1. Test conditions: T = 25o C, Supply Voltage = +6 V, Device Voltage = 5.16 V, Rbias = 11.2
, Icc = 75 mA typical, 50
System.
2. 3OIP measured with two tones at an output power of +2 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.
