CX4012LT

Product Overview

CX4012LT from Pulse Electronics is a 2-way high-isolation RF splitter/combiner transformer used for RF signal distribution, combining, test routing or antenna-feed networks. This description focuses on source-backed divider/splitter parameters such as frequency range, loss, isolation, matching, balance and package interface.

For this product family, the final orderable suffix should be checked against the manufacturer drawing for connector style, surface-mount footprint, reel format and environmental rating before purchase or substitution.

Applications

RF test systems, wireless infrastructure, antenna distribution networks, CATV/head-end equipment, phased-array feed networks and lab signal-routing fixtures.

It is also suitable for maintenance, repair and shortage support where a specific power divider/splitter part number must match an existing footprint, connector interface or qualified RF bill of materials.

Quality & Sourcing

Antrex Electronics can support sourcing for CX4012LT through available stock checks, BOM consolidation and alternative-lot review. For RF power dividers and splitters, connector condition, plating, package marking, date code and original labeling should be checked before shipment.

For project builds or legacy replacements, Antrex Electronics can coordinate visual inspection, packaging verification and third-party electrical or authenticity testing when required. This helps buyers manage risk when sourcing discontinued, allocated or hard-to-find RF passive components.
