Typical Applications for HSMP-481x Low Inductance Series (continued)
Co-Planar Waveguide Shunt Connection for HSMP-481x
Series
Co-Planar waveguide, with ground on the top side of the
printed circuit board, is shown in Figure 10. Since it elimi-
nates the need for via holes to ground, it offers lower shunt
parasitic inductance and higher maximum attenuation
when compared to microstrip circuit.
