Power Amplifiers in Beamforming Antennas

Hi Experts,

Would anyone know how Power Amplifiers ¶ for Beamforming antennas behave?

The idea would be to understand what value should be considered. Would it be just one PA for any TX/RX configurations, some % of TX/RX from active PAs, or the same amount of TX/RX from the antenna?

The main reason is due to the throughput analyzes in Atoll where the result is very pessimistic when considering PA = TX/RX, greatly increasing the system’s noise.

Thanks.
