Overview
The MLPF-WB-04D3 is a signal conditioning component manufactured by STMicroelectronics, designed as a matched low-pass filter for the STM32WBA series microcontrollers. Operating at 2.4 GHz, this device integrates an impedance matching network and harmonics filter to optimize RF performance. It utilizes a passive integrated device (IPD) technology housed in a miniature chip-level package with bumps, facilitating high integration density.
Feature Summary
- Integrates impedance matching network and harmonics filter
- Optimized for STM32WBA series microcontrollers
- Utilizes passive integrated device (IPD) technology
Applications
- RF module integration for Bluetooth LE connectivity
- Zigbee and Thread protocol support circuits
- Matter-enabled wireless device designs
Procurement Notes
Verify the specific suffix D3 against the official datasheet to confirm compatibility with the target STM32WBA variant. Ensure PCB layout strictly follows AN6335 guidelines to maintain signal integrity. Confirm package dimensions match the ECAD model before finalizing the design.
Selection Notes
Select this component when designing for STM32WBA microcontrollers requiring optimized 2.4 GHz RF performance. The integrated IPD solution reduces BOM cost and simplifies layout compared to discrete components. Verify thermal and mechanical constraints align with the chip-level package specifications.
Part Context
This part belongs to the MLPF-WB family of integrated passive devices from STMicroelectronics. These components are engineered to replace discrete LC filters and baluns, offering higher reliability and lower profile. The family supports various STM32 wireless MCU series, providing tailored RF front-end solutions.
Replacement Considerations
MLPF-WB-05D3 serves as a related variant within the same product family. Verify functional equivalence and pinout compatibility before substitution. Consult the official datasheet for specific differences in matching networks or harmonic suppression characteristics.
