manufacturers Lowpass Highpass and Bandpass Filters using many design types such as:
Butterworth, Chebyshev and Elliptic Functions. The filters tabulated
on this page are Chebyshev type. Other types can be designed when
their special properties are needed.
All the filters in the Low Profile Series are a maximum of 1/2 inch
high to accommodate modern high density, low profile circuit board
design. For Lowpass Highpass and Bandpass Filters above 5 MHz our
subminiature filters are a perfect choice.
