Abstract
An ultra-high-frequency notch filter () comprises a capacitor () defining a conductive trace () on its body () and extending between its terminals (). The trace has an inductance that forms a parallel LC circuit with the capacitance of the capacitor. When mounted on a printed circuit board () to connect two segments of a signal line (), the notch filter and a ground plane () of the PCB form a virtual conductive loop having an inductance and a capacitance whose product is the center frequency of the notch of the notch filter. The center frequency is tuned by varying the width of the trace.
