UPDATED 2016-12-21: Fixed filter calculator links. They now point to a) high pass instead of low pass, and b) T configuration instead of Pi. Sorry for the confustion.
A simple RF Highpass Filter. Component values are dependent on your filter requirements. I made this as an AM broadcast band blocker, cut-off at 1.7MHz. But you can put whatever values you want on it.
This board will work as either Butterworth filter (eg: http://www.calculatoredge.com/electronics/bw%20tee%20high%20pass.htm) or Chebyshev filter (eg: http://www.calculatoredge.com/electronics/ch%20tee%20high%20pass.htm). Put in your cut-off frequency, impedance is probably 50 ohms, and 7 components. (For Chebyshev, you’ll also need to specify the pass-band ripple tolerances.) Then click Calculate, and those are your component values.
This board will take either 1206 SMT capacitors, or .1" radial capacitors. It’s laid out assuming FT37-43 toroids for the inductors, but will probably work with axial pre-made inductors too, they just won’t lay flat on the board. The SMA connectors will take either vertical or edge mounted SMA connectors.
