BGA7130
400 MHz to 2700 MHz 1 W high linearity silicon amplifier
9. Functional description
9.1 Supply current adjustment
The supply current can be adjusted by changing the value of biasing resistor R3 which
connects pin ICQ_ADJ (pin 8) to ground (see Figure 1
).
9.2 Enable control
The BGA7130 can be powered down using enable pin 6 (ENABLE). In case this control
function is not needed the enable pin can be connected to the bias supply voltage pin 5
(V
CC
). The current through the enable pin 6 should never exceed 20 mA as this might
damage the ESD protection circuitry. This can be avoided either by preventing the voltage
on this pin to exceed the supply voltage (V
SUP
) or by adding a series resistor.
