Description
The MLPF-WB-02D3 integrates an impedance matching network and harmonics
filter. The matching impedance network has been tailored to maximize the RF
performances of STM32WB5x and STM32WB1x in WLCSP and UFBGA packages.
This device uses STMicroelectronics IPD technology on non-conductive glass
substrate which optimizes RF performances.
