USING THE RBIAS PIN TO ENABLE AND DISABLE THE HMC8414

Rev. 0 | 33 of 34

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 135. 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. The RF envelope

response (blue trace) is driven by the trigger (enable) signal (red

trace). Figure 134 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.
