MLPF-WL-01D3

Overview

The MLPF-WL-01D3 is a signal conditioning RF matched filter dedicated to the STM32WL3 microcontroller. It operates within a frequency range of 826 MHz to 958 MHz, supporting applications at 868 MHz. The component features a 50 ohms impedance and utilizes a CSPG-5 package with SMD/SMT termination. It is designed for surface mount mounting and functions within an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates an impedance matching network tailored to maximize RF performances
• Includes harmonics filtering capabilities
• Utilizes IPD technology on a non-conductive glass substrate

Applications

• Signal conditioning for STM32WL3 microcontrollers
• RF front-end matching in sub-GHz ISM bands
• Harmonic suppression in wireless IoT devices

Procurement Notes

Verify the specific package variant against official datasheets, as designations may vary. Confirm that the intended application aligns with the specified 826 MHz to 958 MHz operational range. Ensure compatibility with the STM32WL3 architecture before integration. Review thermal specifications to guarantee operation within the -40°C to +105°C limits under final system conditions.

Selection Notes

Select this component when designing systems centered around the STM32WL3 series requiring optimized RF performance. The integrated matching network reduces external component count. Consider the CSPG-5 package size for compact layouts. Validate that the target frequency falls strictly within the 826 MHz to 958 MHz window for optimal insertion loss characteristics.
