QCN-25D+

RF Power Dividers/Splitters Overview

The QCN-25D+ is a 90-degree hybrid coupler designed for RF power splitting and combining applications. It operates within a frequency range of 1.35 GHz to 2.45 GHz, providing a bandwidth of approximately 1.1 GHz centered around 1.9 GHz. The component features a nominal insertion loss of 0.6 dB and maintains high isolation with a minimum specification of 20 dB at a 5-degree phase imbalance. Constructed using LTCC technology, it utilizes a compact 6-SMD, no-lead package measuring 3.20 mm x 1.60 mm x 1.07 mm. The device supports a 50 Ohm impedance system and functions reliably across an operating temperature range from -55°C to +100°C.

RF Power Dividers/Splitters Procurement Notes

Verify the specific suffix designation against the manufacturer's current documentation to confirm exact performance tolerances and material specifications. Ensure that the ordering information matches the required frequency range and package type. Cross-reference the datasheet revision date to validate compliance with recent design changes or alternate qualified substrate materials. Confirm RoHS status and environmental classifications prior to final procurement approval.

RF Power Dividers/Splitters Selection Notes

Select this component when a compact form factor is required for 90-degree hybrid coupling in the 1.35 to 2.45 GHz band. The 6-SMD package suits high-density surface-mount assembly processes. Consider the typical insertion loss and isolation metrics for systems requiring balanced signal paths. Evaluate thermal management requirements given the wide operating temperature range and small physical footprint.

RF Power Dividers/Splitters Part Context

This part belongs to the QCN series of miniature RF components manufactured by Mini-Circuits. The series focuses on low-cost, high-performance solutions utilizing Thin Film and LTCC technologies. These components are engineered for integration into modern wireless communication infrastructure and test equipment where size constraints and electrical precision are critical design factors.

RF Power Dividers/Splitters Replacement Considerations

The QCN-25D is the non-RoHS compliant predecessor to this model. Verify compatibility if substituting between these variants, as they share identical electrical specifications and physical dimensions but differ in environmental compliance standards.
