1.8MHz 11th Order High Pass Filter

1.8MHz High Pass Filter designed to provide protection to receivers from strong signals in the AM broadcast band, and provides over 35dB attenuation at 1.5MHz. Low loss NPO ceramic capacitors have been used along with wire wound high Q inductors to reduce RF losses.
