From the project

KiCAD Project for a 140MHz Band Pass Filter

This repository contains the files associated with the creation of a Band-Pass Filter ideal for NOAA APT Satellite and UHF Amateur Radio reception.

The board performs extremely closely to the manufacturer's specifications.

The 140-BPF+ datasheet can be reviewed above, but the analysis has been independently validated with the following results:
