Other Parts Discussed in Thread: CC1101, CC1190, CC1120

I'm on the transmit side, we have CC1101-CC1190EM 869 MHz and the reception is ANAREN A1101R08A  ...

Does no consequences for the module CC1101-CC1190EM 869 MHz can not see him put PATABLE = 0x8B (+25 dBm) 
(Application Note AN096 for CC1101-CC1190EM 915 MHz design). 
It is important to me that I made ​​a better range ... 
When it does not take into account that "CC1101 + CC1190 is not compliant with ETSI for output powers larger than +20 dbm" ....

Thanks in advance !

    I find it a bit difficult to understand what your question is.

    Do you ask if it's ok to use PATABLE = 0x8B on the CC1101+CC1190 869 MHz design?

    Are you trying to say that you see no difference in range from the +20 dBm to the +25 dBm setting?

    The question is whether it is ok to use  PATABLE = 0x8B on the CC1101+CC1190 869 MHz design?

    In the data sheet have the 869mhz limit to 20dBm ...

    Yes, but as previously stated you can't use it because the design will not be ETSI compliant. If you need higher output power than +20 dBm you should look at CC1120+CC1190 where it is possible to use up to +27 dBm.

    Whether patable same values ​​for CC1101-CC1190EM 869 MHz and CC1101-CC1190EM 915 MHz in the range of from 10 to 25dBm ?

    Can you tell me the value patable for CC1101-CC1190EM 869 MHz design, npr in range 10  to 25dBm ?

    ( I ask this because I'm trying to design for the CC1101-CC1190EM 869 mhz get you greater range ... )

    Thank you in advance ...

    Use SmartRF Studio. Select "Range extender" and the EM you are using. The 869 MHz EM has a bit more loss than the 915 MHz design due to more filtering hence the difference in the output power for a given PA TABLE setting.

    Note that you will get better link budget if you lower that datarate. Also, why is it used a Anaren module on the receive side?

    I ask one more time ....

    In the data sheet have the 869mhz limit to 20dBm ...

    The question is whether it is ok to use  PATABLE = 0x8B on the CC1101+CC1190 869 MHz design (Patable 0x8b is for  CC1101+CC1190 915 MHz design ) ?

    (I will not be destroyed amplifiers ?)

    Can you tell me the value patable for CC1101-CC1190EM 869 MHz design, npr in range 20  to 26dBm ?

    You will not destroy the amplifier.

    We don't have any PATABLE values for +20 - +27 dBm as this is not measured since it's not compliant with ETSI. But as previously said you may use the values for the CC1101+CC1190 915 design and get within a dB to the correct value.
