Description and Applications
This device is a silicon glass PIN diode chip fabricated with
M/A-COM’s
patented
HMIC
process.
This
8.0m
I-region length device features six silicon pedestals
embedded in a low loss, low dispersion glass. The
diodes are formed on the top of a pedestal and
connections
to
the
backside
of
the
device
are
facilitated
by
making
the
pedestal
sidewalls
electrically conductive. Selective backside metallization is
applied
producing
a
surface
mount
device.
The
topside is fully encapsulated with silicon nitride and has
an
additional
polymer
layer
for
scratch
protection.
These
protective
coatings
prevent
damage to the junction and the anode air-bridge
during handling and assembly. The vertical silicon
diode topology provides for a highly efficient heat trans-
fer medium. These surface mount devices are suitable
for usage in higher (3W avg.) incident power switches.
Small parasitic inductance and excellent RC constant
make
these
devices
ideal
for
absorptive
SPST,
reflective SP2T switches, and attenuator circuits, where
higher P1db and power handling values are required.
