Quartz Ladder Bandpass Filters
Joachim Köppen DF3GJ ... Kiel, July 2016
Some brief explanations
 This tool is the JavaScript version W7ZOI's method to design
ladder bandpass filters with quarz resonators with measured
properties.
 One enters the design data in the text fields, and hits the
compute button or the Enter key
 The plot shows (one half of) the frequency response of the filter.
 The table below gives the values for the shunt capacitors
 The bandwidth field turns yellow, if the terminating resistance
or any of the capacitors turns out to be negative, hence it is
impossible to construct the filter.
