Notes:
1. Maximum total power value is specied across the full temperature and voltage range.
2. From power-on and end of any fault conditions.
3. After internal AC coupling. Self-biasing 100 Ω differential input.
4. 10 MHz to 11.1 GHz range.
5. Hit ratio = 5 x 10E-5. Valid for all settings in Figure 1.
6. Hit ratio = 5 x 10E-5. Valid only for the shaded setting in Figure 1.
7. AC coupled with 100 Ω differential output impedence.
8. Settable in four diecrete steps via the I
