I want to connect the AD9361 board TX output (output power < 0dBm) to an external PA. which PA can I use (2.4GHz)? couldn't find any PA module that accepts <0dBm input. thanks!
Please check below link for Power amplifiers available from ADI.
Typical PA gains will be around 20 dB and if your input signal is at -10 dBm and target power is +27 dBm you may have to use a driver amplifier.( 2 stage design,).
Check for max power output from AD9361 for your waveform (modulation) using an evaluation board for chain gain calculations.
