STMicroelectronics MLPF-WL-0xD3 Low Pass Filters

STMicroelectronics MLPF-WL-0xD3 Low Pass Filters are optimized for use with the STM32WL3x Multiprotocol LPWAN 32-bit microcontrollers (MCUs), providing a highly integrated and efficient RF solution for wireless Internet of Things (IoT) applications. These filters complement the STM32WL3x's integrated sub-GHz radio, ensuring optimal signal integrity and reducing unwanted harmonic emissions in RF communication. With a compact footprint and low insertion loss, the STMicroelectronics MLPF-WL-0xD3 filters are well-suited for space-constrained designs, such as LoRaWAN™, Sigfox™, or other low-power wide-area network (LPWAN) applications. Together, the MLPF-WL-0xD3 filters and STM32WL3x MCUs deliver robust and reliable performance in IoT devices, wearables, industrial automation systems, and smart city solutions.

The MLPF-WL-0xD3 filters use STMicroelectronics' IPD technology on a non-conductive glass substrate, which optimizes RF performances.
