QCN-12D+

Product Overview

QCN-12D+ from Mini-Circuits is a 2-way 90° RF hybrid splitter / combiner. This part is used for RF signal distribution, combining, quadrature splitting or front-end signal routing where frequency range, insertion loss, isolation and port matching directly affect system performance.

The ordering code should be matched for impedance, connector or package style, RoHS/reel option and mechanical footprint before replacement or BOM sourcing.

Wireless infrastructure, instrumentation, RF test fixtures and embedded RF boards that need controlled 90° phase splitting.

Quality & Sourcing

Antrex Electronics can support sourcing for QCN-12D+ through available stock checks, BOM consolidation and alternative-lot review. For RF dividers and splitters, package condition, connector condition, date code, MSL handling and original labeling should be checked before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party electrical or authenticity testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF power divider and splitter parts.
