System.
2. 3OIP measured with two tones at an output power of +7 dBm/tone separated by 1 MHz. The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. Data is shown as device performance only. Actual implementation for the desired frequency band will be determined by external components shown in the application circuit. The performance data does not
account for losses attributed to recommended input and output series resistances shown in the application circuit on page 3.
