5. IDD can be estimated for frequencies
6. Idle IDD can be estimated for frequencies
frequency sensitivity number for that range. When using these numbers to estimate I
estimate should be the current at 50 MHz minus the difference in current indicated by the frequency
sensitivity number. For example: V
