Notes
1. With a diode (D2) connected in series with the VBat supply, as shown in figure 11, -70 V may be continuously applied to the
TIPX or RINGX lead.
2. These voltage ratings require a diode (D2) to be installed in series with the VBat supply as shown in figure 11.
3. VT and VR are referenced to ground. tω is the pulse width of a rectangular test pulse and trep is the pulse repetition rate.
4. -24 V < VBat < -21 V may be used in applications requiring maximum vf signal amplitudes less than 3 Vpk (8.75 dBm, 600 ohms).
