There are 4 filters per board plus a test jig. For $2 you can get 20 filter boards and 5 test jigs made. Cheap as chips yeah.
The filter is G3UUR Cohn Min Loss, the caps are all the same value and set the width of the passband.
The outer area of the solder mask are pulled back to allow for a shielding cap to be soldered over the top.
