Notes:
1. Measurements at 1.90 GHz obtained using demo board described in Figure 12.
2. OIP3 test condition: F_RF1 = 1.90 GHz and F_RF2 = 1.901 GHz with input power of -25 dBm per tone measured at worst side band.
3. Use proper biasing, heat sink and de-rating to ensure maximum channel temperature is not exceeded.
4. Max Input Power was characterized during the product development stage. It is not final tested at production.
