U4289BM-MFP 詳細描述
Product Overview
U4289BM-MFP from Microchip Technology is a AM/FM active antenna IC used in RF, microwave or wireless front-end designs. This product detail focuses on practical RF function, operating range, control/interface requirements and sourcing relevance for engineering and procurement teams.
The exact suffix should be matched against the original BOM because RF behavior can depend on package, die or reel option, control logic, bias network and qualified operating conditions.
Key Features
- Manufacturer: Microchip Technology
- Part Number: U4289BM-MFP
- Device Type: AM/FM active antenna IC
- RF Function: Active antenna amplifier/control IC for broadcast receiver front ends
- Operating Band: AM/FM broadcast antenna front-end coverage, with U4254BM family commonly used for car-radio antenna systems
- Integrated Blocks: Low-noise amplifier, AGC/control or antenna-diagnostics functions depending on U425x/U4289 variant
- Supply / Control: Automotive/consumer radio supply and control pins defined by exact Microchip/Atmel datasheet
- Package / Case: manufacturer package/orderable suffix should be verified against the original BOM
- Design Notes: Confirm antenna impedance, AGC path, ESD network and exact suffix before replacing an active antenna IC.
Applications
Car radios, active antennas, antenna amplifiers and broadcast receiver front ends.
Automotive radio designs where antenna gain, diagnostics and external matching must remain compatible.
Quality & Sourcing
Antrex Electronics can support sourcing for U4289BM-MFP through available stock checks, BOM consolidation and alternative-lot review. For RF and microwave parts, package marking, date code, MSL handling and original-label condition 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 ICs and modules.
