Notes:

1. Measurements are standardized against short-circuit at socket terminals.

2. Off-isolation is measured between COMx and the off NCx/NOx terminal on each switch. Off-isolation = 20log (VOUT/

VIN).

3. On-loss is measured between COMx and the on NCx/NOx terminal on each switch. On-loss = 20log (VOUT/VIN).

4. Signal direction through the switch is reversed; worst values are recorded.
