Typical Third Order Intermodulation Test Setup

Power ON and OFF sequence

It is very important that the user adheres to the correct power-on/off sequence in order to avoid damaging the

device (Note 3).

Power ON

1) Apply voltage supply - VDD

2) Wait 100μs or greater and then apply logic supply - VIO

3) Wait 10μs or greater and then apply RFFE

4) Wait 5μs or greater after RFFE Trigger falling edge and then apply the RF Signal

Power OFF

1) Remove the RF Signal

2) Remove RFFE

3) Remove logic supply

– VIO

4) Remove voltage supply

– VDD
