F1178NBGI

Product Overview

F1178NBGI from Renesas Electronics Corporation is a dual RF-to-IF downconverting mixer used for RF and microwave frequency conversion. This product detail focuses on practical mixer parameters such as RF/LO/IF range, conversion performance, linearity, drive requirements and package compatibility.

The device is suitable for receiver, transmitter, upconversion or downconversion stages where the exact suffix must be matched for package, tape-and-reel format, connector style, temperature grade and RF layout before purchase.

Applications

Wireless infrastructure, cellular base stations, microwave radios, satellite communication equipment, CATV receivers, LNB modules, test instruments and broadband receiver or transmitter conversion paths.

Repair, prototype and shortage-support builds where original mixer suffix, package footprint, connector style and frequency plan must remain compatible with the existing RF design.

Quality & Sourcing

Antrex Electronics can support sourcing for F1178NBGI through available stock checks, BOM consolidation and alternative-lot review. For RF mixer components, date code, MSL handling, original label condition and package integrity should be reviewed before shipment.

For production recovery, 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 mixer parts.
