DB-2933-54 class of operation
DB-2933-54
● class B : a low bias point with ~100mA per transistor
● class AB : a higher bias point with ~ 900mA per transistor
To select a bias point, DB-2933-54 has a control port “BIAS”.
● The bias point is 2x 100 mA if “BIAS” is left open and in this case a DC voltage of ~5V
is present
● The bias point is 2 x 900 mA if “BIAS” is connected to ground.
"PA_ON" control port / ON-OFF bias current
● To switch-on biasing circuit, connect “PA_ON” to ground.
● To switch-off biasing circuit, left open “PA_ON”
