MLPF-WB55-01E3 ST RF Filters

The MLPF-WB55-01E3 from STMicroelectronics is a fully integrated 2.45GHz low‑pass filter with impedance matching, purpose‑built as a companion chip for STM32WB55Cx/Rx, STM32WB50Cx, STM32WB35Cx, and STM32WB30Cx wireless MCUs. For selection, the device integrates an impedance matching network and a harmonic filter into a single miniature 1.6×1.0mm 6‑bump CSP package, completely eliminating the need for discrete matching components. Key specifications include a 100MHz bandwidth (2.4–2.5GHz), 50Ω nominal antenna impedance, 1.1dB typical insertion loss, and a deep‑rejection harmonic filter that ensures regulatory compliance. ST's IPD technology on a non‑conductive glass substrate and an ECOPACK2‑compliant, RoHS‑certified design ensure high RF performance and reliability across −40°C to +105°C. In application, it is optimized for Bluetooth 5, Zigbee, OpenThread, and IEEE 802.15.14 wireless protocols. Typical end uses include IoT sensor nodes, smart‑home devices, lighting control, building automation, industrial wireless sensors, and personal electronics where maximizing RF performance while minimizing BOM count and PCB area is critical.
