Description The CA3039 consists of six ultra-fast,
low capacitance diodes on a common monolithic substrate.
Integrated circuit construction assures excellent
static and dynamic matching of the diodes,
making the array extremely useful for a wide variety of applications
in communication and switching systems.
Five of the diodes are independently accessible,
the sixth shares a common terminal with the substrate.
For applications such as balanced modulators or ring
modulators where capacitive balance is important,
the substrate should be returned to a DC potential
which is significantly more negative (with respect to the active diodes)
than the peak signal applied.
