RF transmitter and reciever pins impedance - STM32WLE5

[viola]

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 frequencies (for example 915 Mhz).

we want to make a simulation and evaluate S12 , S11 of the whole Recieve\transmit chain between the STM32WLE5 pins to the ANTENNA  for frequencies between several 10Mhz and several Ghz .

but, the problem is that we dont have ST RF Receive/transmit pins impedance information for that frequency range (only for several frequencies as appear in AN5457 ).    is it possible to get that impedance information for the whole frequencies range ( for RF Recieve\transmit pins of the STM32WLE5) ? 

Thank You,

Viola

Hello @viola 

The application note gives some examples only. So, for other values, you have to refer to the details of the AN5457 and use them to calculate the values you are looking for.

PS: the STM32WLE5 have a Frequency range from 150 MHz to 960 MHz.

Best Regards.
