I want to operate the bladeRF device in TDD mode in the 3.5GHz band. I will feed the transmission output of the bladeRF as an input to a Power Amplifier (PA) that has TDD capabilities and can perform RX-TX switching. Due to the nature of TDD technology, the PA requires a signal that switches the RX-TX states synchronously with the transmit and receive time slots. I believe I need to obtain this switching signal from the bladeRF.
How can we achieve this? Should I use a GPIO signal on the bladeRF? I am asking because there is currently no specific, dedicated signal output on the bladeRF for TDD switching.
Best Regards,
