:

1.

Maximum total power value is specified 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 differential input.

4.

10 MHz to 11.1 GHz range.

5.

Hit ratio = 5 x 10E-5.

6.

AC coupled with 100 differential output impedance.

7.

Output voltage is settable in 4 discrete steps via I2C. Default is 400 – 800 mV.
