MLPF-WL-02D3

Overview

The MLPF-WL-02D3 is a signal conditioning RF matched filter designed for STM32WL series wireless microcontrollers. It operates within the 826 MHz to 958 MHz frequency range as a low-pass filter. The component utilizes IPD technology on a non-conductive glass substrate and is housed in a CSPG-5 chip scale package.

Feature Summary

• Integrates impedance matching network and harmonics filter optimized for RF performance
• Utilizes IPD technology on non-conductive glass substrate for high reliability
• Features a chip scale package with bumps for compact integration

Applications

• Bluetooth LE connectivity modules
• Zigbee and Thread application designs
• Sub-1 GHz radio systems based on STM32WL3

Procurement Notes

Verify the specific suffix D3 against the official STMicroelectronics datasheet to confirm compatibility with the target STM32WL MCU variant. Ensure the design supports the CSPG-5 package footprint and thermal requirements specified in the component documentation before finalizing procurement.

Selection Notes

Select this component when designing for the 826-958 MHz band using STM32WL series MCUs. It serves as a direct replacement for discrete LC filters, offering simplified layout and improved consistency compared to LTCC alternatives. Confirm the required output power level matches the filter's specifications.

Part Context

This device belongs to the MLPF-WL family of integrated passive devices (IPDs) from STMicroelectronics. These components are engineered to simplify RF front-end design by combining matching networks and filtering functions into a single small form factor, reducing bill of materials cost and board space.

Replacement Considerations

MLPF-WB55-02E3 is a related signal conditioning chip but targets the STM32WB55 series and 2.4 GHz band, making it incompatible for direct substitution in sub-1 GHz applications.
