STMicroelectronics MLPF-WL-05D3
The MLPF-WL-05D3 integrates an impedance matching network and harmonics filter. The matching impedance network has been tailored to maximize the RF performances of STM32WL3xxx. The MLPF-WL-05D3 uses STMicroelectronics IPD technology on non-conductive glass substrate, which optimizes RF performances.FEATURES
● Integrated impedance matching to STM32WL3xxx● 50 Ω nominal impedance on antenna side
● Deep rejection harmonic filter
● Low insertion loss
● Small footprint
● Low profile ≤ 630 µm after reflow
● High RF performances
● RF BOM and area reduction
● ECOPACK2 compliant component
APPLICATIONS
● STM32WL3 sub-GHz wireless microcontrollersDESCRIPTION
