Abstract:
On-chip millimeter wave (mmW) notch filters with via stubs, methods of manufacture and design structures are disclosed. The notch filter includes a signal line comprising a metal trace line connected to a metal via stub partially extending into a semiconductor substrate. The notch filter further includes a defected ground plane connected to at least one or more additional metal via stubs partially extending into the semiconductor substrate.
