EP4RKU+

RF Power Dividers/Splitters Overview

The Mini-Circuits EP4RKU+ is a monolithic microwave integrated circuit (MMIC) 4-way 0° power splitter/combiner designed for wideband operation from DC to 18 GHz. It provides equal power division among four output ports with high isolation and low insertion loss. Key electrical specifications include a minimum isolation of 11 dB, a maximum voltage standing wave ratio (VSWR) of 1.8, and a maximum imbalance of 19°. The component features an insertion loss of 4.2 dB and operates within a standard 50-ohm system. It is housed in a compact 32-VFQFN package with an exposed pad, measuring 5.00 mm x 5.00 mm x 1.00 mm, suitable for surface-mount applications requiring reliable RF signal distribution.

RF Power Dividers/Splitters Feature Summary

• Provides precise 4-way power splitting or combining with 0-degree phase alignment across the operational bandwidth
• Delivers consistent performance with specified isolation and VSWR limits for signal integrity
• Utilizes MMIC technology for compact integration into high-frequency circuits

RF Power Dividers/Splitters Applications

• Wideband RF signal distribution networks
• Phased array antenna systems
• Test and measurement equipment signal routing
• Communication infrastructure components

RF Power Dividers/Splitters Procurement Notes

Verify the specific datasheet version corresponding to the 0 Hz to 18 GHz specification range, as manufacturer documentation may reference alternative frequency bands such as up to 31 GHz for similar family members. Confirm that the 32-VFQFN package orientation and thermal pad requirements align with your PCB layout guidelines. Ensure compliance with RoHS3 standards if environmental regulations apply to your assembly process. Cross-reference the part number suffix to confirm it matches the exact electrical parameters required for your design.

RF Power Dividers/Splitters Selection Notes

Select this component when a 4-way split is required with minimal phase deviation across a broad spectrum extending to 18 GHz. Consider the 4.2 dB insertion loss impact on system gain budget. Evaluate the 32-VFQFN footprint against available board space. Compare isolation levels against adjacent channel requirements. Ensure the operating temperature range meets your environmental constraints before finalizing the selection for production.

RF Power Dividers/Splitters Part Context

The EP4RKU+ belongs to Mini-Circuits' EP series of MMIC splitters and combiners. This family includes variants like the EP2RKU+, which offers a 2-way configuration. These components are engineered for high-reliability RF applications where size and performance are critical. The series utilizes advanced semiconductor processes to achieve wideband operation while maintaining small form factors, making them suitable for modern wireless communication systems and instrumentation.

RF Power Dividers/Splitters Replacement Considerations

The EP2RKU+ serves as a functional substitute if only two output ports are required, offering identical technology but different port count. Verify that any replacement maintains the same 32-VFQFN package dimensions for direct board compatibility. Check that the replacement part supports the necessary frequency range and power handling capabilities for your specific application.
