ADC-20-4-75R+

Product Overview

ADC-20-4-75R+ from Mini-Circuits is a RF directional coupler used to sample forward or reflected RF power in controlled-impedance signal paths. This product detail focuses on frequency coverage, coupling value, insertion loss, directivity or VSWR, package style and sourcing relevance.

It is suitable for RF feedback, power monitoring and antenna-line sampling designs where the exact suffix must be matched for coupling value, termination style, connector or PCB footprint, and impedance.

Applications

Directional power sampling, RF power detection, antenna VSWR monitoring, PA feedback loops, base-station RF boards and wireless front-end modules.

Useful in CATV/broadband, cellular, WLAN, UHF/VHF radio, satellite receiver, industrial RF and test equipment where a compact or connectorized directional coupler is required.

Quality & Sourcing

Antrex Electronics can support sourcing for ADC-20-4-75R+ through available stock checks, BOM consolidation and alternative-lot review. For RF directional couplers, coupling code, termination, connector or package marking, reel condition and moisture-safe handling should be checked before shipment.

For project builds, repair support or shortage coverage, 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 directional coupler parts.
