1. Test conditions unless otherwise noted: 25 潞C, Vcc = +5 V in a tuned application circuit. Vctrl is the control voltage through a 220
惟
dropping resistor as shown in the same application circuit.
2. 3OIP measured with two tones at an output power of +15 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. The gain variation range is measured as the difference in gain with Vctrl = 0V and Vctrl = 4.5V at 2.14 GHz.
