Application Note
Regarding Tapped Capacitor
Impedance Transformation in LC
Bandpass Filters: We
often use a pair of capacitors
to match impedances at the
termination ends of LC bandpass
filters. The circuit
consists of a shunt capacitor at
the termination followed by a
series capacitor connecting to
the high Z end of a parallel
tuned circuit. |

Ideas for Design / Wideband
filters with bandwidths in
excess of an octave can be
created by cascading a high-pass
filter and a low-pass filter. In
this design idea, nine-pole
high-pass and low-pass filters
have been constructed using a
modified equal-element design.
