Dear STMicroelectronics Support Team,
I hope this message finds you well.
We are currently using the STM32WB55RGV7 MCU as per your datasheet recommendation, we have designed RF1 Section with a Low-Pass Filter circuit, Like below attached image.
This circuit covered range was very low with Low pass Filter.
-The RF distance covered as very low distance compared with another one board with the same STM32WB55RGV7 MCU with band Pass filter Circuit. here I have included the Schematic image below.
Below attached Circuit was highest range covered circuit with Band pass filter,
-If I want to increase the RF Range in this circuit, which one is the best method, and what is different between Band pass and low pass Filter ?
