Typical Applications for HSMP-482x Low Inductance
Series
Microstrip Series Connection for HSMP-482x Series
In order to take full advantage of the low inductance
of the HSMP-482x series when using them in series
applications, both lead 1 and lead 2 should be connected
together, as shown in Figure 14.

Microstrip Shunt Connections for HSMP-482x Series
In Figure 15, the center conductor of the microstrip line
is interrupted and leads 1 and 2 of the HSMP-482x diode
are placed across the resulting gap. This forces the 0.5
nH lead inductance of leads 1 and 2 to appear as part of
a low pass filter, reducing the shunt parasitic inductance
and increasing the maximum available attenuation.
The 0.3 nH of shunt inductance external to the diode
is created by the via holes, and is a good estimate for
0.032" thick material.

Co-Planar Waveguide Shunt Connection for HSMP-482x Series
Co-Planar waveguide, with ground on the top side of
the printed circuit board, is shown in Figure 17. Since
it eliminates the need for via holes to ground, it offers
lower shunt parasitic inductance and higher maximum
attenuation when compared to a microstrip circuit. See
AN1050 for details.
