Description
The MLPF-WB55-01E3 integrates an impedance matching network and harmonics
filter. The matching impedance network has been tailored to maximize the RF
performance of STM32WB. This device uses STMicroelectronics IPD technology on
non-conductive glass substrate which optimizes RF performance.
