EPQ-133+

RF Power Dividers/Splitters Overview

The EPQ-133+ is a wideband 90-degree hybrid MMIC power splitter/combiner from Mini-Circuits, operating within the 6 GHz to 14 GHz frequency range. It functions as a two-way device with a 50 Ohm impedance, splitting an input signal into two outputs exhibiting a quadrature phase shift. The component supports surface mount installation in a 24-VFQFN exposed pad package and maintains a typical VSWR of 1.6. It ensures minimum isolation of 16 dB and maximum imbalance of 8.8 degrees, functioning reliably across a temperature range of -45°C to 85°C.

RF Power Dividers/Splitters Feature Summary

• Provides quadrature phase shift between output ports for 90-degree hybrid operation
• Integrates MMIC technology for compact surface mount implementation
• Maintains consistent performance across a broad microwave frequency spectrum

RF Power Dividers/Splitters Applications

• Quadrature mixer circuits requiring precise phase relationships
• Single-sideband modulator architectures
• Balanced amplifier configurations demanding signal splitting

RF Power Dividers/Splitters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required packaging or tape-and-reel specifications. Confirm that the selected variant matches the intended thermal management requirements for the 24-VFQFN exposed pad configuration. Cross-reference the datasheet revision date to validate the listed electrical parameters against the most recent production standards.

RF Power Dividers/Splitters Selection Notes

Select this component when a broadband 90-degree phase shift is required between 6 GHz and 14 GHz without discrete lumped elements. The MMIC construction offers superior consistency compared to distributed designs. Ensure the application can accommodate the specific thermal dissipation needs of the exposed pad package while maintaining the required isolation levels for balanced circuit topologies.

RF Power Dividers/Splitters Part Context

This part belongs to Mini-Circuits' line of MMIC-based passive components designed for high-frequency applications. It complements other splitters and hybrids in their portfolio by offering a fixed 90-degree phase relationship over a wide bandwidth. The device serves as a critical building block for modern RF systems requiring precise signal phasing and power distribution in compact form factors.

RF Power Dividers/Splitters Replacement Considerations

Direct substitutes include the LFCW-133+ for filtering applications, though functional differences exist. Verify pinout compatibility and thermal characteristics when considering alternative 90-degree hybrids from other manufacturers. Ensure any replacement maintains the 6-14 GHz operational range and similar isolation metrics.
