AWR2243: Will the output power decrease when all the TX work at the same time

Part Number: AWR2243

Hi,all

I've noticed that the output power of AWR2243 is 13dBm per channel,but i'm wondering if the output power will decrease when I make all three TX work at the same time.

Hoping for your reply

BR.

    Hi,

    The output power will increase when all the Tx are enabled.

    Thank you

    There maybe some misunderstanding between us.Theoretically,When all the three TX is working together,the total tx power would be 17.8dBm. I was wondering if the power can reach this level.Or maybe there's some kind of reason which would decrease the total power.

    thanks!

    HI Chao,

                       May i ask if you have observed the total TX power decreasing with all TX's enabled? The 13dbm TX power is per channel. However, with simultaneous TX enabled the total gain(for example in beam forming) or total TX power from Antenna needs to be computed separately based on the user configuration and PCB.
