1. Test conditions: T = 25º C, Supply Voltage = +5 V, Device Voltage = +3.4 V, Rbias = 51 Ω, Icc = 30 mA typical, 50 Ω System.
2. 3OIP measured with two tones at an output power of -1 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.
