    2424=== Tx/Rx Amplifiers ===
    25  * The Tx path applies gain at three amplifiers: Tx Base Band (Tx BB), Tx RF, Tx RF PA. The Tx RF PA is always fixed at 30 dB gain. The Tx BB and Tx RF amplifiers are adjusted digitally, the range of gains is the following.[[BR]]
     25 * The Tx path applies gain at three amplifiers: Tx Base Band (Tx BB), Tx RF, and Tx RF PA. The Tx RF PA is always fixed at 30 dB gain. The Tx BB and Tx RF amplifiers are adjusted digitally, the range of gains is the following.[[BR]]
    2626   Tx BB: In [0, 3] applies 1.5 dB/step.[[BR]]
    2727   Tx RF: In [0, 63] applies 0.5 dB/step.
    … …  
    2929   Rx BB: In [0, 31] applies 2 dB/step.[[BR]]
    3030   Rx RF: In [1, 3] applies 15 dB/step.
     31 * A signal with I/Q that span full [-1,1] range of I/Q DAC input (e.g a complex exponential exp(j*2*pi*f*t) with f in passband of Tx/Rx LPFs) will be transmitted at RF with a peak power of approximately 19 dBm when Tx gains are set at maximum values (Tx BB = 3 and Tx RF =63 ), the average power will depend on the waveform.
