Ebyte E07-433M20S Pa Table

parts help

Hi all !

I have an E07-433M20S module but I can’t activate 20 dbm output.

I Use Arduino Nano and the LSatan SmartRC-CC1101-Driver-Lib-master library.

Could someone tell me if there is a way to activate a 20 dbm mode or how can I modify the SmartRC-CC1101-Driver-Lib-master library to obtain a PA Table that supports the power of 20 dbm ?

Thank you.

James.

While I don’t know anything about this module, a look at the CC1101 data sheet

on page 59 gives the internal register settings needed for 10dbm power output. Presumably you can figure out how to set that value in the library you you are using. I expect you would be better off posting in a wireless (preferably an Ebyte specific forum) rather than here as you will probably get a more informed answer (hopefully by someone that has done it.)

I know this manual but unfortunately I need to activate 20 dbm output and in this manual there is no useful information.

I’m having trouble finding useful information.

Thank you Peter…

Have a nice day.

From that data sheet it doesn’t look like 20dbm is an option, it looks to peak at about 12. Why do you think it can do 20dbm? You likely need to ask where ever you found that info how to do it.

The E07-433M20S module is the 20dbm version of cc1101.

Then you need to find the data sheet for the new version of the cc1101. It should have the commands to enable 20dbm. From this data sheet (found by a google search for “cc1101 20dbm”

you apparently have an additional CC1190 chip to get the 20dbm. It is possible (although the Ebyte docs don’t list it as being present) that it works automatically (that appears correct from the data sheet for the cc1190.) You likely need to determine if the Ebyte module you have includes a cc1190 in which case it should already have a 20dbm output without any modifications.

edit

Looks like this doesn’t apply. The CC1190 is only 915Mhz not 433 … It is unclear how you achieve 20dbm on the E07-433M20S although it seems to claim it is possible. An ebyte forum is likely your best bet.

I think it has a different architecture.

I found the manual, I’ll also attach the link

I wrote to Ebyte, I hope they will provide me the PA Table.

Thanks for your help.

Did you resolve this? Similar to the previous comment, I think you will find that they achieve the higher gain from an external PA (power amp) inside their module - the CC1101 settings give you up to 10dBm and the remainder comes from the PA. The PA gain is fixed - which I guess is 10dBm - add the two together and you get 20dBm. You can infer an effective PA table by adding 10dBm to the standard CC1101 settings - At least that’s my theory :wink:
