WebA hairpin match is a hairpin shaped "stub inductor", generally balanced, but it could be unbalanced. It is called a hairpin because it looks like a hairpin, just like a "bobby pin" spread out a little. A shunt matching component can be used, either an inductor or capacitor, but this is typically called shunt matching because it is a shunt component
