IWR1443: Transmitter Output power VS temperature

Part Number: IWR1443

Hello, do you have the characteristic curve of IWR1443 transmitter power vs temperature?
Does the lower the temperature, the higher the transmitter power?   Thank you !

    Hello Liu, 

    I might not have a curve to demonstrate the relation between Transmitter Power and temperature but I can tell you about some basic dependency. 

    Yes, over temperature, TX power starts to drop, which means higher the temperatures, lower the power. Also, across the 76-81GHz frequency band, you will also see a larger roll-off at higher temperatures. 

    Hope this helps and clarifies your concerns. 

    Regards,
