Hi,we want to simulate a RF chain with the STM32WLE5 Device using AWR . High Power mode , 22 dBm transmit power. Lora In AN5457 there is Input \ output impedance information of RF Reciever \ transmit pins of the stm32wle5 but only for certain fr...

Hi ,Regarding working with the STM32WLE5 with SUBGHZ block in the CUBE-MX.in the clock section tab in the CUBE-MX I dont see any mention of the RF-PLL clock. if i understood correctly - in order to work with the LORA SUB-GHZ BLOCK i need to supply a ...

Hi, I just want to make sure that it is possible Using STM32WLE5 SUBGHZ IN HIGH-POWER MODE (22 DBM) , higher frequency band , WITH THE INTERNAL LDO ? (without the internal SMPS ) I am asking because i see in the CUBE-MX under the tools tab that th...

Hi , is it possible to get the RX sensitivity of the STM32WLE5JCI6 in other LORA conditions then mentioned in the Datasheet ? our LORA parameters are:PER=1%BW= 20.8Khz to 125KhzSF= 7 to 11split RF paths for RX and TX using RF SWITCH Thank you,Viola

Hi ,In table 32 in the Datasheet we can see TXDRP parameter which describes RF output power drop versus supply voltage. is there also RF frequency offset as a result of the supply voltage drop ? If the answer is yes - can you estimate it ? Thank you,...

Hi STTwo-32, Regarding the Internal ticket - I just want to add that you can see the problem even if you open example code for the nucleo board in the cubemx for STM32WL that uses the subghz block and you will see the problem. Thank you, Viola

Thank you, waiting for your reply.Also, in the clock section tab in the CUBE-MX I dont see any mention of the RF-PLL clock. if i understood correctly - in order to work with the LORA SUB-GHZ BLOCK i need to supply a 32 Mhz HSE clock . I dont see in t...

Hi , As you can see in the picture below , I dont have the option for "high power" when "SMPS" is OFF

It is mentioned in the datasheet that there is Auto-calibration of the RF-PLL after transition between certain RF power saving modes or when invoked manually . But i didnt see any additional info regarding that .perhaps that also insures there is n...

Hi,My RF Frequency source is 32MHZ TCXO which has +- 0.1 PPM Frequency offset for +-5 percent change of TCXO supply voltage.But , my question is regarding the Synthesizer inside the STM32WLE5 - Does changing the one of the power supplies for the STM3...
