IWR1443: Can two TX pins be connected to get more tx power?

Hi,

I used single antenna, can I connect two TX pins  to get more tx power?

Which two TX pins can be connected?

    Hello,

    Yes, not on the EVM you could have a power combiner from 2 Tx outputs, the combined output would go to the antenna.

    The Tx power to consider is the radiated Tx power.   Having multiple Tx  patch antennas, you can enable Tx1, Tx3 on the EVM, with the same chirp to get a higher radiated power (EVM).   You currently can't enable 3 Tx for the same chirp. 

    If you were designing a board with higher than 12dbm for a waveguide output (instead of patch antennas), you can use a power combiner, that is an RF method to combine 2 Tx, these must have matched phase and layout distance, from the device ball to the power combiner attach point.
