ADA4304-4ACPZ-RL

Product Overview

ADA4304-4ACPZ-RL from Analog Devices Inc. is a 1:4 75 Ω active RF splitter for RF signal distribution, frequency division or receiver-front-end routing applications. This product detail focuses on real RF parameters such as configuration, frequency range, insertion loss, isolation, balance, impedance and package/connector style.

The exact ordering code should be matched for connector type, package, tape-and-reel option, lead finish and environmental rating before purchase or substitution.

Applications

Multituner set-top boxes, cable splitter modules, DCR televisions and home-gateway RF distribution systems.

Active 75 Ω splitter designs that need stable output level and fewer external gain stages than discrete passive splitter solutions.

Quality & Sourcing

Antrex Electronics can support sourcing for ADA4304-4ACPZ-RL 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.
