Notes:

1. Tested on Evaluation Board TB-340, See Figure 3.

2. Insertion loss values are de-embedded from test board Loss (test board’s Insertion Loss: 0.10dB @100MHz, 0.35dB @1000MHz, 0.60dB @2400MHz, 0.75dB @4000MHz).

3. Input IP3 and 1dB compression degrades below 1 MHz. Input power not to exceed max operating specification for continuous operation.

6. Permanent damage may occur if any of these limits are exceeded.

7. Operation between max operating and absolute max input power will result in reduced reliability.
