Typical specifications reflect AM1 measured on application circuit (AM1-PCB).
Test conditions unless otherwise noted.
1. T = 25°C, Vdd = 4.5 V, Frequency = 800 MHz, 50 Ω system.
2. OIP3 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 OIP3 using a 2:1 slope rule.
3. MTBF calculated with channel temperature at 155˚C.
