Typical Applications for HSMP-48XX Low Inductance Series (continued)
Co-Planar Waveguide
Shunt Connection for
HSMP-48XB Series
Co-Planar waveguide, with ground
on the top side of the printed
circuit board, is shown in
Figure 25. 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.
