Typical Applications for HSMP-481x Low Inductance Series
Microstrip Shunt
Connections for
HSMP-481x Series
In Figure 8, the center
conductor of the microstrip
line is interrupted and
leads 1 and 2 of the
HSMP-481x series diode are
placed across the resulting gap.
This forces the 1.5 nH lead
inductance of leads 1 and 2 to
appear as part of a low pass
filter, reducing the shunt
parasitic inductance and
Microstrip Series
Connection for
HSMP-481x Series
In order to take full advantage of
the low inductance of the
HSMP-481x series when using
them in series applications,
both lead 1 and lead 2 should be
connected together, as shown in
Figure 7.
increasing the maximum
available attenuation. The
0.3 nHof shunt inductance
external to the diode is created
by the via holes, and is a good
estimate for 0.032" thick material.
