Notes:
1. Measurements at 2.018 GHz obtained using demo board described in Figure 12.
2. OIP3 test condition: F
RF1
= 2.018 GHz and F
RF2
= 2.019 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 nal tested at production.
