MLPF-WL-04D3

Overview

The MLPF-WL-04D3 is a low-pass RF matched filter designed for the STM32WL3 Low-band. It operates within a passband frequency range of 413MHz to 479MHz and supports an input power level of 16dBm. The component utilizes IPD technology on a non-conductive glass substrate, housed in a 5-pin CSPG chip-scale package.

Feature Summary

• Integrates impedance matching network and harmonics filter
• Optimizes RF performance via tailored matching impedance
• Utilizes IPD technology on non-conductive glass substrate

Applications

• STM32WL3 Low-band wireless applications
• Sub-1GHz radio signal conditioning
• Bluetooth LE and Zigbee connectivity modules

Procurement Notes

Verify the specific suffix D3 against official STMicroelectronics documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target STM32WL3 Low-band design requirements before integration. Cross-reference the CSPG package dimensions with your PCB layout constraints.

Selection Notes

Select this component specifically for STM32WL3 Low-band implementations requiring integrated impedance matching. Consider its IPD construction for superior reliability compared to discrete LTCC solutions. Evaluate the 5-pin CSPG footprint against available board space and thermal management needs.

Part Context

This device belongs to the MLPF family of integrated passive devices (IPD) from STMicroelectronics. These components are engineered to simplify RF design by combining matching networks and filters into a single compact package, reducing bill of materials cost and improving system integration density.

Replacement Considerations

MLPF-WB55-02E3 serves as a companion chip for STM32WB55 series devices.
