1. Test conditions: T = 25º C, Supply Voltage = +5 V, Device Voltage = 4.05 V, Rbias = 47.5 , Icc = 20 mA typical, 50 System.
2. 3OIP measured with two tones at an output power of -10 dBm/tone separated by 10 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.
