General Information
Control Logic
The switch is operable in four states (see Truth table, below). The switch is designed for two modes: Active and Stand-by. These
modes are controlled by the VDD signal. When VDD is high, the switch is active.
Truth Table
Electrical Test Methods
The electrical parameters for the switch were measured on test Evaluation Board provided by the switch supplier. The test Eval-
uation Board includes means for decoupling RF signals from control signal port (shunt capacitor at control signal ports).
All measurements are done with calibration plane at switch pins. The effect of test board losses and phase delay has been
removed from the results.
