With a diode (D
2
) connected in series with the V
Bat
supply, as shown in figure 11, -70 V may be continuously applied to the
TIPX or RINGX lead.
These voltage ratings require a diode (D
2
) to be installed in series with the V
Bat
supply as shown in figure 11.
V
T
and V
R
are referenced to ground. t
ω
is the pulse width of a rectangular test pulse and t
rep
is the pulse repetition rate.
-24 V < V
Bat
< -21 V may be used in applications requiring maximum vf signal amplitudes less than 3 V
pk
(8.75 dBm, 600 ohms).
