPBR-0022CSP3 is a small footprint MMIC DC-22 GHz 2-Way high isolation power divider/power splitter featuring high 35 dB isolation and 4.6 dB insertion loss in our compact CSP3 chip scale package. It is much smaller than a printed PCB Power Divider/Combiner. It can be used as an equal amplitude/phase power splitter or a power combiner with higher isolation compared to standard Wilkinson power dividers, making it ideal for applications that demand the highest 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 3.5 mm CSP3 package enables extreme miniaturization of SMT footprint making the MPBR-0022CSP3 ideal for applications prioritizing low SWaP. If lower loss is required, refer to our MPBR-0122CSP3.
