DCPL-WB-00D3

Product Overview

DCPL-WB-00D3 from STMicroelectronics is a wide-band IPD RF directional coupler used to sample a controlled portion of an RF signal while maintaining the main through path. This product detail focuses on practical coupling, frequency-range, insertion-loss, directivity and interface data for engineering and procurement review.

It is suitable for designs where the exact coupling value, impedance, connector/package format and RF power rating must match the existing schematic, RF front end or test setup before purchase.

Applications

RF power monitoring, transmitter feedback, ALC loops, VSWR sensing, laboratory test fixtures and communication-system signal sampling.

Useful in production test, wireless infrastructure, telecom equipment, radar/waveguide systems and RF front-end validation where a defined coupled output is required.

Quality & Sourcing

Antrex Electronics can support sourcing for DCPL-WB-00D3 through available stock checks, BOM consolidation and alternative-lot review. For RF directional couplers, coupling value, frequency range, connector or land-pattern compatibility and packaging condition should be confirmed before shipment.

For shortage coverage, repair projects or engineering builds, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF coupler parts.
