PI-Attenuator 15 dB - 100 W TRX
The 15 dB PI attenuator is required to safely control the output stage with 100 W radio devices.
The control power, which can be set per band by the DP-AMP controller, is then between 12 W and 30 W.
The advantage is that accidental excess power and power peaks are once again safeguarded.
