FPC07181

Product Overview

FPC07181 from Knowles Dielectric Labs is an RF directional coupler for sampling, monitoring or distributing RF/microwave power in controlled-impedance signal paths. This product detail focuses on frequency coverage, coupling value, insertion loss, directivity, return loss, package/connector style and sourcing relevance.

It is suitable for designs where the exact suffix must be matched for coupling value, port orientation, package style, termination option, RoHS/reel format and PCB or connector footprint before purchase.

Applications

Microwave test points, radar front ends, RF power monitoring, amplifier sampling loops and broadband measurement paths.

High-frequency boards where low parasitics, defined coupling and a compact thin-film coupler footprint are required.

Quality & Sourcing

Antrex Electronics can support sourcing for FPC07181 through available stock checks, BOM consolidation and alternative-lot review. For RF directional couplers, coupling value, frequency band, port orientation, solderability or connector condition should be verified before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, label/package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF and microwave passive components.
