ADL8102

USING THE RBIAS PIN TO ENABLE AND DISABLE THE ADL8102

Rev. 0 | 22 of 23

By attaching a single-pole, double throw (SPDT) switch to the

RBIAS pin, an enable and/or disable circuit can be implemented as

shown in Figure 77. The ADG719 CMOS switch is used to connect

the RBIAS resistor either to supply or ground. When the RBIAS

resistor is connected to ground, the overall current consumption

reduces to 4.73 mA with no RF signal present and 4.92 mA when

the RF input level is –10 dBm.

Figure 78 shows a plot of the turn on and/or turn off response

time of the RF output envelope when the IN pin of the ADG719 is

pulsed.
